Day 8 (Friday 11/13/2020): I need to figure out what causes Ph fluctuations. The water was perfect going in last week, but I checked it before changing it, and the Ph had gone all the way up to 7.2! Later on in the grow I assume the plants themselves affect the Ph, but I can’t imagine three little seedlings could alter things that much??
This week we’re starting out at 5.72 Ph / 473ppm. I added less FloraMicro than I have in my past 2 grows, since N toxicity seems to be a recurring problem.
Day 9 (Saturday 11/14/2020) It’s getting really dry now that it’s cold out and the radiators are on. I’ve ordered a small humidifier.
Day 10: (Sunday 11/15/2020): SO DRY. I keep misting the room with a spray bottle, but it doesn’t help much.
And the Ph is up to 7 again! Added half a capful of Ph down. The ppm is down, so they got their nutrients at least. I’m adding a 1 gallon water reservoir, so hopefully keeping the water level steady will prevent the spike going forward.
Day 14 (Thursday 11/19/20): the ph only went from 5.6 to 6, so the addition of the reservoir seems to have helped!
What causes dramatic ph fluctuations in hydro conditions so early in the grow, and how can I mitigate it? I have hard water, so I know that’s part of the issue (I tried to install a RO system recently and failed miserably). Other than frequent testing & additives, what can I do?
Hi!
You might need to add some pH buffers to the solution and I'm using potassium silicate (liquid silicon). Basically you need to have either strong acid and alkaline stuff to make the pH "stronger" and it wont change so much
@TheSyndicate, It’s the only sativa dominant hybrid I’ve ever loved. It was my go to in California, but it’s not available in shops where I am now. Fingers crossed that it’s as good as I remember!
