What is this leaf indicating? It was just on the one leaf, now it is showing on two with a third one just starting to show the same. The copper/brown part is crispy. Isolated variable - I had been misting water on them occasionally a couple of days before this happened, that water would have been a ph of 7 with no nutes or anything. DWC - plant is about 6 weeks old, still vegging. 600w mh @ 10" with fan about a foot away Humidity is about 35%, temp is <85, nutes are AN Sensi bloom @ 1,000ppm tds, ph is about 5.5-6, and I use tap water with a TDS of 85ppm
Nah, the roots are fine, a second plant is showing it now I also just switch from Ionic One Part veg to AN Sensi Bloom PH perfect. Maybe it's something to do with that.
