Growing check

I'm also growing out a Red Hot Cookies and noticed it really slowed down after topping and training (I'm mainlining it). Tbh I think it's just slow with recovery, mine has since been pushing shoots out FAST and has become my tallest plant by flower w2. Imo if you can afford to pick some up, give it some SuperThrive. I started supplementing my plants with it and they've looked way healthier since and respond a little quicker after training. If there was something really wrong with the plant that warranted a restart, you'd see more signs of it physically on the leaves and such. She looks pretty healthy, although judging by her red stems she might be under too much light, or too close to it. Just went and checked mine and her stems are mostly green with some slight red - could just be the pheno though since some of these like to pop reddish flowers from anthocyanin.

I'd dry it out and then give only plain ph balanced water and then wait to see if there is new growth. Probably be quicker to start over, I've had a number of plants in this situation so I finally stopped giving nutes at the early stages. In straight Promix the plants are good with no nutes for 3 to 4 weeks. Then when they get a bit of fertilizer for the first time they take off. Less water, less nutes have given me more consistent success. Good Luck 😁
