I know Blackstrap Molasses should NOT be used till last two weeks of Flowering, that shit locks out your "N". Your plant is not burned either IMO, its just has no "N" getting to it. If your plant was getting burned from the soil, the 1st tell tale are the Leaf tips, those would be crisp and and completely dried out. Your plant is not burned bro, its just got a lockout of "N". Flush the plant and feed without Molasses. The only reason I say this is because I did a lot of testing with Blackstrap Molasses. Regardless of the strain it will lockout "N".
I believe me and puffntuff mentioned earlier, you dont need nutes till your plant tells you it needs nutes. Especially in the soil you are using, you can get away with out giving nutes for at least a month with Fox Farms. Study and learn your plants, so you know what to give them when they want something. Almost like a wife or girlfriend...LOL
Oh I am a firm believer you should never clip any fan leaves, they will come off when they are ready. Mother Nature never clipped leaves off her plants so why should we?
