Noticed some slight yellowing and the white blemishes on a couple of the older plant's leaves were getting bigger. I believed the white blemishes were do to a cal-mag deficiency and added that to my feed. Also was using 1/4 nute strength and now bumped up to full to counter the yellowing. Started LST this week too.
@Buddha2, Appreciate it! Ya I should add I used a cob led when they hit flower. I think the different light spectrum between it and my normal leds really impacted its growth during that time. I ended up adding a 2nd 2000w along with those 2 original leds to my 2nd grow and boy are those girls thick!
