OK. After looking at your diary. I know you say she has 5 weeks of flower. It's more like 6. She's in the window or very close to been done.
Finish her up. If anything a light calmag diet to help eat up anything left in the soil and let her finish up she ripen that way. Restarting feed again, hmm. You really shouldn't. You can, there's no 1 to stop you. Will it help. Well, the difference won't be as much as you if you just finish her up on a light calmag diet.
Here's a tip, now idk how true it is, but hey, what can it hurt.
So you want to cut sugar leafs in half and fan leafs cut off fingers and bend leafs, tear them stress your plant into thinking its been eaten by pests to help it fight back in the way of producing resin/thc. Again, idk how true it is. But what can it hurt. And prolong the dying time by as much as you can. Try hang dry it whole or whole by nodes even cut from the stem makes it better to hang somewhere nice and cool. I know it's summer and finding a cool place is a bitch but try not dry in 25+c you'll evaporate the shit out of the weed it'll dry way to quick lose terps and all that good stuff.
20c is fine gives you a few degree to play with. Yeah 17 it even 15c would be best. But the cooler the longer it takes to dry so leaving all the growth on it, it socks up all that moisture and sugars and dries proper.
Happy growing.
