Hello,
I had 5 seedlings going good, but then their growth stalled and has come to a stop for a week. Leaves are turning brown, the plants just don't look good. They were just opening the first set of true leaves. I'm trying to pinpoint what caused this.
I had them in rockwool cubes, without plastic wrapping around them, and not in a tray. They were getting light through a window until they broke through, then had two 23-watt CFL's and two 13-watt CFLs on them for about 18 hours a day. They were getting rainwater when the cubes felt very light. I would dip the cubes 1/4 the way into water and let them soak up for 10 seconds.
What is the most likely thing that caused the plants to stop? I'm thinking:
- not enough light
- maybe the cubes dried out too fast without any wrapping. Maybe I didn't let the cubes get quite dry enough.
- lack of nutrients in the rockwool and rainwater
- plants got a little too close to CFL's
Any help will get +REP
