inward upcurling and burning tips 3 weeks into flowering HELP.

i have in my flowering closet 2 mother plants. both undefined indica/sativa hybrids (70%-30%). i have one that is flourishing beautifully, with tons of thick pistols, and nice resin coverd calyxs.

but my secon plant in the closet has pretty much stopped growth and the sides of the leaves have curled almost closed on newer fan leaves and higher branch leaves, with burned leave tips that have turned grey and pretty much died.


i know this should be in problems and cures but i really need some input.

it wouldnt go unappreciated.

i almost have the same problem, my plants are getting yellow tips and its only getting worst,but they arent turning grey are dying just a little burnt tips. i thought it was heat but i pulled it away from light and it continued.

i have flushed the soil.

and tried lowering and raising the doseage of FF tiger bloom i give that plant.

and also transplanted into fresh soil.
