hey stitch,
is this normal the first set of trueleafs are burning?

now the second set is turning light and the tip is burning.

Yes, when those firt sets of leaves go it's time to start feeding a weak mixture of nutes for it's first feeding.

Also the plant looks a little underwatered/overwatered... sometimes they are hard to tell..... are those jiffy pots?
Ya, it's about time to feed them now, check the main sets of leaves, the tips are getting lighter green and starting to turn yellow.... what soil are they in and have you fed them yet?

 

[MynameStitch]

Janiis, dude that is hard to tell if they are brown or red.... the only area that I think may be affected if it's rot is the plant on the right side, if you notice it's brown on that big mass set of roots..... spray some fresh water on the roots or does it sorta smell in the res? That is a lot of nutes you got added there..... I would not raise it if I were you; it's very obvious that the strain can take a lot of nutes....how often do you test your ppm's?

When you test your ppms does your pH rise or fall.....

 

[MynameStitch]

Canna smoke how often are you feeding them, those spotting affects are 2 things either calcium or pH problem and since you don't know your pH you need to water it and let some run off come out so you c an test it.

Can you get some more pictures of them without the hps light on and some more pictures of them, but not from directly from the top, get like a side/top picture of them?

also how long ago did this happen and what problems are you seeing the spotting? Anything else?

 

[MynameStitch]

Gab Jaz, I see a few things wrong here.... first you never want to put a plant into a big pot, this contributes to over watering and slow stunted seedlings.....

Another thing, with them being in 2 different soils they are going to have 2 different pH.

As for the soil fox farm is in... how long were they in this mixture before you started to feed them? 7 to 10 days? If so I grantee they are getting burned... you got your hands full if it is burnemd; because you have to water with a lot of water to properly flush out soil and since there is way too much soil and not enough roots your plants going to be over watered for quite some time You should always wait at least 25 days before feeding them, the one in the FF mixture....

Do you have any pictures of the problem?

Honestly I would invest in a PH pen..... what value does your strips go up to and how low do they go down too?

What pH value.....

Another thing, you never want to cut off leaves unless they are about to fall or fall on there own; then you can remove them; if you remove affected leaves that are not ready to be dropped the plant will go to other leaves more quickly than what it would if you let it use it's stored nutes in affected leaves.

Without pictures it's impossible to tell; so please get some pictures of the plants that have the problem.

Pro mix should not have a pH value of 7.... high pH levels will lock out nutrients and even though they are there, they won't be able to absorb them.

hey stitch,yep there jiffy pots and the seed was started in a jiffy pellet. ive not figured the water thing out on them.its always on or the other,to wet/to dry and the soil around the jiffy pellet is seed starter by the same jiffy bunch.i dont like peat. ill make it some tea and see if it helps the growth has slowed down.i was thinking this was from lack of oxygen as it was water logged.i couldnt get it to dry out.

i have another plant that was started at the same time there differnt strains.so its not a good comparison although its a mostly indica plant.its over 16" taller.i started it in a jiffy pellet and put it in a beer cup and m.g. soil.ill take pics of them both side by side,and show you the differnce.

 

[jyme]

ok these two plants started at the same time one in a beer cup one in a jiffy cup

and this one looks like it got to close to the light

Hi Stitch, I'm testing ph and EC almost everyday. pH is stable, EC is rising a little bit, 1,55 right now.

Well, thanks for your info. I'll try to add some rot drug inside the res and we'll see...

Grrr, why can't I just get it right?!

Grrr, why can't I just get it right?!

Hey all... hello Stitch... so, here's some pix of one of my girls. As you can see, it's overall pretty healthy. I adjusted the pH recently (2 or 3 days ago), adding 1TB of Hydrated Lime per gallon and watered each plant thoroughly. However, before I start my feeding schedule again, I figured I should probably check and see if this problem is nute burn, or what. In other words, should I give H2O or nutes?... so without further ado:

SOIL:

