Growth slowed down to very slow

so this plant has slowed growth over past week to practically no growth. Just transplanted into 5 gal from 3 gal 5 days ago. The whole plant has turned from a nice green to now a yellowish green/bright green accompanied by basically zero growth. This color change happened right after I topped it to manage an even canopy. I used some magnesium and calcium and sulfur as a spray thinking that's what it was originally. But no change now a few days after. I am guessing it is nitrogen deficiency and so I watered with 1 tbsp of nitrogen guano yesterday. Guess we will see in next couple days if that was the cure. Since that watering I have seen one shoot grow a half a centimeter or so upwards
I attached some pics. You can see my small garden. In the middle are clones that were started about 3 weeks after the other plants from seed and those clones are taking off right now. Growing great.
Growing organic in peat moss perlite and amended soil.
Any ideas from the pics what is the problem? I've searched and can't figure it out unless I finally did with the nitrogen

Looks a tad hungry..... not much to worry about
I'd up the feed , otherwise it looks fine

pick a nutrient kit, follow directions, they're mostly complete systems, no deficiencies because of the ferts then
dont panic, grow organic

ya thats what I was thinking by now. The new soil its in should feed it well, just thought it wouldve taken to it by now. But it hasn't been a week in the pot yet, and one of the plants has shown growth as of 2 days ago, but it did have the biggest root system of the 4 I transplanted. So guess I just gotta wait and possibly increase my ferts.
