Can any help me and tell me when to use the molasses and when do I star it and how to use it and mix it any one ???
Some will tell you to add it during veg to feed your micros and some will tell you to feed throughout. You should always use it in an aerated compost tea=ACT. Look up the process of making an act and you will likely find an exact recipe with directions for it's use according to the recipes owner. Just in case you didn't already know an act and molasses are usually used in Soil grows. So if your hydro don't even worry about the molasses your hydro nutes should handle enhancing the trich and terp development.
I dont even reccomend it. It takes months to break down unless you make a tea. Its ok to use if you're mixing your own soil because it will break down while it cooks. If you use it in veg it wont do anything until late flower which is when it needs it anyway. I skip it and just use bud candy or something if that nature around week 6-8 depending on the strain. It has a good rep but honestly i never understood why. I miss the gnats too, they love it.
Tea! I learned the hard way. Depending on the length of your grow, the molasses takes a while to break down. Very little if any might be usable by the end of your grow.
