Guys help please can't figure out what's going on with my 6 girls. Ever since flowering they've gotten very brown on old growth and appear to be dying. I've only given then megacrop twice and PhD water to 6.5 every 3 days.

My condolences, those are some sad looking girls. I'm curious where you went wrong. The soil looks like Pro mix or something similar. You're PH ing your water, does that mean you water every 3 days? That would be pretty normal. How much Megacrop did you give them? I have never tried MC in Pro Mix but i would assume it would be fine. The stuff is pretty potent. I only use around 1/2 tsp/gal in hydro and I would probably water soilless at the same strength. I'm guessing it must have been too much Megacrop.

If your soiless and only fed twice they are probably starven. You need mutch more info for good reliable help. How long from flip? How mutch did you feed. They look hungry but the last pic it could be extreme deficiency or burn. I will say this. Soiless should be treated as hydro and your ph should be closer to 5.8

I call bullshit on the pH thing, 6.5 is fine, even in most hydro, depending on your nutrients’ specific composition. I run hydro in coco media and RDWC at pH 6.5-6.8 for whole runs, it does fine.it mostly depends on what sort of iron chelates are present in your nutes. EDTA, DTPA or that other one, lol.

OP your plants look sort of hungry, to me. Are you in soil or an organic material based media of some sort?

I don't know much about soil but I thought the same thing. They look hungry. P or K maybe. OP, these guys know what they are talking about, so listen to them. You are gonna start to see it up top if you do not do something.

I agree with the second poster - it sounds like you over watered you state that you water every three days but only fed twice.and when you feed the plant it was way too hot is what it looks like and burnt them up. Probably have a weak light too so nothing is really happening as far as the ability to grow out of it. Not much info to go on other than been there dont that.

so I think soil too hot with root issues so my suggestion would be to flush really good and renute with a lower ppm and definitely get microbes in there and leave it alone till it needs to be watered again.

Soil, hlg lights at 480 watts. Should I use mega crop again or get different nutes for bloom.

Two plants had burnt tips to start and have progress to this with light green color and dead leaves. From the articles really looked like nitrogen to hot as I got the claw.

Was running happy frog on top and ffof on bottom. Mixed with extra perlite. Used megacrops chart and did 10grams and got a ppm of 300 over base of 70 from the tap after it sat to get to room temp.

Memphisto seeds 3 different strains.

Water pretty much every 3 days now till the saucers are full then vac out the excess. Smart pots 3 gal.

What distance between light and plants?

Nit tox isnt the only thing that causes clawing and nit tox comes with super dark green and waxy leaves. Also megacrop dosnt use urea derived nit. So it is much harder to burn plants with it. My feeding tops out at 8 grams per gal megacrop 1 tsp per gal g-10 and a tsp per gal of purple max. Im in 50% coco/ffof and feed with every watering.

feed them. i'm not sure if that's a deficiency or a lockout, but it should be a deficiency if your information is accurate. give them the megacrop at 3/4 strength a couple of feeds, see how they like it, then either bump it up or down. and a foliar spray with epsom salts wouldn't hurt, either, i think
