First time grower, accidental cannabis bonsai please help!

[Jonny_420]

Hello everyone, first time grower here, started two Acapulco gold sativa’s and two northern lights indica. When I bought them I thought they where all photo period plants but turns out the northern lights where auto flower. So they where all started indoors under grow lights and did very well untill just before I was going to transplant, one NL started to flower and the other just stopped growing and I believed re veged? The sativas seem to be doing great otherwise. So question for you guys, what can I do to keep the flowering one healthy, and is there anything I can do for my stunted plant it has barely grown in three weeks since going into large container. I will attach photos of of all my plants for comparison thank you in advance.

Once an auto starts to flower that's it. Just go with the flow.
The other plant feed it nitrogen. Get a good fertilizer and give it a good snort of that and see what it does.
