Need help with plant in 5th week of growth

This is a strawberry kush CBD plant. I don't know if it's me or the genetics but this strain i purchased is giving me all kinds of trouble. This is my most successful one out of five i tried to grow. Let me give the details first...
In happy frog soil in 5th week of growth. 1000w LED Gixxer light at about 28 inches. Started in a solo cup and transplanted last week. While in the cup the plant started yellowing from the bottom up. Looked like nitro deficiency so while in cup I tried a half strength feeding... still no change after a week. I then transplanted to the air pot that is her new home. It had happy frog soil with worm castings, little bit of lime and 25% perlite. I figured the plant might perk up in better soil. The roots looked really good and strong and I watered with some recharge in the transplant to help the roots take hold. But the yellowing is getting worse and more growth is slowing... I properly ph everything and only water once a week of needed, I use a meter to check if it needs watering. Should I continue feeding despite it being in new or with better soil. I did notice slight yellow tips.. I need help cause it's starting to look bad.. pics attached and thank you...

Very small plant for 5 weeks. You're doing something wrong if this is the most successful out of 5 attempts. But one of the first things I would do is check for bugs. That first photo looks suspicious.

I did have these flying gnats in another plant that I eventually threw out. Came in the soil i bought.. happy frog... I have not seen any since... I used Trifecta to treat the bugs... but it wasn't very effective...

Looks like over fed and the bugs didnt help either @ 5 weeks this plant is suffering and will struggle.
Just straight water around the edge of pot until slight run off, dont add anything else.
place some sand on top of soil to get rid of gnats or let the soil dry out before watering to slow them down.
in that frog soil u shouldnt add anything except plain water for the first 3 weeks maybe 4.
You should start some new plants asap because this one will always be disappointing even if it recovers.

What a bummer.... that Strawberry Kush was a real pain in the ass. I am not very experienced but had success with other plants but this one strain, can't seem to dial it in. I appreciate the help and the advice...
