Can anyone shine some light onto why my leaves are turning color?

Need some tips from fellow growers. Why is my leaves are looking like this, everything seems to be rocking along besides the discoloration.

start of a magnesium deficiency.
I see your using some cal/mag all ready
water temps 68-74-F your in hydro?
I thought it looked like soil...

Thanks for the input. I was thinking it was mag def.

Yes I use 100% bio bizz coco in a flood and drain system.

I added epsom salt to the rez 3 days ago. I just changed the rez, but w/o added epsom.

Should I add more epsom back in? It doubles my ec when I do. Is that a problem?

It might be your nutrient solution temperature is a little on the high side. 68-F optimal
As your PH rises your plant should be taking up more magnesium.
If your PH is to low your plant won't be able to take up any magnesium
IMO- I'd try and run at 68-F nutrient solution. at 5.8 PH letting your nutrient solution rebound back up. you can rebound up to 6.5 before you adjust to change your nutrient solution PH.
You Drain to Waste?
Some plants can be a little weird, as to what PH range they like to be in. They say PH 5.8 for most plants will get you in the ball park which is true, but some plants need a special tweaking.
I had some plants in DWC that loved to go from PH 5.2 to 6.2.

im not positive but to me ( & and i might have smoked a little too much tonight) the first one looks almost like early stages of a K def or a Mn def as topfuel said

Thanks for the tips. I will give it a go.

BTW, I do recirculating.
