First time growing, leaves are curling under (in the last 5 days). Don't think it's deficiency got premixed soil says good for 9 months, its been about 8-9 weeks. wondering if maybe too many nutrients or overwatering. didn't want to flush roots in case too much water is the problem. plants aren't under any lights, they are growing naturally in pots with plenty of sunlight. please help! just the tip on the very end of the leafs are turning brown tried to get that in the 2nd pic.
