Weed plant problem, please help

What is the EC of your water? How do you decide it needs watering? When watering, how much water do you give them? When you started this grow, did you use an part larger pot from the start than needed?
 
Lockout from overferting. Check pH of your runoff. If its low your feeding to much/to often. You could also check EC of your runoff to get a final verdict.

Just give it water and it will bounce back. You probably got EC value way over 4.0 in the medium
 
This is nute burn. Raise your ph and lower your nute dose. Don't use more than the lowest recommended dose with fox farm products. Go plain water for a time or 2 for now.

Exactly what I was going to say. You need to check your waters ppm/EC, as Using Fox Farms bottle recommendations can put you well above 2000 ppm, while realistically, you should be around 600-700ish depending on your Starting water. Checking the run off of soil isn’t as important, but you should absolutely give a few plain water feeding ph to 6.5, then get your ppm down to around 650ish and go from there. Its not likely you need a cal-mag supplement, but a good shot of some mycorrhizae rich compost tea would be a great idea after a few plain watering seeds to Get your healthy bacteria back on track. Best of luck.

Word appreciate it, how do I measure doew ppm?

My ph runs at a 7.5 what's that mean?

That you probably use organic nutrients and/or additives. Just give it water and time. If your tap is 7.5 adjust it to 6.5 and water with that.

Edit. Just read you used Lemon juice to adjust pH. Lemon juice will convert and become alkaline when broken down, raising pH

How should I adjust it, tried to use lemon juice. That's what has seem to make worse

This is a downside using nute lines designed for RO water, in dirt there's other alternatives. But RO water will have less chemical disturbances and be more sterile. Phosphoric acid is best or citric acid as a last resort. If you're a chemist maybe you got hold of sulphuric acid, LOL :lol: .

Just buy pH down. 25% strength is really easy to use. Or buy the most concentrated and make your own solution.

I agree, nute burn is causing the problem. And please don't say you have a 2000 watt light. 2000 watts would light your tent on fire. What light -exactly- do you have?
 
Looks like too nutrient burn to me too. IME, use 1/4 to 1/2 of the FF feed charts or you'll burn the leaves. Like someone said, the FF feed chart calls for super high EC / PPM. Not sure how Fox Farms expects any plant to grow well with their feed schedule.
