I went 12/12 today...wondering when is the best time to give mollasses?And when i do feed mollasses is it ok to give it at the same time i feed with bloom and grow or should i give mollasses at one watering and bloom and grow the next?

i use molasses as a bloom boost and feed with biobiz bloom from week 5 12/12 and only molasses the last 3 weeks. 1 tbsp per 1gal water

I've used molasses from about week 5 as a booster too, but there's no way i would stop feeding myself. I just added the mollases along with their usual feed only a small dose though of 1 tablespoon to 5 litres.

By stopping the feed and just using mollases you will quickly get nutrient defiencies. The mollases only contain Mg, Ca, I and Fe if i recall correctly, there is no N,P or K in there

I'm thinking of doing a test plant with it from week 3 this time around to see if there is enough magnesium to hold off any mg defiency, don't know if anyone else has tried this?

Heya skyblue , as the chaps have said in flowers good if you intend using it as some form of booster , personally i use it to feed microbial life so start feeding the bacteria at a 3 or 4 weeks old , so imho opinon it all depends on you're purpose , in flower i would feed the same also grow & bloom etc , good luck .

Nutrients/trace elements found in molasses, include useful amounts of potassium, calcium, magnesium, manganese, molybdenum, zinc, copper, cobalt, iodine, iron and phosphorus, not in the ammounts you would find in a fertiliser, but usable directly by the plants and the microflora. Also of value to the micro flora, is the Thiamin, Niacin, Pantothenic Acid, Vitamin B6 and vitamin E it contains.

Thats alot more stuff in it than i thought, good to know though
