If you stop your nutes now at the halfway point in the stage you'll fuc up your grow. The N deficiency that you expect at the end of the stage will come early and you'll get other deficiencies all before your ready to harvest. Smaller buds, less protection from insects and disease, less potent etc. MG is usually 1tbs to a gallon full strength; flush your soil and replenish nutes at 1/4 strength (3/4 tsp) making sure the nutes completely dissolve in the water. Try re-introducing your nutes maybe 2 or 3 days after you treat problem. Check the ph after the flush and treat if necessary because nutes don't absorb properly with bad ph. It might also help to remove and discard the top few centimeters of soil before the flush. Usually nutes are every other to every third watering after that.

Stop nutes and go to plain water two wks before harvest. Nothing extra except molasses if you want a recommendation.

I'd go organic, homemade or otherwise, because it won't burn your plant as easily.

It just so happens that I use that exact same fert for flowering. For veg I use MG Nursery Select and I find it to be very hot. I need to find something better for veg ferts. That said, I've never had a problem with MG Bloom Burst. Every strain I've ever grown can take it at full strength without burning. Of course, just like any other fert, you have to start off by giving your plant small amounts and working your way up. Did you start off by giving it at about 25% strength?

I have a plant that is currently on day 33 of flowering. I just checked my feeding log that I keep, and I noticed that the previous feeding I gave it at 83%. The feeding before that, I gave it at 67%. I'm still working my way up to 100%. If your on day 30 and have already gave stronger doses, then that would explain the problem. If the burn is not bad, then just back off to about 50%. If the burn is bad, then I suggest flushing with 2 gallons of water for every one gallon of pot size and then immediately feeding at 50% strength.

So when should I be at full strength

I'll need a few more details. For instance, how much have you been giving it. Did you start off giving it at 100%? Are you going to flush? How big is the plant(s)?
