The second feeding was about 3 days ago during week 3. It was fed 1/4 strength of Fox Farm Grow Big, Fox Farm Big Bloom, and Yucca powder. Water PH 6.4

They showed sex pretty quickly.
I had them in Solo Cups at first, around Feb 11th, Noticed them showing sex Feb 28th.
Had them all in pots beginning of March.

First in pots.
Beginning of March.

The bigger ones are the double grape. The other ones are strawberry nuggets. The strawberry nuggets are all doing very well now, but all my double grapes are struggling.

One thing I have herd multiple times with autos if you leave them in the solo cups to long they will flower way faster. There tap root hits the bottom and they tell them selves time to flower. I herd a good rule of thumb is as soon as the leaves hit the edge transplant. I got straight to final pot.

Good to know. The roots def hit the bottom of the solo.
I had plants just about ready for harvest in the tent, so I only had room for them in solo cups until I got them out.
I hope that's not what happened.
My strawberry nuggets is doing great, and they were in solos for the same amount of time.

might be a strain depending thing to. Some much grow roots slower take more stress. I would just make sure if your going to do it get them out as soon as the leaves get to the outer rim. Good luck man. you check the tricomes on them? I hate to say it but i think they got stunted im the solo cups.
