Had to go buy some pH up today the plants were around 5 :X I've got them around 6.3, 6.4 right now, but didn't want to keep going in fear of over watering them, so I'll just wait until they dry out then fix them up just right. I also grabbed FF grow big and want to start using it every other watering after I get the pH between 6.7-7.2. I've been reading and most of the recommendations I see is to add however much fert your going to use to water then check the pH of the water and use the pH up/down accordingly. Is this the best way to go about it? Also I was wondering how much I should start feeding them... the back of the bottle says "General Feeding... 2-3 teaspoons/gallon of water every other watering". Should I follow this or reduce the strength more? Any advice is greatly appreciated!
