Possibly giving too much calimagic but over watering? I thought the appeal of coco is you really can't or it's very hard. I've been watering every day for a while now and first time happening? I did flush and give light feeding 6 ph

Sorry you posted its in coco while I answered. You may be over watering. Water with nutes ph 5.8 to ph 6.0 make sure you get plenty of run off. Then wait for top 1/2 inch of coco to dry before next watering.

Hi mate your ph is off. From the picture it looks like your growing in soil. Soil ph should be in the range of 6.0 to 6.8. Coco/soiless media is 5.5 to 6.5. If its soil your in then increase to about 6.3 6.4

Looks like you are in soil so try upping your ph to around 6.3, manganese is quite a rare def from what I understand - with the calmag make sure you arent adding too much (unless using RO water to up your ppm) as high concentration of Calmag can actually cause a lock out. Check your runoff for ppm and if it is sky high cut back on calmag perhaps?
