Hello all I am using fox farm nutes and lately my ph is jumping to high everyday so I bought fox farm sledgehammer to flush my bubbleponic hydro system. The nutes schedule has it scheduled to flush every few weeks but this will be my first time doing it. I am 40 days into veg and 3rd week using nutes I'm trying to maintain a 5.2 - 5.7 ph level but everyday I check it, it jumps to 6.2 and up.

so should I use this sledgehammer stuff or just use distilled water? I only use distilled for my babies and have only a half a gallon of water per plant so the nutes I use are 1 tsp each. My setup is small but I need to fix this ph problem so can someone give me some direction/ instructions.

i am using distilled water, 20/4 light, 3 USB fans, 6 - 6500k cfls, 1 - 6" fan, fox farm trio hydro pack, ph up/down kit to adjust daily. Hydroton clay medium with a rapid rooter starter plug inside the 5" neti pots.

do I pour the sledgehammer with water through the pot to clean out the clay or do I let the mixture bubble in the container? For how long? Someone help please. Thanks!

here's a pic of my babes

Gonna be hard to keep the ph stable in clear containers. Light and nutes dont play well together.

If the pH is constantly going high, like into the 6.7-7.0 range after only a day or two, then you probably have a bad bacterial issue. Even in the 6.2-6.3 range that quickly it usually means something is brewing you don't want around your roots. Clear containers can help spread algae and bad bacteria so at the very least, cover them somehow. Sledgehammer is a tough thing to use properly and can often lead to worse damage if not done right. If you must use it, pour the solution into the container and dip your roots for an hour or two, but I would suggest introducing Hygrozyme to your nutrients. It's a natural enzyme that breaks down dead tissue and bad bacteria. Sledgehammer simply releases nutrients from the roots to correct nute lockout or in the last week before harvest. I'd also start using beneficial bacteria. If you want to stick with Fox Farm, try Microbe Brew.
