lol I couldn't figure out how to reply. I think you can use it. But start off with a 1/4 of the full mix and don't go over half at the max. If you water every three day I would feed every 3ed watering. My bloom nutes are 0-10-10. the first stuff I had was expert bloom burst 10-52-10 and I fried the first ones. then went to 1/2 mix max and it worked beter. The first number is N and you want that at 0 of you can during flower. Yes that is what the flush is for. You might back off on the nutes 3 week before harvest give or take. feed only water for the first week. Then flush at week 2 and then just water till you harvest. If I'm not saying this so you understand let me know and I'll try to say it different. I tell people I speak bad and type worse.
