Hey man,
The leaves wilting combined with the yellow spots I'm seeing in your photos is making me think your plants have a magnesium deficiency.
If you're just using biobizz + canna calcium like it says, that's the most likely explanation.
Easiest way to fix it is to add some epsom salt (magnesium sulphate)!
Cheers!
@Liberty90, thanks :)
Well, 1 Fan at the bottom for intake and a total of 3 fans at the top to suck air out and have negative pressure inside.
Don't need the airflow for cooling because LEDs don't create much heat. So not sure where i would be missing.
@LoveDispenser, A lot! Cola's started spouting like crazy. I kept around 20 nugs I think. But they aren't giant. Yield was around an ounce, but the butter should turn out great. There where quite a few really tiny colas that I simply left with the trimmings.
Reasonably happy with the result. :)
