Out of range Growmie, soil PH range is 6.3-6.8 and coco is 5.8-6.2. What type of medium and nutrients are you using and your feeding routine. Could be PH or low nutrients causing the calcium deficiency, are you monitoring run off PPMs? :love_you_gesture:

Im using fox farm ocean forest.
Im using ilgm nuets.
My first grow went great.
The only thing i did different was packing the soil.

Could i have packed the soil to tight?

Soil needs the ability to drain, the FFOF should have enough perlite for this. Not sure about the statement of packed, you can only put so much soil in a pot :love_you_gesture:
