I was expecting these panels would hit the 2 oz per plant mark before you ran into issues. I totally suspect the deficiencies were the main culprits here so I wouldn't be worrying about the lights being bad. I honestly wasnt sure what kind of yield you were going to get after that went down, but your results are still good. Lowering the lights will likely help too. I'm sure your next round will be on par with my expectations for these lights.
The last strain I did 2 oz per with was snow dream (journaled here in riu), it's a cross of snow white x blue dream. I usually do 2 plants under the 180, anymore and I have to do smaller plants or my yields decrease. Two seems to be the right number, I veg for a week or two til clones are about 20 inches tall then flip.
Nice! Ya, I am excited to see how round 2 differs with the correcting of nutes and a few new factors that changed:
Instead of 3 gallon plastic pots, round 2 is in 5 gal smart pots.
Lights are now 50" from floor instead of 55"
Today is day 7 of round 2.. I'll get some pics up shortly!
