Autos- Citradelic, Trizzlers & Zkittles

Still having Cal/Mag issues with these Autoflowers. I have been adding 1 tea. Per gallon for the last week and they seem to be getting worse. I need to do some research see what else I can try. Citradelic is really stacking up and is super frosty. Still smells like black pepper to me. Zkittles looks pretty good and Trizzlers is really tall in the big tent. She is starting to show signs of a cal/mag deficiency as well so I need to keep an eye on her. The photo periods don’t seem to be having this issue.
