Took Drastic Measures Today
So this is what I decided to do.
First, I let my outdoor growing friends know that I’m not going to be able help them right now and to start germing seeds. I just can’t worry about them when my own grow isn’t under control.
The mothers haven't been showing any additional damage and I can see where tiny new leaves are just starting to work there way out after 5 days under the 400. All of them lost all the leaves on their bottoms halves.
I re-potted them all today. I did a root trim to about 6” square, all had very strong root bases. I kept only the healthiest branch of each plant attached to the root base and cut away all the others. I prepped the part of the stem that had lost all its leaves like it was a cutting, using
Clonex, and replanted into the ½ gallon buckets, burying the stem to the point where the green leaves start. I used only water today. When I start feeding I’ll start with ¼ strength
Earth Juice Grow and up it to full veg feed over the next 4 waterings. Tomorrow the light will be lowered to the proper level, still getting them use to the intensity after only being under the T5. I've been lowering it a bit each day since I put them in.
The way I figure it, those strong root bases will do better trying to make a small recovery than trying to work with a plant 12” tall that’s half dead. I have at least a month, maybe more, before any of the 30 cuttings will be ready for full veg, so I might as well fool around with the ½ dead mothers and see what I can accomplish. If I can get them going again I’ll go ahead and flower them and start new mothers from the cuttings.
Wish me luck, I’ll keep you posted.
