I have these plants in 2.5 gallon pots with ocean forest soil by fox farm I just started giving them nutrients about a week ago I water them every 3 days about 6 -4 liters between all nine plants the temperature of the tent stays around 71 degrees Fahrenheit and 36% humidity they have been yellow for 2 weeks now and I thought it was just nutrients deficiency at first now after giving them nutrients for a week and a half. I don’t know what it wrong with them if anybody could help me out that would be awesome this is my 2nd indoor grow I’m a noob and my last grow was autos so first time growing photo periods inside if you need more information just ask and thanks for the help.

Start by spraying some Epsom salts.
Did you use calmag? Looks like your ph is off and it's locking out some elements,
It's possible they are starved to the max. 7 weeks and you haven't fed them? The soil prob ran out after 3-4 weeks. Did you ph your feed? How much did you feed them and what
To me, it's looking like a calcium/magnesium issue possibly phosphorus. Like I said I'd start by spraying Epsom salts, and checking the ph of the medium.

What type of water are you using?

You should be adding Epsom salts to your water every time you feed or water them, at a rate of 1/2 teaspoon per gallon.

Mix some up and spray your plants at lights off for a couple days, and that should have them greening up again.

You starved them...they can recover with proper care, but the yield will suffer for sure. You also put too many plants in a single tent imo. I'd only do 4 in there. They're likely rootbound + hungry. But don't go crazy and start adding nutes + cal mag etc for soil, it's so overused and will actually cause more issues if anything. What nutes are you feeding and how much

Start by bringing your temperature up to 78-80. They look like then need fertilizer. My experience with FFOF soil is it runs out of pH buffer around week 7-8 and then the pH drops off a cliff. With FFOF you can get away without pHing your fert solution early on but it’s not good practice. You’ll pay for it later on.

They’re root bound and hungry. You can’t veg that long in small pots the roots out grow them. Pick a couple females transplant them into 7 or 10 gallon pots get them healthy and flip to flower.

Question for the seasoned growers.. which should help the OP at the same time.

Will spraying epsom at this point bring those leaves back to good health? I have never used epsom as a foliar spray. Only used once so far in my tent. Been in 1gal pots since dec 14th.678E0EC5-1555-43F8-8EEE-641AE06D3D9A.jpeg

If you're referring to the one in the lower middle, I don't think that's just a mag issue. The tips are starting to curl inward.

I see that you said that you're feeding them, but at what strength (seems pretty low). If you can, try to get humidity up and increase strength of food. Also, check into foliar feeding and feed them through the leaves as well until issue is corrected.
