| Re: What deficiency is this? (PICS) Glad to hear that you're not using all 3 ferts at the same time, so you're right, that is out as a possible problem. To PH test your Fert solution, yes, you want to test the combination of water and ferts. I assume you probably have a gallon jug of water or something like that, and you have been adding ferts to it. Hopefully you have some sort of a PH test meter or even better, a liquid PH test kit. All of the test results should provide a clearer picture of what is going on. |
