Hey VP what rate are you using on the zerotol? I just added some to my res at 1:2000 (.064 oz per gal) just as a preventative. Can’t afford duds at the new spot.
I see they actually recommend 1:100 for a soil drench so I’m hoping I’ll be okay. Shit will drop ph fiercely.
I’ve been using it on the plants that have dudded at the 1:100 (1.25 oz/gal)...which I’ve been mixing it in at 40ml/gal. And at 40ml/gal....there is no adjusting the pH! Lmao. That shit stays at like 4.3 and doesn’t move no matter how much pH up I use.
I’m in soil so I imagine it’s not as bad as coco or hydro. I actually haven’t seen any bad effects watering with it. Of course I’m only using it on the duds so far. Some seem to be responding well to it. While others, like my moms, are still dudding out hard. Lookin like I might loose GG4 and FS7. :’( I haven’t given up yet though.
Honestly, I’ve only hit each dud one time with the Zerotol. Kinda scared to hit em 2 and 3 times in a row with the pH that low. But I’m at the point now with some, that I’m about to try it out. Probably gonna mix Zerotol and sm90 in a gal tomorrow and go nuts. With the Zerotol’s pH being so low, and the sm90’s pH being so high...I’m probably gonna create a dirty bomb and blow myself up! Lol. If you guys happen to look towards the east coast tomorrow around 9am EST and see smoke...that’s me blowing up! Hahaha
For the record, I have foilar sprayed some duds with the 1:100 ratio and had no bad effects either.
