nutrients speaking, i am possibly the worst person for advice, as burns seem to occur more than buds...

however, i can offer assistance otherwise...

1) molassas is very sugary, and fully or carbohydrates and all the good stuff plants love. in other words, while the plant enjoys the co2 in the air, it would LOVE some carbon sources (sugars) in the soil so that it can really focus on making big sticky resin glands

2)how many plants do you have? 1000w is a lot of light. it should be aproximately 1.5-2ft above the plant (close as possible without heat burns).
