Ph help please
So everything with my grow was going great, then some tornadoes went through and I was without power for a bit, now my ph in my tank keeps jumping around and I'm getting lockout bad. I try to keep it between 5.8 and 6.2, I'll get it to 6.0, it will hold for a couple days, then it will drop to like 5.0, I'll dose it to 6 again and an hour later it's 5.5. There's a bunch of variables so I'll try to fill in everything I can below.
Light on, 84f/53% hum
Growing in 60/40 coco pearlized
Using RO water with ml per gallon balance, 1 ml gal CalMag
Using cropsalt as directed + .4ml gallon Runclean
Reservoir is 11g, I mix 10 gallons nutes roughly every 3 days. I'm mixing nutes in res by adding part A to the water, turning on a strong pump and letting it mix for 15-20 mins, then dump my part b in, add run clean and ph adjust. The pump is on a timer to run for 15 mins every hour.
I am using airdomes set to run when lights are on
There appears to be mycelium growing in my pots despite not using any additives
My biggest theories,
1.Mixing in the tank is causing nutes to bind and dropout, I should get a stir mixer, mix my nutes by adding them to a half gallon of water, then add that water to my reservoir
2.My Ro water, adding Cal Mag and Balance to try and buffer it, are throwing off the levels in the cropsalt
3.The air domes are the culprit. I have heard airstones can make your ph creep up, but can they also make it creep down?
Anyways, I'd love to hear some theories and feedback. I'm a longtime grower but new to autopots
