Leaves curling upwards and brown spots 10 week autoflower

Hey, I saw your diary and you feed waaay too much. Cut the dose proposed in half, I’m using the same nutes (biobizz) and I had my first 2 plants burnt because I was feeding like you. Always remember, less is more in this case.

Looks like nutrients burn, have you been checking out your run off? Make sure you re on the right level, depending on the week your plant is at you should pay atenttion on to how much nutes you use on the water you use to feed them, if nutes are alright then you should check your PH, something tells me it has to do more with the way you're feeding them, have you try to flush them and lowering the PPM? Place multiple fans so you get air flow and if by any chance you are overwatering fans will help you drain the excess, another tip brother make sure you touch the soil and if is still cold or wet then you do not need to add water until is actually getting dry or your soil is changing color alright hope this helps
