So I am growing 25 plants. Its great white shark auto, and I am using HPS 600w and i m growing from seedlings. First about watering. I have placed germinated seeds 72 h ago in the soil and the soil was quite dry so i poured 2dl of water over each 6L pot. and then maybe another dl over the period of these three days. The soil feels moist(not too moist though) as soon as you stick finger over an inch. I guess i am not over or underwatering them... The seedlings started to appear after good 24h and by 72nd hour all of them were out. Whats wierd is that few seedlings appeared with only one cotyledone?? and one seedling is showing signs of yellowing (one of the cotyledone-they r supposed to die off rignt?) The PH of the water is more or less 6.5 and that of the soil is 5.5 - 6. I am using plagron growmix terra soil.
Second thing i wanted to ask is about hps i am using. The first two days they were over 1 meter away, as of today i have them at 80cm and the temps get to around 27.5c max. The lights are 24/0 which i changed today to 20/4 so they get some rest. How should i go about lowering the lights further? 5-10cm a day?
My third and finak question is what do you think by looking at the pictures? Do seedlings look healthy to you or am i about to get a loss of my life(they are everything to me hehe) One more info, the temps in the room are from 22 to 27celsius, humidity 33%-50%; avering 40% ( i m a bit worried about having too low humdity levels). And i have air exhaust and air inlets for fresh air from another room. I also use two ventilator fans.
