New growth looks weak

[Guest]

12/12 x2 weeks. Just starting to flower. Vertical growth has slowed/stopped. New leaves are limp and curled. Runoff ph is fine. Plants look very healthy otherwise. Had just a few gnats so I let the soil dry out a lot. Just watered to 20% runoff. Could it just be a water issue? Seems like it’s something more than that though.

There could be (I am not saying there are) fungus gnat larvae feeding on your roots. You can buy expensive insecticide to kill the sonsabitches off, but I use hydrogen peroxide mixed with water 1 part hydrogen peroxide to 4 parts water. It'll make them fizz right out of existence. :hard-laugh::hard-laugh::hard-laugh: http://freeplants.com/fungus-gnats.htm

I only saw 2 gnats. I had to flush like 3 weeks ago and I don’t think the bottom of the pot ever dried out very well. Watered again because soil 3” down was bone dry. Fungus sounds likely. I don’t think there are enough gnats to be the cause but I could be wrong. Does HP work for other kinds of fungus or just the gnat larvae?

I think overwatering is at least part of the problem. Since I flushed ~3 weeks ago the bottom 1/3 of the pot hasn’t dried out. I waited till the soil was bone dry on the top two inches and watered but I watered to runoff. Did the same thing today and now they’re very droopy.
