I have a plant that is in need of some help. This a trinidad scorpion which is about 6-7 months old and is growing indoors in a soil mix. unfortunately I did not add bone meal into the soil when repotting it so i presumed its calcium deficient. I fertilize with with neptunes seaweed/ fish emulsion every other week and use epsom salts on the off weeks. also i use flora blend with normal waterings. In the last two weeks leaves started yellowing and falling off starting with older leaves.

I run them on a 12/12 light schedule under a 600w HPS. the temperature when lights are on is between 82F-86F and when off is in the low to mid 70's humidity is at 30% and after waterings can reach up to 40%. There are no signs of aphids or whiteflies .

Help Please
