Northern Lights # 2

I adjust the pH daily to as close to 6 as I can get it. Based on the answer I got in another post, I believe I have been massively underfeeding my plant. I've been mixing in the nutrients only once / week when I change the water. I was unclear on weather the ppm should be constant or whether it should be mixed once at the beginning of the week and no extra added.

Does look like a calmag or potassium issue tho

What PH are you running

Sounds like I've been massively underfeeding. I change the res once per week and was adding nutrients then and only then. Sometimes once more if I thought it was starving.

Top the res every two days at least. If EC has dropped, top with some premixed feed. If EC has risen, top with pH'd water. I've found this to be the best way to keep it at appropriate levels and it also seems to extend the time between total res changes.

You can change your reservoir water for new nutrient-water every one or two weeks, but in the meantime they need to have the reservoir topped off with pH'd nutrient water at 1/4 strength. Gl with the setup
