Looks pretty normal. My only advice is stick to your original plan regarding nutes as you might get tempted to start feeding to early or over fed, which as you probably know will cause bigger problems.
Mine is nearly 100% sativa and that's why mine does that but it's not a problem as I'm not getting new pistils it's just taking time for the swell. Now looking at his pics especially pic 2 which I believe is the concerning kola, the kola has a lot more growth to get thru.
Even pic 1 has more...
Its a pleasure, I can't wait to see them babies looking burnt free and ready to grow into big yielding monsters.
I also like the strains your growing interested to see the end product on each strain.
Flush them and feed less in the future. Seedlings need to grow into feeding it's a very common mistake only learnt by making the mistake but I bet you never do it again.
Also 7 oz on your first plant is amazing well done mate but that's going be a hard number to beat so don't beat yourself up if you don't yield that off 1 plant on this grow.
