PLEASE HELP ASAP

So this is my first grow and everything is going pretty good other then the fact about 3-4 out of my 10 plants are yellow and have been for like 3 weeks. Just started week 2 of flower . Absolutely can not figure it out why they’re yellow. I use the basic flora series and I follow all the measurements. My buddy told me to give the yellow ones cal mag so I did and nothing really changed . HELP
 
I started from seed and kept the ph at 6.5 , they started yellowing so I brought it down to 6.1-6.2 , no change , tried calmag no change
 
They’re all the same strain , GSC from ILGM.com but I’m guessing they’re different phenos considering I feed them all the exact same thing and some plants are reacting differently then others

From the limited information here.. Im gonna say you're ph locked out. What you put in does not "buffer" at that number. You may put in 6.5, and the feed may buffer the soil at 5.4 Runoff/slurry tests are unreliable. Get a good PH direct soil probe. Ask me how I know.

I'd do some searching about ILGM seeds. Here's a quote from someone who grew their seeds.
"Lol i stand by my post and i wasn't ripped off financially. Just got stuck growing bad genetics. 7 plants all completely different, different flowering times, nute requirements, and vastly different quantity and quality of buds. No stability, oh and 2 of them were autos. They were all supposed to be photo period".

OK, since you asked for it. How the hell would you know?
BECAUSE I ALMOST LOST AN ENTIRE ROOM! I though I was short on this or that... so I started throwing more crap at it making it worse. Renfro talked me into buying the Apera. Root zone was at 5.1 .... locked out. Fed in at a hard 11.5 PH mix at 3:1 flush, and it settled back at 6.8 at the root zone, and they all finished fine.... I really thought I was gong to lose 90 plants.
