Very nice, what nutrients are you running in your aero grow? I've really struggled since switching from dwc, thinking something is off with my methodology at this point.
This is LPA, so glorified DWC, but I’m running Advanced Nutrients. I was having some issues myself as I switched lines over midgrow from Technaflora.
There are some specific things you should avoid in Aero since they can clog, humic/fumic it’s one of those, but what issues are you having maybe I can help?
My timing is 5 minutes off and spraying for 30 seconds.
Here’s an old build album, has the old line I was using though. Linky
I use the same by happenstance, and have for many grows with my old setup. The biggest issue I was getting is nitrogen abundance, clawing, etc., while seeing obvious signs of calcium/magnesium deficiency at the same time. I would frequently get nutrient burn, but even dialing my res back 10% would result in pink stems (phosphorus deficiency).
I mostly have things stable now, but the damage is done, it looks terrible.. but it's massive so I got that goin for me I guess.
Anyway, ultimately I changed how I was topping up my reservoir and things seem better, I am just not sure if I should try something else or not on the next run.
What recipe are you following? I went full board for the masters line and using the ph perfect 3 part.
So I noticed with this line I couldn’t just top up my reservoir like the other one, this time I’ve been emptying the reservoir and making a brand new batch each week, but I think I need to up my strength a hair.
I fill my bucket up with 25l and make the recipe for 20l, I was doing this with my old line, so just carried through. I check ph and ec every morning and adjust Ph if needed. 3-4 days later I usually need to add 20l tap water as there’s not enough water for the pump, sometimes I need to do it again the day before I change the res. If the EC is creeping up I add tap water earlier.
I have been using their two part connoisseur line for a while now, and it's generally set and forget. I would refill my bucket back up each morning to the same level, but didn't have to bother with ph, etc., and do a full replacement every 4 days or so. I tried that with aero at first and would quickly see deficiency signs, so then I tried just letting it run down and replacing res when it's low, but that resulted in crazy excess.
I added some additional lighting, which is helping it chew through more food, but the biggest change was refilling my ras back to roughly the same tds values a couple times a day, instead of once a day with a preset volume.
I am surprised you are PH'ing your water while running the ph perfect line. Does that have to do with running the full masters track? I didn't really have luck moving the needle the few times I've tried.
From my understanding, and the marketing propaganda, the surfactants and chelation make everything available for uptake as long as the range is > 4 and < 8ish. I genuinely stopped years ago, but I do miss the control sometimes.
Hrmm yeah that’s out of my knowledge, I’ve been having less issues as they filled out the tent.
I probably don’t need too, but they say to get it in a range of 5.8-6.2, so when it’s 6.5 I throw a little in. We do have really hard water (mountain/glacier runoff) and have a softener too. If things get worse I may look at getting RO water or even a system, but things seem ti have settled out. I’ve been hardly phing lately, but I’m still getting some issues, which is what’s leading me to the slightly imperfect PH.
Yeah I may just try not adjusting it unless it gets wild out, but that’s why we experiment and try things.
