Just go easy on the nutes. Hit it three times maybe during flowering. And maybe once halfway through with a bit of nitrogen. If the MG hasn't burned your plants yet it probably won't. If they stay lush green all through flowering you probably don't need the nitrogen.
Don't forget to give it just water for the last 2-3 weeks.
