Hey Girl just wanted to let you know miracle grow is not the right nutes for MJ...I've heard nothing but bad things about it.
Also if it's hot and dry were you live like here were I live just make sure it's getting enough water but not too much...when it wilts it's just thirsty ...It's been about 106 all summer hear ,at one point I had to water 3 times a day.
I put a big bucket of water next to my plants so the heat evaporates the water into the air and is obsorbed by the plant.
Make sure you change the water every 3 days or you'll get bugs.
