My two black mamba clones are having issues with what seems like nute burn on new bud growth as well as older fan leaves followed by brown spots & purpling underneath and on top. Not too worried about purple as it’s suppose to with this strain. Using mix of miracle gro organics, Fox farm ocean, worm castings & part coco coir for soil. Only used two light feedings of Dr. earths organic bloom & last feeding half dose organic cal mag. Run off is 670ppm & ph water & runoff 6.5-6.8. My Pineapple Express is doing great with same feedings as seen in pics. All these symptoms combined with yellowing throughout is really confusing me. They will be 5 weeks since switching to 12/12 cycle tomorrow and all from clone. Any input to help stop burning would be great. Running 400w hps, mars hydro 1000, side cf’s and two fans, one oscillating. Temp around 77 & humidity 47. Temps at night drop to about 67 & humidity rises to 60. Have heat Incase drops too much. Thanks
