Hey T, thats another great vid you made.. You plants are growing magicaly bro. And for only 3 weeks in very good for a 400.. And nice new camera you got there pics are looking yummy.! I can really see what you were talking about with the trichs...
Also got a few tips that might help you out..
probably the most important one is in bucket C I believe. the one with the currled leaves.. I think you said you already flushed that one of the salts right? if not might be a good idea. also you can lower the nutes in that bucket and that might help some..
Next I "wouldnt" raise the lights as you asked in fact I was thinking more along the lines on raising the 2 buckets in the front to even out the canopy..
And finally all those tiny buds and leaves that are withing 6"-8" or so from the bottom I would remove all of them now so that more energy will be put into your tops and good popcorns...
Other than that your looking golden.
Again much props for all your vids and what your giving back to the community with your bagseed vs breeders competition.. Nice to see a grower pay his respects to all the hard work that goes into breeding and to the others that grew befor you...
My man Tranc, thank you my friend..
