hey peeps this is my first grow i am into wk 2 veg growing 8 shining silver haze plants which is an indica strain that grows to approx 90cm i have a couple of problems that i would be very grateful of some advice from experienced NFT growers.i will go through my set up first so here goes i have a proper 1.2 x 1.2 x 2.0 growtent with carbon filter n extracter fan. my bulb is 600watt hps with aluminium light reflecter with two 6in fans either side all on ezi rolls for ease. my tank is 40 litre cap with water pump i have also an air pump with 2 6in air stones either side of pump. my general stats are PH 5.8 to 6.2, EC is 1.6 to 1.8 ,humidity is 35% to 60% and temps is 65f to 91f at the mo i'm only using canna aqua vega for nutes until flowering stage.
so for my problems my leaves are droopy and curling upwards and i noticed today that i have discolouration to 1 leaf on 1 plant out of 8 plant some other leaves look quite dry n dark green others look lush i'm not sure if its my humidty and temps swings causing this or my ph an ec levels any help would be much appreciated
