Bigg Al's girls look sick

[Bigg Al]

Hey all,

I came home to the girls not looking good. I think its mag. But cant tell. I did a semi flush yesterday. The 1gallon pot got 1 gallon and the 3 gallon got 1 gallon, but idk

The top 2 are BB#1 in the 1 gallon pot

The bottom 2 are BB#2. I've only gave the water with cal/mag, no nutes yet.

Soil is ffof/pro-mix warm casting. Rh 57 temps 79-82

Rain water, pH @ 6.3

Any advice will help!

Looks like N toxicity to me buddy! Appears your soil is too hot. If it were me I would give it another flush but wait for a second opinion before doing anything drastic as I'm not the sharpest tool in the shed sometimes

Al-- I think something is TARFU with that soil, pH likely...and the main suspect is that damn OF soil, even cut with Pro-mix,....(hearing about some dicey bags of that as well... bad batches can happen!) But soils are dubious at best IMO, the [HASHTAG]#1[/HASHTAG] problem soil I see here (OF mainly), usually badly acidic,.... I recommend getting a soil pH probe, the Accurate 8 is a good unit for the $, otherwise it's a more $$ unit like Blue Labs probe...
This happened suddenly, right? Hmmmmm.... well do you have some of that soil blend still? You can do a slurry test with it if you do. Take 1 cup soil, and about 1.5 cups of low ppm water (RO, Di), mix up and let sit, stirring occasionally for a half hour or so... drian off liquid and test with a pH meter, make sure that's calibrated BTW.... this might offer a clue,...
What's your light set-up, distances, type etc?

I've never had this problem before? I do have a soil probe I'll check with that. Lights are auto cob @ 22 Inches away

Thanks

I’m a total noob, but 22” away for an autocob seems close to me. I’ve got mine parked 36” away, but I probably need to move them closer.

Here’s what someone gave me:

I'd hit her with a tablespoon of Epsom salt per gallon water, looks plenty wet so you may want to foilier feed until she needs watered again, you will see some greening up in a couple days, I agree with everyone here is inconsistent swore that stuff off a few years ago, too many nute lockout issues,

Your in good hands now, i'm a new guy to, my COB's are at about 28" at 6 wk's of flower. I will never use ffof soil again, I've had nothing but problems with that stuff--- looks like it's burning your little girls.

I am in veg so 22" isn't so close as it say 24-30. I've been using ffof for all 12 plants that I did so far. This is the only grow that I'm having this problem. My other 2 that's going now is in roots Organic, the glueberry was water with the same water and she is doing fine. I'm just a little pissed that this is happening while I'm in the big grow battle. I might just pull out of it.

I'll do that when I get home. I was thinking of doing it anyway but needed some advice b4 I do it.
