Yellowing & Brown Spot's on leaves??? Help!

[irieeyes808]

I don't know what to make of this as I am not very good at diagnosing deficiencies or toxicities in the reference books. They are growing slowly have been topped most are deep chunk crosses. Temps are in the high 80's, I don't know but really worried I don't have a ph pen and just giving tap water with some flora nova and at times a little fish emulsion, They are in mostly peat some Lowes type potting mix, perlite and vermiculite? Any ideas or help?

 

[HeadyPete]

you need a ph pen. Tap water is usually high ph.

Yeah, worst part about paying for PH and EC testers is once you get the hang of things you can put them in mothballs.

If your Ph is around 7 you could try using Promix next time. Just a suggestion, I know it doesn't help you now though. Are you letting the soil get dry slightly before watering again? Also, you could lower nutes if your going a little high and see what happens. \\

What I usually do when all else fails is use a brand that has micro nutes or try some Cal mag, just a sugestion. Sorry I can;t help more.

Man they look sad today I noticed some dying leaves more rust spots and slow growth starting with older leaves moving up the plants??? I am on a budget so help please...

808, Do you have any D-lime in your mix?
Kinda looks like a calcium def.
And some other nutes being locked out (pos.PH )

Check this link, scroll down to calcium def. and see if it sounds like what's happening.

I have been feeding flora nova and some fish emulsion I think they are a little over waterd. I really think my ph is off and have always had issues with the flora nova stuff., so I need some garden lime and ph tested waterr???

 

[Asil]

I am willing to bet that you are running to high of a ph. My tap water here is a ph of 8 and the RO water I get at the store from Culligan is a ph of 7. I would at least try to get some drops and check your ph. Once you get it adjusted you will see a change in the growth.

 

[HeadyPete]

you need ph down and at least pool and spa test strips.

 

[Asil]

I would use RO or distilled water if you tap water is bad. Have you had you tap water tested?

 

[irieeyes808]

no man haven't tested just don't really have the funds right now to buy much stuff, and just got home from seeing the movie UP, which was soo awesome in 3D and just sad about my girls they are getting worse. Slowly progressing up the trees to younger vegitation. I bought from CVS some epsom to foliar and will wait til I hear drom you guys if I should water with epsom?????? Man I am just so bummed.

PH strips are cheap an works just as good they can be found on ebay for $7 shipping included

 

[montehierba]

quick flush with low ph and leave them alone with low relative humedity. and good ventilation.a bit high ph looks like and some salt built up, not much.not that bad

 

[irieeyes808]

could I just repot in oceans forest and then water with store bought water or distilled?

You should stop being so stubborn and do what we told you to do. If you have choices to makes, then choose wisely. Either you are gonna grow your own...or you are gonna go see movies. You are either gonna go see UP!, or you are going to smoke yer own and get UP!!! If you don't have the resources to do both, then you can't come here looking for free magic answers to your problems. Growing is a commitment and a way of life. Plants need proper attention very regularly and that takes commitment and time and patience and some money. They require certain environmental basics to live and thrive and if you don't provide those, the plants will not grow. We are replicating what nature so perfectly already does. It's costly, it's labour-intensive and it's complex and complicated and you can't expect to "just toss a seed in a cup on a windowsill and poof!.....jars of smoke-able bud". It's not an Easy Bake Oven....

If you don't correct the ph, they are toast.

I don't know how much plainer I can put it.....test strips are a few bucks at any home reno center or pool supply...but you will probably need some PH down (and PH UP for when you add too much down and need to raise it back up) from a hydro store.

You need to have certain equipment and knowledge to grow pot indoors - there is no way around it.

Transplanting to FF may help but what happens when the ph drifts off from your incorrect ph waterings and the problems start again? You need to be able to identify the problem and correct it properly.

 

[HeadyPete]

Please fill this form out completely, you probably have multiple issues happening.

The hotter the temps, the less food you feed. Your temps are too high for pot. When you overfeed, ph goes up, plants yellow (because the water is literally pulled from the plants through the roots back into the soil from the higher salt concentration. This is simple osmosis), nutes get locked out. Add to that out of whack PH, which makes certain nutrients unavailable to plants, and you have a death sentence, unless corrected by flushing like hell with proper ph adjust (to 6.3) water. Tap is fine as long as it isn't too hard. 200 ppm is about the upper limit. Tap provides some cal and mag, but you may need to supplement. Some strains like more than others.

Oh yeah, if you use that epsom on your girls at this point, they are dead.

SOIL:

How long has this problem been going on?
What STRAIN are you growing?
What was the establishing technique? (seed or clone?)
What is the age of your plants?

What substrate/medium are you using? What brand of soil mixture are you using?(percentage of perlite, vermiculite...etc?)
What Nutrient's are you using?
How much of each nutrient are you using with how much water? *Knowing the brand is very helpful*
How often are you feeding?
If flowering, when did you switch over to using Bloom nutrients?
What order are you mixing your nutrients? (example: veg nutes 1st, bloom 2nd ect)
What is the TDS/EC/PPM of your nutrients used?
What is the pH of the "RUN-OFF"?
What method of pH test was administered? Using Strips? pH pen?
How often are you watering?

What is the current Air Flow? (cfm etc.)
Tell us about your ventilation, intake exhaust and when its running and not running ?
Is the fan blowing directly at plants?
Is the grow substrate constantly wet or moist?
Is your water HARD or SOFT?
What water are you using? Reverse Osmosis (RO)? Tap? Bottled? Well water? Distilled? Mineral Water?
Are you using water from a water softener?
Has plant been recently pruned, cloned or pinched?
Have any pest chemicals been used? If so what and when?
Are plant's infected with pest's?

HP takes growing VERY seriously.

ie: your plants are screaming bad pH, so go ahead and spend the $10 or so that pool drops are going to cost and stop trying to throw nutes at your problem.

Hi Irie....you can't receive PMs yet (probably post count), but I got yours. Here is the reply I tried to post.

Hi I wish you the best of luck. This frustration is part of the growing pains of growing but once you start to get the hang of some of this, it will seem much easier. Don't give up, even a bad experience is still experience.

As for the foliar....I have never had to foliar my plants, ever. Some peeps do, but beware you are raising humidity and encouraging mold by spraying. Also, I don't want any spray residue of anything on the bud I am gonna smoke.

If your ph has locked out everything, adding more of something will make it worse. It will still burn your plants, but they can't access the nutrient. The nutrients literally bind to each other and stick to surfaces, if the ph is out.

Again you need to flush flush flush with properly adjusted water of 6.3 ish ph.

I will help you through, but you still have to learn and you will.

Take care.

Hey HP, your right man I went today and bought some Roots Organics soil repotted, and tomorrow I get PAID! So I will get a ph test kit and the up down solution and if I have enough I will get a pen to test ppm, Thanks all and yes it seems as every grow I am learning something new. I was only spraying because humidity was very low like 35%.... I wish I had an unlimited budget so I could spend all the money I needed on all of the necessities but I live the best I can right now, thanks again.

Hey dude

Same stuff happened to me with my last grow. I'm guessing this yellowing and browning is only happening on the lower leaves right? With me it was a sign of my plants being really rootbound. I had them in containers that were too small and the plants started to feed off the lower leaves fto supply energy for new growth. As soon as I transplanted the problem stopped spreading and damaged leaves started looking better. I also think watering more frequently with added nutes would probably do the trick; however, i've never tried this. My suggestion would be to transplant into a soil with some nutes in it like ocean forest. Good luck
