Hi all, im wondering if you all could tell me whats going on here. This problem started last week after i added some Mg to the water before i topped off this DWC pot. Started getting purple splotches which grew worse into these brown spots. This started on the old fan leaves and has worked its way all the way to the sugar leaves. Last week 3 days after symptoms started I drained and refilled with 1/2ml/ gal. of calimagic - 5ml/ gal. of GH micro - 5ml/ gal. of bloom - 1/2 tsp MG - 1ml/ gal 12% H202 and 1tsp of mad farmer MOAB. Symptoms seem to be progressing rapidly. I wasnt too worried, but i dont think she will make it to harvest at this rate. She is in week 4 of flower btw gorilla cookies auto - fastbuds - my rez ppm is sitting at 940 starting off with tap water of 190 PPM Thoughts?
