Sherb Biker and Watermelon Zkittlez elite clones

Middle of 3rd Week. Sherb Biker is on the right side. Watermelon Zkittlez is on the left side. Both ladys are lookin really fine and doing really good. I started taking off some leafs from the sherb biker everyday to cause some sort of low stress so that it eventually doesnt stretch any further. Havent touched the Waterelon Zkittlez yet but will do a big defoiliation on day 21. update is coming end of the week. update (day 21 of flowering/end of 3. week): I noticed some small brown spots on the sherb biker top fan leafs a few days ago. I believe that a pre exisiting cal-mag deficiency came to breakout because I added a PK booster and therefore changed the dynamics of nutrients availble for uptake. As a quick solution I reduced the ppfd from max 850 to 700 and gave both plants a cal/mag supplement which is biologically based. Also I did the big defoiliation. Didnt really take off as much as I probably could have. Also i could have done more lollipopping. Will try to apply these lessons learned to the next grow. pps: I also noticed some weirdly "burned" looking leafs on the more shaded leafs that where hidden in the last corner and that are pretty far away from the fans i put up for better aircirculation. Im suspecting these leafs are either the old leafs from transistioning into the 25L living soil Pots that got slight nutrient burn at that time, or.... mites -.- not spidermites. but the ones that are practically invisible unless you use 100x zoom on a microscope. gonna grab a microscope today and check the leafs and write what came out in the next diary entry.
