Been going TOO good? What to do?

Okay so i have an auto and a cheese fem growing, from seed. Haven't Grown before.
auto is on day 26 and fem @about 20.
auto WAS growing really short and bushy, which is perfect as I am growing in a 26" high server case.

This is it about a week ago...


Feed it some Grotek monsterbloom about 4 days ago, didnt really do much for the first 24hrs. But now..BOOM. Side branching has gone megaNova.


She hasnt grown anything that looks like a bud yet. and im starting to get worried if it keeps growing at the rate its going to be HUGE.



Stems are so thick... Ive never seen anything this height With such chunky bases, almost looks freakish lol. Not that ive seen anything like this before.



heres a few canopy shots just cos their so pretty.



There at about 12". I have about 10" of room left.

I thought the 26" case, with a short auto flower would be okay.

Do u think Im going to have to re-home my girls?
Are they going to get much better?

Only ask cos i need to think about an alternative early cos i work alot.

Many Thanks.

What are you lights set to? My understanding is one is auto one reg. You will need to change lights to 12/12 for the reg to show sex. Which is not ideal for the auto but its the hand you are dealt when you run those two together.
