I got the feeling gh does not buffer ph in veg, cuz it is ok anyways. Flower easy.

I am having a constant battle to ph my veg solution using gh three part, tapwater, and hardwater micro. In a single day it is back to 6.5 after a nice 5.8. For flower, tho, all I day is top off with 5.8 and it is ok permantly.

So I was reading around and looking at charts and picking my brain trying to figure out why. Then it hit me. The plant only loses P really at the higher ph! So this is why my plants while out of range are looking ok in veg. They are getting what they need!

I added some acid to flower and it stays fine. When and where the P is needed.


Maybe the buffering they brag of works like this. Maybe the extra P ferts bring it down just right, but this calculated.

They are also dead on for needing 2 ml a gallon of ph down to correct ph.

Kinda cool, kind of annoying. I am going to let my ph run in the veg tent for a while. I am sick of using so much ph down every day. Cant be that good.

Just for fun tho i ordered some flora nova to see what is does to veg ph.

GH nutes keeps my normally 9.5ph (no kidding) tap water at a perfect 6.0 - techniflora on the other hand didn't help at all, I could not add enough ph down to fix it.
 
I am using the Lucas Formula with GH micro and bloom (No Grow) with RO Water. PH is holding steady after 3 days at 5.5 - 5.8
