Dr. Earth does not have a guaranteed analysis and You are not providing enough information about your other inputs. Lime green plants is usually an indication of under-feeding. Even with really good true living soil you need a minimum of 7 gallons to grow one autoflowering plant water only.
Pictures of your plants taken in regular daylight with the grow lights turned off will tell me a better story along with as much of this information that you can provide.
Please fill in this form: (copy and paste part is below, this first one tell what specifically to include)
-Problem: (brief description)
-Medium/grow method: soil; soilless-- coco, or peat based like Promix, etc. (please provide the actual product name); DWC, NFT, etc.
-Feed and supplements used: include brand, dosage/strength, frequency of feeding and watering (alone); method-- by hand, drippers, rercirc' or drain-to-waste,... N-P-K #'s too if you can!
