Durban poison and green crack

Things are started to get some size to the buds. I upped the nutes PPM this week to 1050. The durban clearly has awhile longer to go while the green crack looks like it might be done sooner then later. I'm debating giving green crack it's first overdrive feeding next week.. we will see how the buds are looking then.. I used to feed a week earlier then I should have so I'm trying not to get too ancy with it yet. Both look great.. some slight light burn so the light went from 100% to 80%... just put up to 90% to see how it reacts.. if any issue I'll go back to 80%.. that might be the most it can handle at 18 inches at this point. Gave a heavy defoliation to both plants tonight after nutrient freeding. I defoliated more of the top leaves to expose more bud sites. Then I defoliated the bottom buds sites that I know won't amount to anything and the twig branches coming from the bottom that don't get any light neither. Took 3 hours to get it all accomplished.. forgot to take before and after pics but both plants were monsters.. not much light could really get thru the top canopy Now light gets thru the entire plant so the lower buds are exposed to light and better air flow for sure. My final defoliation will be 1.5 weeks before harvest.. pretty much at the point I start to consider beginning my flush. That way it will fatten up the buds and help finish the buds that haven't been getting much light. Excited to see the final results.. this my first time really doing a heavy defoliation throughout a plants entire life cycle. It defintely helps final yield if done correctly from what I've seen. I figured I'd give it a try and see how it goes.. so far I'm satisfied with the results.
