deficiency leaf

Hi everyone so its been a while to post but recently two of my autos started showing the same type of leaf yellowing can anyone identify the correct deficiency.. thank you in advance… Peace ✌️ And btw they are in the middle of 6th week

4 weeks veg from seed on Friday, soil, using floraflex, temps 75.6 average, rh 73.5%, growing under a single 650w led located 42" away dimmed to 50%. Tap water .01ec, mix cal mag to .3-.4 ec, floralex 2g v1 and v2 per gallon ec ends at 1.6-1.8, i than adjust my ph to 6.5. Fans blowing on the...

Also some weird and abnormal leaf growth, glossy leaves and unusual colors. Anyone got some pointers? Been ph watered with very little alaskan fish fertilizer. Promix soil with bone and blood meal, epsom salt and soil is ph around 6.5 I have not watered in 7 days as pots still have weight
