Help, possible PH issue??

[hdn155]

I'm a first time grower with 2 plants in flowering in my buddy's microgrow. They've been flowering for about 3 weeks and have been looking great until a few days ago. I used fox farms big bloom on them for the first time earlier this week and 2 days later they're completely wilted and the leaves are starting to die. I PH'd the water when I fed them as I usually do and followed the instructions on the fox farms bottle for the bloom so I'm not sure what I may have done to them. The kicker is, another friend of mine used the EXACT SAME WATER on his plants right after I fed mine and his plants look great. I flushed them yesterday when I noticed the problem and they just look worse today. Does anybody have any suggestions or ideas about what could be the issue?

Wilting is a sign of too much water or not enough. pH has to do with nutrient uptake. Post picture if you can.

that was my initial thought but i didn't feed them more or less than usual and they didn't get better, even as the soil dried out. Just took some pictures. I'll try and upload them now

Hi,

This is not a pH problem, this plant is severly underwatered !!

The brownish peak of the leaf is rather a nute burn.

Another bad point is that roots doesn't like light and your are ectually using plastic bottle as containers. In this connection did you dril them for water runoff ?

 

[hdn155]

Yes the botles are drilled and they have been used before in this same setup and the plants survived it. As for the underwatering, I've been feeding them regularly so unless they're just not drinking then I don't know thats the problem

transplant right away in dark colored containers! and clean that fuckin room up!

At the moment of the picture your soil was dry, wasn't it ?

About plastic bottle, I don't said that it where fatal but it is harmful for roots health...

I PH'd the water when I fed them as I usually do and followed the instructions on the fox farms bottle for the bloom so I'm not sure what I may have done to them.

This may be the problem. The dosage on any bottle, well almost any bottle, is TOO strong for marijuana. Me thinks you over fed them and burnt them up.
Next time use bigger and dark containers. You can get by with smaller containers when using coco but not with soil. They need the root space in soil and will become root bound causing you more problems.

what did you ph the water at? and never use the dosage on the bottle for such teeny plants. flush them throughly with plain ph water! 6.8 ph

Hey so this is my actual account. I was using my buddies while mine was in the activation queue. Anyways,
I did flush them with PHd water 2 days ago and just got home from work today and they're still in bad shape. The plant in the green bottle just to the left of mine in the first 3 pics were fed the same water, they are the same strain and from the same club. As for the transplanting, I'll see if i can come up on some darker bottles but the rest of the plants in the room are in the same type of bottles, so while it may not be helping the plants, i dont think its the source of the problem.

What kind of soil is that? The dirt looks way to solid in those clear cups which are a bit small. You need drainage through your soil, a new container and use about 1/4 the amount that is recommended by fox farm on the back, tiger bloom is HOT. You say last grow you did it this way and things survived lol....do you want buds or plants barley alive? Pack that room with 1 gallons, if you want more plants plant two in one pot, anything than those small clear cups.

ps are those huge rocks on top? Do you put rocks on top and rocks on bottom and solid soil in between?

haha, I noticed that perlite was a bit uneven (I swear I mixed in with the soil though) but the drainage has never been an issue and the soil doesn't retain water unusually long so I thought it wasn't an issue

why are people recommending ph of 6.8? after adding the flora nova to mine my ph is down under six. i added only enough ph up to get it to about 6.2 and they seemed to come back to life. mine didn't look like yours tho, they look dried out but who knows. you are ph.ing them AFTER you add the ferts, right? personally, i am using no soil and i think a ph of 6.8 is what was making my plants all look like crap. now they are all greener than hell. i am using about half a dose of the SeaGrow and about 900ppm of the flora nova. i also has started to give the plain water i give the ones about to be murdered ph of @ 6.3 or so too. i swear lower ph, at least with the organic compost or the 1/3 vermiculite/2/3 perlite, they just have been going apeshit since i started using lower ph

he used big bloom .01 .3 .7
how is it gonna burn the plant lol
its fox farms micro nute aka worm, bat and bird shit

hes obviously not using tiger bloom in early veg

[libby]

Those plants look wet and polsened,(my letter "eye" ls knackered ) get them ln cleaner solL, and don't feed tlLL they ask for lt.

Repot into bigger containers of good, fresh soil with at least 10% perlite thoroughly mixed in.

Water them with a very mild nute solution and give the roots a few days to spread out, then resume your normal watering schedule.
