Are these deficencies and what is causing them?

So I have three plants one I of which I think I cause a nutrient lock out and the other two look really good one is starting to get some yellow spots on the leaves and little brown spots as well. I believe it's calmag this is on the bluenana plant, The other plant is very yellow on the new growth I believe I caused this giver her too many nutes for awhile and finally lock out something can't tell if it is iron or magnesium or zinc this is on the frosted apricots and third doesn't seems to have any deficency .

Currently just switched the lights and when I noticed that my frosted apricots plant was turning yellow I flushed and redid my feed. The last 2 weeks of veg I feed them 670 ppm and feeding about once per week with two watering in between. My run off has been 6.0-6.8 in all my plants so ik they aren't lock out due to ph my worry is am I feeding enough now. I just changed the lights 3 days ago and flushed with sledge hammer and tap water then I feed them another mix closer to the first flower feed.

In this feed I used 3ml calmag, 2 tsp big bloom, 1 tsp grow big and a 1/2 tsp of tiger bloom in 1 gal of distilled water my ppm in my solution were 1090 and 6.3 ph. Is that a good feed to give them in the first week of flower ,do I need to up my calmag ?

Using 3 gal cloth pots in fox farm soil they were in veg for 53 days. Room temp and been 70-80 degree and humidity at 55-60%. Using the king led XL 600. If you guys could please tell me what's up and what these deficencies may be I really don't think it's lock out I have flushed multiple times and readjusted my feeds. Ik that affected leaves will always stay yellow but I can't tell in the new growth is better or if it's actually getting worse

Thanks for all the info. What is the PPM of the runoff?

After I flushed each plant the jellylicious was 640 ppm the apricots was 490, and the bluenana was 710ppm so I liked so is I after that feed them a lite flower feed that was 1090 ppm and I check the runoff after in that too just to see and cause I'm having a hard time understanding the ppm so when I tested my run off after I feed them and my bluenana was 1030 and 6.53 ph the apricots was 810 ppm and 6.64 ph and the jellylicious was 1010 6.71 ph I like all those numbers so I left it and imma let the plant eat that and check my runoff once they dry up my ppm should go down correct? If they plant is up taking nutes correctly

I'll also feed them some more molasses and great white on my second watering

@Tech Twiggz Those ranges should be fine. Sounds like you know what you're doing. Hoping for a strong recovery - even though the plants honestly look pretty good to begin with.
