Poor man's aero grow

Hello and thank you for taking the time to read me. This is gonna be the last update before the harvest in a week and half, or so. I don't see the point of doing 2 that close, i'm not doing much anymore nor i have much to say. The plant on the left would have needed a different feeding too, she was still bulking up until very recently, and i started from clones. This pheno and under these growing conditions should be close to 70 - 77 days. I could chop her sis this week but the smoke would, imo, still be too harsh. About the smells ; nothing much to say except that it now stinks. It didn't change much over the last weeks. The kushy plant now smells like skunk, lemon and gas while the cookie pheno smells like lemon, cream and hints of kush. I can't manage the ph anymore, it drops from 2 points every day. I tried adding calcium (there must be carbonate in mine) but it didn't change anything so i just let the plant empty the reservoir, then i'll top it today or tomorrow with a lot of RO then give up on the ph, it should be below 0.5. Or i might just top it with tap water. Although I did a few grow for comparison and even if the conductivity here isn't bad, i always had better results elsewhere. But the Ca def, then the iron def, then again a small Ca def on the left plus now the ph swinging, i might just get less headache by using the simple faucet... And in a week or two, i can't be sure of it tho, the chelate levels in my solution should be low enough to be safely dumped in the tub. See you at the harvest! (I'm debating with myself if i should use the tumble trimmer or not. On 1 side, i suck at it and i don't want to spend a week trimming, on the other one, it would def be a pity with this bag appeal.)
