Ginormous and PH

[Duder]

Hello everyone

I recently ran out of bigbud and decided to try Humboldts Ginormous. I am running a DIY undercurrent using tap water. I had great results using bigbud as my booster and Aqua flakes as my base for weeks 2-8.
I cant get my PH to stabilize using the Ginormous. I followed the instructions on the bottle "5ml for every gallon" and could not get my PH below 6.4 :sign0065:. I decided to dump it and tried 3ml a gallon. The Ph drops after adding PH down but drifts back to 6.3 the next day. Anyone have experience with this stuff?
I am used to adding my nutes and not having to PH at all some weeks, keeping a constant 5.8 until my weekly nute change.
This is very frustrating. I also purchased MOAB since I am running low on overdrive. Can MOAB be using as a booster all the way threw flower? At least until I can get my hands on some more bigbud?

I use Ginormous, but I mix each batch before I water in drain to waste, so I'm no help with your ph issue. What I can say is that MOAB is not to be used thoughout flower, just week 1 (optional) and then the last week or two. A "like" product to the MOAB would be "Big Up" by Humboldt Nutrients, and if you look at the HN's feed schedule it shows you what I'm talking about. Best of luck.

Thanks Papi
I already purchased the MOAB, I did use it in the first week, seems to have jump started things.

Anyone have any experience with this happening with anything nutrient combo? What did you do to resolve it?

Does anyone use this stuff in hydro?

I think im just going to go back to my old trusty bigbid. I cant get much info on Ginormous being used in hydro, although my girls look great im used to them eating 5gal of water a day and I haven't really had to add much water with the ginormous in the rez. Which tells me my girls are not happy with their food. I was thinking of doing the hammerhead/ MOAB combo at the end of flower. If I buy Hammerhead, is there any reason to buy big bud? Isn't Hammerhead basically the same?
Thanks is advance!
