It seems I'm still getting the floppy leaves and such with the new growth once it gets big. I'm starting to wonder if I'm overwatering them or not? I'm doing 30 minutes at a time 4 times a day, last watering ends at 9PM. I'm going to make a post in the hydroponics section to see if any e&f growers may know. Or if you are a e&f grower and using rockwool cubes you can answer here too
