OK I thought this the other night but been keeping and eye on it and tonight when I went in there I saw it again........
Thick leaves. The last time I had this it was because of the ph was way off. So right away I grab the calibration crap and the test pen, Calibrated it and tested the water.... Well the ph was fine, so I have moved the water lines back from the plant a bit just in case of over watering. oh well will see.
Here is a top pic of them you can almost see the
thickness

A bit of info
the ph was 5.5
Hydro
4x4' 40w flos
any ideas on what it could be ??
Here is what I feed them tonight
and now a question....What would happen if I vegged with 1 of my 600w hps ?? I have more of the flos I used last time when they got big enough.
What would be the best without buying a MH, and using what I have ??
My other strain is doing fine. That strain is Top 44. they have been watered from the same tank
here is a pic of them
Both strains germed at the same time
