Day 43 ph 6.0 ec 1.95 temp 67F. Plants rapidly drinking up the res.
Day 44 ph 6.1 ec 1.95 temp 66F. Added 3 gal top off of nute solution to res. New ph 5.8 ec 2.19
Day 45 ph 6.0 ec 1.96 temp 66F
Day 47 res change ph 5.7 ec 2.25
Day 49 ph 6.1 ec 2.05 temp 68F. Noticed I had a couple flyers in the tent, hung a yellow card and implemented UVB hung at 24" Currently doing 3 x 15 min reps at hours 4, 5, and 6 (mid cycle). Will add a 4th as they adjust to the uv. Looks like transition to budding is taking place. Today marks day 13 since 12/12 flip.
Cost of nutrients to date USD $6.19
@Med_in_Tropic, organic ph adjusting works well with soil, unfortunately from my experience with hydro, it's not as stable. It was shocking seeing GHE ph down per ML is more expensive than my base nutrients. Thanks for sharing 👍👊. Being able to meet and use local stuff is amazing. I finally got invited into a local circle of long time local growers (most have grown 10+ years).
Hi @Ga4rd2en0er, I am treating pH as an indicator not the underlying cause. Don't kill me. With my soil, I think not enough N and P will have too high pH.
To lower pH during Cal Mag addition, I addeed wood vinegar (pyroligneous acid). And around where I live, wood vinegar price is is reasonable and are made by farmer co-op's.
I have this thing. I try to buy from farmers and coop's. And this can unneccessarily complicate things for people.
@Med_in_Tropic, it's rather interesting to see where the greatest expense comes from and for me its ph down. Now I am searching for a better alternative. Thinking growmore ph down 30%