How long has this problem been going on? About 4 weeks
What STRAIN are you growing? White Widow from Nirvana
What was the establishing technique? (seed or clone?) Clone
What is the age of your plants? Around 9 weeks, from the start of cloning
How long have they been in the soil mixture they are in now? About 4 weeks
How Tall are the plants? Various... average of 2'
What PHASE (seedling, vegetative or flower) are the plants in? Flowering
What Technique are you using? (SOG, SCROG etc) Perpetual harvest
What size pots are you using? (Include how many subjects to pot) 10" pots/2 gallon?
What substrate/medium are you using? What brand of soil mixture are you using?(percentage of perlite, vermiculite...etc?) Pro Mix ammended with 1TB fine dolomitic lime per gallon
What Nutrient's are you using? Fox Farm- solubles and liquids, Cal/Mag, ProTekt, pH balanced to 6.5... should I go higher since I'm using Pro-Mix?
How much of each nutrient are you using with how much water? *Knowing the brand is very helpful* 1/4 strength of soil schedule
How often are you feeding? 1x per week, thus far
If flowering, when did you switch over to using Bloom nutrients? Almost immediately (1/2 and 1/2 first watering)
What order are you mixing your nutrients? (example: veg nutes 1st, bloom 2nd ect) Solubles, then liquids
What is the TDS/EC/PPM of your nutrients used? Unknown
What is the pH of the "RUN-OFF"? Dunno since I adjusted, but my "Control Wizard" (see pic) says ~6.6.
What method of pH test was administered? Using Strips? pH pen? Control Wizard soil pH tester- usually I use GH drop-based kit with vial in conjunction with the Control Wizard
How often are you watering? 2x per week-ish
When was your last feeding and how often are you feeding? 6 Days ago
What size bulb are you using? 600 HPS
What is the distance to the canopy? About 6 inches, air-cooled hoods
What is your RH Factor? (Relative Humidity) 55-60%
What is the canopy temperature? Unknown- cool enough
What is the Day/Night Temp? (Include fluctuation range) Day: 85, night: 70-75
What is the current Air Flow? (cfm etc.) 140 Cfm's just for cooling lights/B]
Tell us about your ventilation, intake exhaust and when its running and not running ? 2 16" oscillating fans running 24/7, lights cooled during day
Is the fan blowing directly at plants? Yes, on low
Is the grow substrate constantly wet or moist? No
Is your water HARD or SOFT? Soft
What water are you using? Reverse Osmosis (RO)? Tap? Bottled? Well water? Distilled? Mineral Water? Well
Are you using water from a water softener? No
Has plant been recently pruned, cloned or pinched? No
Have any pest chemicals been used? If so what and when? No
Are plant's infected with pest's? Yes- thrips and fungus gnats, minor in each case

p.s.- Do I need an EC/ppm pen? Would that make my life easier, even though I'm in soil?

 

[FinestKind]

For that matter.... what the hell is going on here?

 

[jusageeza]

great post im learning alot on ere

 

[MynameStitch]

Jyme, the one in the jiffy pot, I would try to avoid using those, because they keep too much moisture for small seedlings...... jiffy pellets are perfect to use.

As for the other plant ya, light did get too close; the one bigger plant that has the spotty effect, that is old and it looks like it's not spreading?

 

[MynameStitch]

Hi Stitch, I'm testing ph and EC almost everyday. pH is stable, EC is rising a little bit, 1,55 right now.

Janiiis

If your EC is rising then you either have bacteria in the water from the root rot, or your nutrient levels are too high and the plants are removing more water than nutes...... I would first get some root rot remedy in there....

Do you live in Europe?

 

[MynameStitch]

Finest, that is a lot of hydrated lime...... hydrated lime works quickly and since that is in there and you use cal mag.... that is too much plants are having problems with high micronutrients.

The pH seems like it's swinging too.......

Fox Farm- solubles and liquids, Cal/Mag, ProTekt, pH balanced to 6.5

Why are you pH balancing it?

Wht kind of fox farm.... what type of nutrient and how much of each..... 1/4 of there feeding schedule....

Dude. those meter pH sticks are junk, they always say the pH is in that range./
Get a pH pen and some calbration fluid or get some pH test strips.

Your pH is out of wack, high levels of micronutrients in the soil is locking out other nutrients, not to mention when you do feed they can't absorb it.... the decay of the leaves tells me something is going on where it's damaging root hairs..... so I would flush it and start a new first... get a pH tester before flushing so you can tell before and after results.....

