I would transplant her directly into a 3gal for auto or 5gal for fem. She is entering the vegetative stage and I
would Hold off on femming or topping the important thing is to get her into her new home and let her recover
before doing anything else.
I think it’s time for bigger shoes. Make sure they are big enough to grow into. That works for plants too. The color is telling me they would like more nitro. They look great but a little wet maybe, just need some drainage. Once they hit the third node and multi fingered leaves they are vegging.
With all your fine suggestions, my plan is to move her into a 5 gallon soft pot using FFOF soil. I’ll then give her 4 or 5 days to get acclimated before thinking about nutes. Question: does the FFOF soil provide enough nutes for a few weeks or should I start giving her the FF Big Grow after the 4 or 5 days?
FFOF soil contains enough neuts to sustain her for awhile. I would start with big bloom at 1/2 strength 1 wk after transplant as it encourages root growth. Be careful with big grow as it is higher in nitrogen and it probably isn’t necessary for 2 to 3 wks. I never use above 1/2 strength. Blueberry is a great strain I have an auto coming up on 4 wks,
I would add the Big Bloom and Grow Big after transplanting, personally. The Big Bloom is the root hormone type additive you use with both the Grow Big in veg and Tiger Bloom in flower - hence Big Bloom.
After looking in plant care guides nutrients it looks like it could be the early stage of a nitrogen deficiency which might also lend to the compact growth. Transplanting will probably solve the problem.
