3.5 week old seedlings.Transplanted my rockwool cubes into clay pebbles after roots were popping out maybe an inch from bottom.put top feed on 15 mins on 15 mins off feeding,half strength nutes( built up over two weeks ) reservoir temp 64.5f,tent temp 20-25c,outtake fan on with a gap in tent door drawing in fresh air, fan on low to circulate air (gentle breeze on plants),nutes at 0.8 on my meter-recommended? Went from 24/7 fluorescents to 24/7 600w 2 ft away(no heat on hand that close) After day one 1 was drooping now day two and another is drooping. When the first went I put on constant watering now the second is going I'm gonna shut off the top feed and see what happens.
Day 1 after transplant,bottom left went first....this is a photo of a picture on my phone,sorry about the quality.
