Canna, I Hate to ask, but can you get some pictures of them without the HPS light on.... orange light is too hard to see the coloration of the plant and where it's being affected at......
interesting, i figured since RO worked well for plants, it would be the same for distilled, but i had never thought about it lacking many micronutrients that are in tap water...perhaps i'll switch to tap water once i finish off all of my distilled.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.
Happy, then your plants will do fine then, it will slowly go away, dolomite lime is released slower over time, so with the size of your plant you will be alright. Damaged leaves won't recover so make sure it's not spreading to areas that did not have it before.
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
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.
there is something happening to the new growth, but it's just that the tips of the leaves are yellowing, but only the tips. iirc this is something i can fix by giving my nutes, i just haven't been able to feed because of my laundry list of previous problems (3x concentrated nute solution lol, stupid stoner mistakes) since i had been flushing and didn't feed right when i transplanted. regardless, my plants are looking much better now, thank you for giving me some peace of mind lettin me know im doing the right thing.
Hello Stitch (and everyone else)...
I wanted to wait until I bought that pH meter before reporting back and asking any more questions, which I have done.
And this is the little experiment I am conducting:
I have 48 plants growing total (they are in 10" Azalea pots, btw, which is something you asked... they would probably be called "2 gallon containers", although we all know that they hold less than that.) They were vegged for a total of 2 weeks (after the cloning period of 2 weeks), and I have 1 per square foot on my tables.
6 of them I flushed tonight with 2 gallons per plant of H2O- I chose the least healthy looking ones for this part of the experiment. The overall runoff (I mixed all the water together and then took the pH) had a pH of 6.0. The initial pH of the water (which I had left for a few days in a large reservoir to come up to temp) was 6.4. My well water usually tests at around 6.0, so I wonder if the sitting has something to do with the rise? (and yes, the pH meter auto-compensates for temperature) (This is marked as "blue flag" in the photo)
6 of them I doubled up the nutrients I had been using and giving them their 2nd feeding in a row at this strength. The pH of the nutrient solution (which I didn't add any Cal/Mag to, as you suggested I should have enough in the soil with the lime I've added) was exactly 6.0. The runoff on the one I tested had a pH of 5.8. ("Green Flag" in the photo)
The rest I watered as per usual, although with perhaps a little more than usual, allowing quite a bit to run off for each plant. This represents the "feed every other watering" group. ("No flag" in the photo)
I'll update the photos in a week and see where we've gotten since then... there will probably be one more feeding for each set before then.
As far as the Pro Mix, when I didn't add any lime before, by the end of the grow my pH was reading 5.0 (granted, this was with the drop-based test kit, so it could have been anywhere between 4.6 and 5.4, in theory)...
Oh one more thing: my hydro guy definitely grows weed He doesn't know everything, but he has definitely been doing it a long time and has a very science-based approach to things. I (mostly) trust his judgement, although I still come to you guys for a second (and third and fourth...) opinion. I'll say it one more time: ICMAG ROCKS!!
So, with those pH's I've listed above, do you think I'm at least in the ballpark range of where things should be? I'm at week 5 in this grow- should I just lay off the Cal/Mag for the rest of the grow? Oh, and without using hydrated lime, if I wanted to adjust my soil pH, how should I do it? Should I just leave it alone for now? Should I NOT pH my nutrient solution with pH up? To around 6.3 or something?
Thanks again, Stitch!!

so no pics yet but more info, I had water prepared for a flush, but, the newer growth seems to be fairly fine but lacking in colour, so I decided I would just water until run off, roughly put 2 litres through the pot, the pH was 5.6, the water I put through the pot was atleast 5.9, in coco ive heard 5.8-6.2 is ideal, then again, ive been told not to even bother measuring run-off from coco, I took someones advice and have been watering daily for the last few days with plain ph'd water, the new growth seems to indicate that things are getting better but still have my worrys, few more days and if it seems to be recovering then ill slowly introduce nutes to it again, what ya think?
I will get those pics hopefully tomorrow.
oh i know what regular new growth looks like. i was talking about the tips of them. they look like they're showing some sort of deficiency as well as curling under. fresh new growth looks great thoughWhen you flush your plants out, unfortunately you also flush out the nutes with it so when you flush good you wash out nutes that was in the soil already so you end up having to feed before a certain date with how long your plants have been in the mixture.
