hi, this is my first grow and both my first 2 plants have problems. the first is a deformed plant, and has brown blotches on the leaves, and the second is a seedling which at one point fell over and wasnt noticed till morning. it seemed to have pulled thru but today a grey type of fungus has sprung up on the outer part of the first nettle leaves. also the leaves have curled up. im not sure if its fungus r what as i have no experience with growing :( there under a 400 hps at 24inches, in a room 3x3x7. humid is at 55 and temp 80-88f. just being fed water, altho i did flush soil 1 with 1/4 strength nutrient. ph is 6.5 for soil and 5.8-6.0 with rockwool. any help wud be greatly apprecieated. thanks
