Having a little problem here, some orange spots showing up on a few of the plants new leaf growth. My camera won't capture the problem well, I will try to borrow a friends shortly. Also curling upwards of some leaves, again the problem is only on like 2-3 plants out of the 34, should I not worry much? I matched it up with plant problem diagnosis and it looks like a calcium problem. Anyone had similar problems? The orange spots are very few, so I am not freaking out just yet, but I don't want anything to get out of control. I fed them their nutes at 550 PPM yesterday (slowly worked them up) Any advice is appreciated.