LEaves will come out slightly discolored lighter green, once they are near full size it gets to the proper shade of green.
You have pictures of the newer growth?
Newer growth has a lack of green up to a certain point.... if they have fully 3 fingered leaves and still look very light; then it may be a problem.... without pictures it's very hard to determine it.
Yes, after they recover is when you reintroduce nutes; when you do start how low and very slowly work your way up.... pictures would help a ton if you could get them. People who say not to pH adjust all depends, because you would have to use the same type of nutes they are using and so forth; some strains are way more forgiving of accidents like overfert over water pH not stable and so on.....
Some are so picky where like just one thing is off and they fuss.
What is the pH of your water before you adjust it? because depending on what you use to pH adjust it can conflict in the soil.... have you watered with just plain un pH'd water and tested the results from the run off of the coco?
What brand of coco are you using?
Ya, when you let water sit out it will rise a little bit; with you having well water it goes through a filtration system.... kinda like RO water....
Those ranges are in the proper range, but you must keep them stable, the feed every other watering comment is correct
Your nutes could be bringing the pH down a bit and when you go and feed them they might not have used all the nutes up and when you feed more.... not to mention when you water as like you do you partialy flush the plants out so the plants don't sit in nutes as bad as it would have if the watering was not frequent.
I would keep the pH about 6.0 or slightly both ways......
I would most defiantly lay off the cal mag for now
Yes, leave it the way it is for now.
Depending on which nutrient you are using..... determines if or when you should pH adjust it; which nutrient are you speaking off that you use pH adjusters?
When you flush your plants out, unfortunately you also flush out the nutes with it so when you flush good you wash out nutes that was in the soil already so you end up having to feed before a certain date with how long your plants have been in the mixture.
LEaves will come out slightly discolored lighter green, once they are near full size it gets to the proper shade of green.
You have pictures of the newer growth?
my pH pre-adjusted is a solid 7.3 usually, I use vinegar to bring the pH down, usually takes 2-3 droplets, I havent tested run off from un ph'ed water, I will definetly get those pictures for you sometime today, its an iPhone im using so hopefully they will be good enough.
I'm using Canna Coco, thanks for your time its much appreciated.
Thanks again for your time, Stitch- I surely appreciate it.
Actually, funny you should mention that filtration thing- the guy who built my house didn't put a filter on the well water coming in- so it's probably pretty mineral-rich water (I've never had it tested, actually- probably should do that) I know there's SUPPOSED to be a filter... it comes out of the tap very tasty and drinkable, though!
As far as the last question, I guess I'm not sure what you mean. I mix all of the nutes together in a big 18 gallon Tupperware container with water, and the pH generally comes out around 6.0, no matter where I am in the regimen (I guess Fox Farm has them pH balanced? I don't know.) I had been bringing it up to 6.5-ish with pH Up, but you asked at one point why I was doing this. I just thought that was common practice was my answer- am I wrong in thinking this? Should I just leave the pH at 6.0?
Thanks

You do NOT want to use pH up, since you got lime already in the mixture and you using up your causing your pH to raise too much and you don't want that with using pro mix
Stay away from using the pH up. THat is ONLY needed for people who are having problems controlling there pH with different kind of nutes.
Also if I remember properly fox farm products can be alkaline...... which you don't want.
Do you use your mixture of nutes right away or let them sit out 24 hours before using them?
First stop using the pH up and get your water pH and ppm tested!
Stop adding a lot of lime, just a little; this is for future reference about the lime, cause you added the lime and what is done is done, only a good long flush would work; but it would take a while....
So first stop using the pH up, let the nutes sit out 24 hours before using them and get the tap tested
By the time you add the pH up which lasts..... and the mix of lime you added and the stuff that was in there you are raising your pH value high! This is why I said your pH looks unstable; up and down.
With pro mix you want to keep it around 6.0 or give a take a few.
and if your water is hard you are throwing in more pH up since hard water is alkaline, then with the lime added you got more micro nutes so it's high pH and too plentiful of micros which cause lockout of other nutes and unstable pH.
