Since the plants started going downhill this is what been going on.
We are using G.H. for nutes at half strength of there feeding schedule that they provide.
The last week no nuts just 6.0 ph water at room temp to flush so we could "start over"
2 days ago we treated the plants with gognats, while all this has been snowballing out of control. We have been watering by hand not with the drip system, one time a day until it runs out of the rockwool.
plants are 7 weeks old they are from clone the strains are blue dream and la confidential
The room temp is 75 with the lights on 65 while they are off humidity 40-55 %
Im sorry to say but we did not condition the cubes.
covering the medium ? I dont even know what to use or heard of that before
there are plenty of roots comming out the bottom of the cubes.
there are 2 4x8 tables with 4 1000 watt lights 18 inches above the plants.
So i have 45 plants that are ok i use the term lightly and 30 that are not looking good.
any help is awesome ! what would you guys do to get these guys back on track .
