Okay, I have noticed clawing and canoeing of leaves. Also, the Rockwool has dark green algae with some white stuff (I think its salt build up) and black spots. I have posted a couple pics, although not the best.
Now about the plants, nutes, and the setup:
They are 6 weeks old from clone (one week in flowering), ranging from 2-3 feet tall.
Using 8" Rockwool with a flood and drain system.
Watering twice a day for 3 minutes ( 1 hour after lights on and 4 hours before lights off. Was watering three times a day for 2 minutes. In veg, they were watered every 3 1/2 hours.
Under 750w HPS lamps with temps reaching 78-85. Heat fan set at 65 for lights out. 40% Humidity lights on.
Feeding them AN two part bloom at half strength, just added B-52. PPM 500. PH 5.5
Here are a couple pics. The Rockwool pic isnt great, but its dark green with some white and some black spots. Stems have had some purple for awhile.
Thanks
Edit: Is the ring in the rockwool around the stem normal?
I have a feeling alot of this from over watering
As for the ppm, I plan on slowly upping it daily to get it to about 800-950 for its current stage.
