Possible Ph or Nute Lockout??

Good afternoon everyone. I am new to gardening of the medicinal kind, but not new to gardening entirely. I have done hours of research on what the problem could be and I think its magnesium or maybe iron. Their are three plants total and all three are showing the same lightening of green, and green veins which made me think magnesium. The plants are chemdawg #4 and they are in day 25 of flowering out of the 65 that I am going to give them. I have topped all plants, and trained them well and all the plants look very good I think, just the leaves are slowly getting worse. I know they do this towards the end of flowering, but isn't this to soon? I have all three in 7 gallon air pots, and water, feed, water, feed with flora nova bloom at half strength so 5 ml for the two gallon water pail plus half strenght cal mag from GH and then that's for each plant every 5 days or so. They are under a California light works 220 full spectrum with 5 watt LED chips. The light is exactly 15" above the canopy and a clip on fan is blowing over the top. The temperature is 76-80 during the day and 70-72 at night with a humidity of 55% in my gorilla grow tent, and I also have a oscillating fan and filter. I sprayed with Epsom salt last night, and cant tell if it made a difference. I do have cal mag, and can try foliating with that, but will wait for suggestions. I tested the water run off three days ago and it was 5.8-6.2 for all the plants. Should I run Ph of 6.5 water with no nutes through it maybe 6-8 gallons to flush the soil then reaply at half strength? Thanks for any advice I really appreciate it.

Ok I will Ph 2-3 gallons of water to 6.8 and add a full strength dose of cal mag to each one and well thoroughly water them tomorrow when my lights come on. Does this sound good? Yield shouldn't be effected to much by this to muc ya?

That sounds like a plan. Yield shouldn't be affected once the deficiency is taken care of. It's fairly common to run into this sort of thing. They look good though, boss. Best of luck. Welcome to RIU. Keep reading.

Ran 3.5 gallons of Ph 6.8 through all 7 gallon pots with full strength cal-mag added. Lowest Ph after all said and done was 5.7 and highest was 6.3. Flowers are starting to get sticky, but not much smell (not a bad thing). Will keep you updated if all works out. Now just to let them dry out for 5-7 days and re apply nutes. Thanks
