the NPK values are on the labels.
If you cant find them try emailing info

BLOOM = https://www.bushplanet.com/media/image/product/2970/lg/dfb5.png
MICRO = https://www.bushplanet.com/media/image/product/2994/lg/dfm5.png
Grow is 2-4-7
Bloom is 0.7-5-5
Micro is 5-0-6
Your want some extra micro and grow in there to make up for some more N if that is your problem.
but I don't think that it is.
You will want to measure your EC and PPM values as this maybe an over feed issues more so then an underfeed issue.
Find your EC going in and your runoff EC coming out. This will help you determine is they are getting to much or not enough.
Do the same for PH.
Best Of Luck!
