They only get watered when the pots are dry to the touch and they don't get water on any sort of schedule. The water they do get is straight from the koi pond which most of the time gets a bladderwort and Irish moss seaweed tea. The medium is 80% nute less Pro-Mix with mycorrhizae with a bag of grow shop soil to stretch the Pro-Mix a bit. The temps are pretty steady at between 75 and 85 although they have bottomed out at 68 or 69 and spiked to 90.
The Timber Grow 3590's at 4500 are 15 inches off the Canopy which isn't the 18 thats recommended but Timber says it should be an issue but i can push them up a bit. They are only getting nutes at about half strength which has been increased slowly from 20% of what the manufacturer suggests.
I will back off the light a bit and I'll do a good flush. It's possible that the koi pond water has been affected by acid rain which can be a problem around here. Worth checking out.
All of these girls would have gotten the axe the first week or two but I didn't have the beans on hand to start over so I was just going for the ride anyway. I'm really most concerned with the 1 of 5 that has a prob I can't figure considering that they've all been treated the same.
The first couple of pics show the bad girl but what's her gripe with life?
