Hey guys, i posted on this early on and some said it was normal. All new growth keeps getting the brown spots and start turning yellow. Im growing in rockwool, hanna ph meter and bluelab truncheon. I thought it was nitrogen deficient so I feed it a low dose (150 on 500ppm scale 210on 700ppm scale.) Of super thrive and dynagro. The new growth came green but later spotted and as you can see starts turning yellow. 2 nights ago I mixed some 700-800ppm dynagro, super thrive and I bought that 3 bottle General hydroponics set with micro (5-0-1, bought for the nitrogen) and added the micro. That made it finally shoot up some and sprout the new leaves at top. Now I see yet another brown spot on those leaves, wtf is going on? Tent temperature is solid low of 71 high of 79 everyday. Humidity is low at 17%. Now leaves are also starting to canoe. First grow, full of issues, I could use a hand here please.... Btw it is a greenhouse bean White widow. I read so much shitty things about them now I definitely wont buy again, although I think my problems are still caused by me somehow.
