Hello, I have a problem. My seedlings are not developing and keep dying and I do not know why. Growing conditions: Room temperature: 20-23 Celsius Water temperature: 21-22 Celsius Room humidity: 50%-70% Lighting: one 600w Agro lamp set at about 3 feet from the plants EC: 0.3-0.4 pH: 5.8-6.1 Growing medium: rockwool Water change every 7 days Air pump: on Strains: OG Kush, Purple Bud and Malawi I kept the seedlings 6 days after they sprouted in a cloning machine (without the water running) under a humidity dome. After these 6 days, I moved them in my aero/nft system and since then 3 weeks have passed and they haven't grown at all and now many of them have almost died. The tiny leaves slowly started curving down and dry up. Did I maybe move them to fast in the system? What do you think is the right time to move them into the system (height, nodes, etc.)? Did I give them nutrients to fast (6 days old)? What EC would you recommend for young seedlings (1-2 weeks old) when using an aero system? If I'm using a humidity dome, how long should I keep it on after they sprout? To keep the right humidity inside the growing space I have to spray water in it. I also sprayed the seedlings. Is this bad? Can this negatively affect them (thermic shock)? PS: I moved the seedlings back into the cloning machine, under a humidity dome.
