all i use is Jack's Classic 20-20-20 as a soil drench and foliar. i've used it for many years, not only on mj but veges, herbs, landscape and flowering plants. GL

thanks po and everyone else for your inputs

During flowering the leaves should be turning yellow .. but not that yellow it looks like it needs more nitrogen

I couldn't tell You about Fox Farms, But I've been using Bio-Bizz for over 3 yrs now and even their Chart states you use the Grow and Bloom Together ALL the way through Grow(could be different with F.F.) But IF not then You've just been starving them!! Hope you Sort..

And somebody else said it already, But the Breeders will have a much better setup than the Average Home Grow...So the amount of weeks stated won't be the same...Least I don't think so....Can you imagine the Setup some these Breeders have got...

Peace
