From a fellow grower: Im using the grow fert and when measuring my PH its around 7-8 (fox farms soil) I need to get the PH down, will your fertilizer manage this for me or do I need to take additional steps to get the PH lower. Im scheduled to use week 2 of your grow fert this Monday, I believe the Growtime product has a Nitrogen value of 19. My soil is too alkaline (7-8) so I read I can add lemon juice or vinegar to the water to get it more acidic and closer to (5-6). but don’t want to do that if your product will adjust the soil PH automatically for if I double up and don’t need to, I can introduce Nitrogen burn
You need to take additional steps to lower ph. Phosphoric acid is also safe and effective at lowering ph.
Many of us use pH Up and pH down from General Hydroponics to make adjustments for watering and feeding.
I use a pinch of citric acid powder.
I use lemon juice. To lower my PH.
How are you measuring this? With one of those 3 in 1 soil probe meters? If so it’s worthless.