Another thing, depending on what is 1/4 feeding schedule you could end up not using enough and it contributes to the problem... but I honestly think the pH is causing a problem herel you need to get that under control first before anything else...

those leaves look like they are losing nitrogen/ potassium...

Is there any spotty effect in the leaf veins?

Also depending on what promix you got they already have lime added in the mixture.....

With you pH adjusting t your throwing the pH really off..... this must be fixed first, you will need to flush your plants out; it's a must you getting pH meter and some calibration fluid...... cause the pH is all out of wack


too much calcium/magnesium is like watering your plants with hard water, they end up getting spotty effects like showing/mimic calcium deficiency......

It ends up being hard water damage too.

I know, I know, I get it now- I'm getting a pH meter

I've been pH-ing the solution because... I dunno, it seemed like the right thing to do. If I don't pH it, the solution has a fairly low pH, which I figured would lower the overall pH of my soil and use up the lime, no? I just thought that it was common practice.

As far as the Cal/Mag itself, I have been using 1/2 the recommended dosage on that one, as well.

What is "proper" pH for Pro-Mix? (It is Pro-Mix BX, btw) I found a thread of yours that said the pH should be I think around 5.5? I've been trying to keep it around 6.5 (using the GH pH test kit and testing the runoff... my grow guy said the kit is pretty accurate)- perhaps this is why I'm locking out nutes?

Thanks again for your help, it is much appreciated!

Promix BX is already pH balanced and no lime needed if I remember correctly; With you adjusting the pH, your pH is going up and down and it's not stable this is why you are seeing what you are; nutrients have pH levels they need to be at for the plant to be able to absorb them the most, if it's going up and down it can't get certain nutrients even if it's plentiful.

This is where a lot of people mess up, because it looks like they are hungry,but they are not and they end up burning them.
What you need to do is defiantly get a pH tester and then flush your plants really good with a lot of water... what size pots are you using?

I assume this grow guy is a hydro shop guy? I would never listen to them unless they know how to grow pot. I made a thread called the hydroguy fuck up thread and you will see how bad hydro guys are at giving grow pot advice lol.

I say pH is in a range, because some strains are more tolerable to pH swings so the pH range is 5.5 to 6.3

Most of the sweet spots is around 6.0 or a little above it.
With the amount of lime in there and your water having it and your cal mag your going overboard with it and there is overabundance of it, this will also contribute to nutrient absorption problems... hard water

Hey happy guy. the las picture to the right you uploaded, the cotyldons natrually yellow and die off, this is once the plant can establish it's root system it does not need it anymore and they die.

For the rest of it,. your plants are hungry, when you use distilled water you remove many micronutrients from there diet, unless you have a nutrient to supplement them with.

Since your only using fox farm there is not enough micros in there if any. You must either stop using distilled and use tap water that sat out or get a hold of some cal mag, sensi cal earthjuice products too.... micronutrients, but earthjuice microblast does not have calcium.

You can get some dolomite lime and sprinkle it on the top soil and when you water it will release calcium/mag over time.

Your plants are hungry for calcium really bad and magneisum, that is why your plants veins are green and yellow this is magneisum problem.

SO get them some micros and your problem fix, depending on what way you use to fix it if you continue to use distilled water you will need to suppliment micros every water.

 

[Cannasmoke]

Canna smoke how often are you feeding them, those spotting affects are 2 things either calcium or pH problem and since you don't know your pH you need to water it and let some run off come out so you c an test it.

Can you get some more pictures of them without the hps light on and some more pictures of them, but not from directly from the top, get like a side/top picture of them?

also how long ago did this happen and what problems are you seeing the spotting? Anything else?

I'm watering whenever I think they need watering, I lift the pot to decide, at that point it was roughly once every 2 days, I cant get any pictures at the minute as it was a mates phone I used, I was feeding them Calcium mono nutes along with Mag, I think I maybe went too far with them.

the grey spots are now brown and their leaves are yellow, all new growth above them dont have the spots now but the whole plant is a very light color, bordering on yellow but still green.

I'm thinking of flushing.

the color of my Easy Ryder is very similiar to dmans above, also in canna coco.
