Friend ruined my plants, what can I do ?

Yes its my active diary, they both have damage but this one is the worst. Thanks guys, I'll flush them both tomorrow & put a feed through with the second bottle & keep my fingers crossed they recover .

monitor your situation and use the tools available at your disposable. If you have a PH pen or strips as well as a EC pen you can figure out whats happening. You have one active diary so I will assume this is from that diary, Its an autoflower, the light can be stressful, but it will not cause it to reveg. So manage the feeding concentrations and deficiencies or lockouts you maybe experiencing to return it back to normal and continue from there. Tell your friend thanks for the help and that if they need anything ever to let you know, then you can shit on their toothbrush lol. Good Luck!

if you ever have moldy weed, make sure to give some to that specific friend as a gift... hope it is an autoflower... or else you have to worry about a re-vege. if it re-veges it's going to turn into a fucking mess.. no exaggeration. stems will grow again, funky leaves will pop, whatever bud development you had will turn into stretched out popcorn. an insane amount of axillary growth (side branches) will make it a congested mess.. you'll have to prun some off for sure it's so bad. hope that doesn't happen... time will tell. You are low on N from what i see. Possibly low on K too. i've never used a 1-2-3 ratio and my plants look healthy all the way till the end -- limited senescence is always expected of course. sometimes it is avoided but they often have small issues at end of life even if properly fed. it's too early to have the issues you have, so review how you have fed it the last month and currently.. formulate a new plant next cycle - see how it goes and eventually you hone a method that works consistently. plants are not nearly esoteric as most beleive.. that's the result of odd formulas that might work for a few plants but not many. a good nutrient formula should work for 95% of any pot plant you grow. that's a good formula.

Is this light burn, over feeding, ph or all three ? I'm gutted . Do I feed tomorrow or flush ? Advice please 🙏
