OG kush. 1st time auto

1x 100w and 1x 150w LED
73-82F. Rh 40%
OG Kush by ILGM
Coco in 1gal fabric pot
GH Flora series
LST training

Seed sprouted on Feb 1. Under 80w
Preflowers clusters on march 10. Then moved under the 250w
Feed everyday. Last week was 2.5/.5/2.5. (micro/grow/bloom)
Question. Would you say it looks like week 5 of flower?
Should it be fading color by now? It's as green as ever. (Lights add alot of yellow in pictures)
It seems smaller then other autos on here. Genetics? starting with only 80w? Or to many possibilities to guess?

Thanks in advance for any reply
P.s. the burnt leaves in pic 2 seem to have been an isolated instance. happen on couple leaves around week 3 veg never progressed

Flower Week 5 nute plan: 2.5/0/3.5 +2ml koolbloom (m/g/b) ml/gal.
Sound right?
