Good Soil PH & when to use???

can anyone tell me whats a good ph lvl for soil & is it the same for veg as it is bloom?? also when is best to use on plant?? in need of answer ASAFP thanks everone & happy growing

Ph should be at or around 6.5 going in

yeah 6.2 - 6.5

iron becomes less available above 6.5 i have just learned

Seedlings - 6.8

Veg - 6.5

Flowering 6.0-6.2

Ok kool thanks everyone, that's what I have been setting veg & Bloom @ 6.5...


bamacheese- bloom @ 6.2 have yoy tryed personaly??

Yes, and there is a reason scientifically.

Phosphorous, the most important nutrient during bloom, can't be absorbed at pH levels of 6.5 or higher. Maximum absorption for Phosphorous occurs around 6.0, but plants need more than just phosphorous. That's why 6.2-6.3 is the optimal range for flowering. It allows for absorption of N,P,K, and almost all of micros needed. I'm looking for the chart right now to post for you, showing nutrient absorption rates and certain pH levels.

I went out of my way, just for you. And the rest of you guys!! This chart is critical to understanding optimal pH levels. Enjoy!!! +rep for the interest in the raw science behind soil acidity!!!

bamacheese: thanks a lot really appreciate the time.
