This is my 3rd run. Everything was going good up until mid week 5. So for the last 2 runs this same issue has been happening. The leaves will start producing these little brown spots and on some leaves the edge of the fan leaves will turn brown and turn to a crisp. I'm not too sure what's happenning. At first I thought it was a calcium deficiency then it started to look like a potassium deficiency.
I tried to flush and reset the feed with 5ml/g of Calmag and a little more npk raw potassium . But it didn't really correct the issue and it seems like it slowed down the bud development. Im getting stuck on this problem that happens around this time, everytime.
Any help would be appreciated! Thanks!
