Could it be nute burn ?

Hey buddy! I wouldn't worry too much about the funny leaves. I use Fox Farm Soil and fertilizers exclusively and here is what I think: Over the last 6 mos, I have had 2 batches of FFOF and one of FFSF that came WAY hot. Burned plants for the first time in the many years I have been using it. I suspect that like all organizations, FoxFarm was effected by Covid. Maybe QC isn't up to par for a minute... Hope they fix it soon! You can mix some more Dolomite Lime into your hot bag of soil to act as a buffer. There is supposed to be Dolomite present already, but it will help to add a bit. My last Cherry Sumo had C-shaped leaves all through flower, but put out a great harvest of the finest smoke to come out of my garden in a minute. The hot soil should sort itself out over time. I would just pretend it wasn't there :P Happy Harvests bro they are looking fantastic!

Just light nothing major just hold back on the nutes since it’s a auto flower. I ran my auto in hhof by itself and it did good. Only nutes I would say add will be bloom nutes when you get to that time. Good luck

Im not saying theres any major issue here.. but FFOF is hot ass soil - then adding amendments on top of that in the first 30 days is a lot of excess nutrients in my opinion, and this is an auto so it can be more sensitive to nutes. There is some slight nutrient burn on the tips - nothing too concerning. I would let it ride with straight water for a week or so.. then asses the situation. You'll be good tho

That my friend is just new growth. Nothing to even worry about here

Hello you jave NO problem your plant is healthy and beautiful don't worry. Keep doing your great job.
