They will stretch, no doubt in my mind about that! Surely the Amnesia a bit more but stretch they will!
They still look a lil burned though, did you cut back on nutes or plain water still? Amnesia is the sensitive type of girl, I have her angry over nutes almost every time I run her..
The Amnesia is still on water, TMC is on low dose nutes with all new growth fine for now

cause in my space I had popped two FruitCake auto beans but only one sprouted so in the pot with the no-show I buried a new seed, a Candy Dawg auto.. This was two weeks ago and today guess what, miss Fruitcake Noshow decided it was time to surface lol, so now I have a 12 days old Candy Dawg and 1 day old Fruitcake that took 11 days to germinate..and they're in the same pot, haha.. I still wonder though,how she made it all they way over to the rim of that rootpouch! Amazing plant, never a dull moment with miss Cannabis!
