Yesterday I forgot to water the plants under the LED, so today I watered the same mix. 1/2 tsp cal/mag( actually using GH's Cali-MAgic witch is a 1-0-0 NPK, but also has a little iron in it too) and 2 tablespoon fox farm big bloom. Yesterday I was in a hurry so I didn't have time to PH anything, but today had time. Water PH'd around 6.2. When I mix the nutes it was 6.7-6.8. When I watered the plants I measured the run off and it was 7.2! Is this too high? if so what should I do? Thanks in advance!!!
