Got a few successful grow with coco and supersoil all DIY nutes/soil but right now on my first attempt at DWC. Everything went super smooth with my 60 gal 4 plants RDWC, chiller, AC, mix of COB-QB Led totalling 1200W, automated ph control with industrial grade ph controller and DIY nutes. Totally out of my expectations but I got uncontrollable growth and leaves bigger than my hand during veg, never in my grow room to see anything denser and wider than that, I was super stoked and totally sold on the idea of DWC.
Problem started when I switch to flowering, just all of a sudden the girls just cannot take any amount of nutes higher than 0.5 EC where previously during peak veg they took 1.5 EC comfortably with no burn. They all still drinks a lot, like 5 gallons a day sometimes slightly more. Considering all other aspects are definitely spot on without any doubt, I naturally suspected my DIY nutes and began mucking around with the formula for 10 weeks!!!! Just call me an idiot because I am, at least mixed 20 different formulas for 10 weeks to no avail. Off course the flower cannot wait and they keep on growing and maturing albeit very slowly and small buds. The structure of the growth nodes are definitely fat and perfect but the actual flowers are small, all are the size of lower tops (one size above pop corn buds) on normal grow but I can definitely tell they also being delayed so much on maturing. The color are all still very fresh green, a bit of white hair still visible showing up, under microscope its still 60-70% clear, leaves are still lighter shade of green with no visible rapid yellowing, now at week 12 of flowering and strain is Blue Dream. Previous grow on super soil was same strain and fully matured ready to cut in 10 weeks, it was insanely potent.
I finally gave up my multiple attempts on different nute mixes and out of nowhere by buddy just said "hey maybe it's lack of Co2"....I immediately dismissed his idea due to the fact that this particular buddy have a habit of spewing out nonsense and all my previous grows was perfect with same setup sans DWC. He argued that this time the plants are much bigger and my room is still almost fully sealed with no exhaust. Fortunately I was willing to try anyway and turned out it was exactly that, too low level of Co2!!! Immediately after addition of Co2 from a bottle, suddenly all the girls are hungry too....
Big question is... Do I still have a good chance to fatten up the buds considerably? What's the best strategy to boost the girth, density and weight with my situation?
TIA!!
