I'm 99% sure I had the Golden Ticket Chernobly pheno. Sadly I could not get her clones to take and she did not reveg. :( So good. I only have 6 grams left. But I'm good for half the day if I decide to throw her in my vape.
I did not see this brought up in the thread, my apologies if it has been addressed and I skipped it. Do you have an extract fan as well or only the 380cfm intake? I was using a 120cfm on a 4x2 grow tent extracting the air and it kept that tent at ambient. Canopy temp was four degrees higher...
From the looks of those leaves, it looks like you've got a long flowering plant there. I have absolutely no experience with time released nutes, but I would just try to ride it out at this point, if it were me.
That happens every time I take a seed casing off myself, instead of letting it drop naturally. Only effects growth for the first week. After that identical growth to same strain seedlings. At least that's what my notes and experience say.
