does heat matter

do they all look like that. are you feeding every watering. do you have any pics

iv got 5, each in 15 litre pots with 2inch of clay pebbles in the bottom then filled up with coco and a few pebbles on top to keep the coco from geting too hot, iv started giving them no more than half a litre with nutes every day, they all look a bit lime green but on some of them the realy small shooting leaves are a nice green
il put pics on when i find out how to do it plus im having trouble geting a good pic because of the lights

sounds like nute diff. bump up the nitregon a bit.

ok thanks il try bumping up the nutes and see what happens over the next few days
