what is the ph????
Weedhound Reviewed by Weedhound on . If someone can be of some assistance I am in the 6th week and I am at a loss in this grow cycle. At the moment I have a 6 plant eco grower unit with a sylvania 600 watt grow hps bulb I have the homeboxXL and a digital ballast. About 3 days ago I noticed yellowing starting to occur. But before the yellowing had begun the plants were in great health. So far I have done everything in my knowledge to fix the problem. I had talked with various people and they had said overewatering but isn't that impossible with the system I am using? Rating: 5
