Molasses and LED lights

[Quasar]

I have an issue with yellowing of a lot lower fan leaves overnight after adding molasses to my normal nutes 8 weeks into flowering. I'm using coco coir with hydroponic nutes under LED lights and haven't had any problems whatsoever until now. I'm only adding 1/2 tsp of unsulfered blackstrap molasses per gallon to be on the safe side. Has anyone encountered this sudden yellowing or is this just late flower stuff going on?

Yellowing is normal it just means ur getting close to harvest

Also the first time I gave the ladies the sugar they yellowed really good. Had to start them off slow. also what tyler said about the end.

I think the reason they yellow because of any sugar is because sugar turns into carbs and the plant uses that for food so they suck more water/nutes to grow and then drains the nitrogen and then runs out sooner just a thought. It might just be getting close to the end.

Mine did same, I thought it was a deficiency, this post was very helpful.

LED grower and I use 2ml/500ml during the last two weeks- which is when the plants start "fan leaf" yellowing from the bottom of the plant where there is less light.
Generally if the LED is a problem - it starts, closest to the light.- so I don't think it has anything to do with LED's. (or molasses for that matter)- just timing.

Yep I think they look Great!

They are about ready to harvest and are simply burning through stored and available nitrogen. Completely natural and a sign you should keep a close eye on when to cut them. The time is soon. They look amazing. Well done

I have had similar experiences with molasses. Freaked me out the first time but it didnt hurt the plants really. BTW, this happens under cfls and possibly other lights too.
