i am a rank amatuer gardener that gets lucky more often than not. i can't offer you any advice other than to say that the molasses thing is working for me. i put 3 ounces in a gallon of water and then give 1/2 gallon per plant. all my stuff is grown out doors in Florida. instead of just putting tehm in sand , i surround the rootball with a mixture of pre packaged potting soil and peat moss in a 50-50 mix. the molasses is working great, my bud growth has shot off like arocket and i plan to use molasses instead of chem ferts every two weeks until first frost down here, which is usually around thanksgiving day. good luck with your crop. there are much better advice givers on this site than i am. i hope all goes well with your crop
