What is the res ph after top off?So, I’m filling the rez with water PH’d at 6.3 but, I just checked what was is in there before topping up and the PH is 8… should I be accounting for that and adding my top off water at a lower ph to try to bring it down some?
The plants look really good right now. Except for needing a little defoliation
I had to do this on my current grow. In fact I had to drain what was in the res and do a full flush to get things back in order. I’m using promix though so that might be a completely different scenario.
I added a half dose of the cal mag. Having already been fighting the deficiency, I don’t want to stop it and go backwards. But, like you said if it’s a PH related issue, this should help it and I can back off it slowly if no more issues show up.
This is a long thread with a lot of good info on many ways to do the same thing.
No. You want the same mix as the rest of the container so that it has the same wicking properties but, as @Olddog Newtrick mentioned, that part gets packed firmly. The rest of the container gets filled with your mix and firmed in like you normally would.
It has crept up this morning to7.3
Tell us again what you use for your soil mix and nutes?
Soil is fox farms ocean forest and nutes are all fox farm as well. I’m using the dirty dozen and feeding at week 4 (last week of veg on the chart) I’m not using the flower kiss and I bumped the grow big up a little to get more nitrogen and hopefully green them up a little.
Yes 6 week veg. Started quad-lining asap to get max. branching. Defol at 6 weeks, wait 3 days (they heal fast) & flip to flower. That was in a 5 gal. SIP in a 4x4 tent. Did the same thing in a 12 gal. tote expecting a bigger yield.... but makes no difference. Same yield. Want bigger plants, you just have to veg longer. I could just imagine how big an 8 week Veg plant would be in a 5 gal. SIP. Probably pull 2 lbs. I've gotten 19 oz. from one plant in a 5 gal. SIP. Only happened once though. Must of been a really good seed.
Like Azi, I quit ph-ing. But if you want to drop the ph use drops of lemon juice. Put a drop or 2 wait 15 min. & check it. If still too high do it again. If it gets too low add a pinch of Baking Soda to bring it back up.
