Too late to transplant?

Hi everyone, beginner grower here

I have a dilemma, I've been growing a couple of auto flowers for 91 days now, and one of them seems very slow in developing buds compared to the other. Both started growing pistils 41 days ago and I've already harvested one of them a week ago but the other seems to be taking its sweet time, as it's just continuing to growing pistils all over without any end in sight. No buds, no trichomes, just a whole lot of white pistils. Which maybe is a good thing? I mean, the longer it grows, the more bigger the harvest will be I presume...

The plant is 76 cm tall right now.



This is how both of them looked on day 55:



The one on the right stopped growing at this point and went on to develop buds and trichomes. But the one of the left just kept growing.

Now my question is, could this be due to the root system being constrained in the pot? It's a 3.5 liter ceramic pot and I'm thinking if I would transplant it into a bigger container it might help kickstart the bud forming?

I'm just concerned because I heard that ceramic pots make it difficult to get the plant out and it can really shock the roots.

Any advice would be appreciated

Greetings, Mike. I don't think pot size is your problem. 3.5 liters is big enough depending on how you feed her. Your plant looks over watered to me. And very leggy which suggests not enough light. I would not be inclined to transplant at this point but rather would make sure that the plant is drying out to oxygenate the root zone and I would try to figure out how to get more light to help your VPD so she can finish. Best of luck.

Contrary to what you think. Being root bound hastens flowering. Transplanting would encourage more shoot growth but not likely flowering development. The pheno difference is known in some autoflowers. My 2 cents, more phosphorus and restrict light to 12/12 till its seriously flowering.

The advice I have for you is nitrogen toxicity has a hand in the way your plant looks.

Back off of the nitrogen
