I just trying to figure out why you had to say the same thing twice and both had different growing times.
Come on your not really endorsing miracle grow over other available products are you?
Yes I think that does sound like a really bad idea.
6.8 ph is ok but if you can I would try to aim for a little closer to 6.5.
Hes right, you still have a long time I mean 24 days into flowering is still basically the beginning and a lot of strains get a surge of growth during the last couple of weeks.
Here is someone that knows there stuff. Miracle Grow anything is garbage. You can get much better stuff for almost the same price. Shop around.
I would adjust your ph and switch to something made by Foxfarm asap. There products have always kept me very happy at harvest. Trust me you wont be disappointed.
