Oh, and this time I used the PHDown bottled phosphoric acid, instead of the white distilled vinegar I'd been using. So far it doesn't seem any different. Latest ph test (9:30 p.m.) was 7.71, after starting (3:00 p.m.) at 5.4. One 10-minute trickle feeding at 6 p.m. Gotta be the airstone...
I'm try to figure out why the air stones would affect the ph. I have heard if you run co2 and air stone that it can be a problem from the co2 filtering into the water but that I've heard about it.
Yeah, found that idea, but doesn't apply here. What I CAN'T find is any science behind the airstone-is-to-blame theory - so far...
Turn up the trickle bro. the secret is in my signature. The power is in the flow. Thank you. Once you have turned up the flow you can dial in your nutes with a good flow 2.0 EC is easily achievable
So what's your advice, 24/7
pumps on 24/7 for sure the flow protects from nutrient burn. nutrient burn happens on ebb as water evaporates/plant uses.
Interesting, I will keep that in mind. Thanks for your input.
So, apparently we're by the ph issues - it's now steady, to trending DOWN.
Awesome, looking good brother. Did you ever find out what the ph swing was caused by.
Nah, I DID change from white vinegar to the Ph Down product, which seems to be more concentrated acid, but...? I'm now at 2/3 suggested nute level (vs. Jack's 3-2-1 recs) - and I went from 6X10 mins per day to 6X15 mins.
Thanks, I like to top and bend A LOT - which is tough with hydo (I'm thinking about mods, lol) - and the whole tent MUST be on the same schedule, pretty much. I learned to HATE top-watering (gnats), so everything I do is in search of avoiding it. Maybe too much, lol...
Ive never had gnat problems fingers crossed lol, what type of lights are you running?
I started with an HLG65 (65w) that came with my first tent. That worked for my first 2 plants, with a lot of turning to expose all the buds. So I upgraded to a Mars TS1000 (165w) and was tooling along fine - then the gnats hit. Decided I'd try hydro (anti-gnat plan) but needed a larger tent, so I got a Mars TSW2000 (300w), which I'm using in my original tent for flowering - and it's FANtastic. The 1000 is in the meter square hydro tent (already planning to get another 2000), and the HLG is in my half-closet "nursery".
Progress of hydro & what's flowering...
I’m about to be doing the opposite... setting up a rdwc and incorporating a drip line to each site to top feed for very early stage where the roots won’t be long enough to reach into the nutrient solution below
Not sure how thats the opposite but sounds good man.
Start of flowering week 8. Buds fattening nicely, trichome-rich - even some fan leaves. Planning a few small improvements & have 3 GSC clones rooting for Effort #2.
I have a theory about the ph thing. I rinsed the perlite in straight ph 8.0 well water before using it & I think the perlite needed to flush that high-ph retained water out before the ph settled down closer to what the res was sending it. After a few weeks it settled down to 6.0-6.2 and hasn't varied much...
