    make sure intake ph is between 6.3-6.8 and measure the drainage after, if it's significantly lower or higher you got a lockout going on.

    if your PH is good bump up the Nitrogen in your regiment

    if the leaves go yellow from the mid section or bottom first your plant isn;t getting enough nitrogen, and either one of those could be the cause, but you HAVE to make sure PH is dialed in first or you will compound the issue should that be the problem and you try to just raise the nitrogen levels.

    Yours just looks like simple N deficiency, but always worth checking ph any time you can, i religiously PH my flush water and nutrient solution. intake and drainage.
