Im growing all sorts of peppers, some tomatoes, cucumbers, melons and squash in rockwool and going to do a hydroponic drip system in a greenhouse. So far Ive seen slow growth due to probably alot of things but mostly me overwatering in the beginning I think. Im going to do 2 separate systems, one with lower concentration of neutrients for the peppers.

What can/should I do to optimize growth? Id love to see large plants and plenty of fruits of course. Topping? Removing early flowers?
