    put up some pics for better info. The brown spots could be alot of things, most of the time i notice its a PH problem or an overload of calcium/ magnesium. could also be the plants begging for calcium/ magnesium. THIS IS A COMPLETE GUESS WITHOUT PHOTOS OR INFO ON MEDIUM AND YOUR NUTRIENT LINEUP.

    I use general hydroponics flora series notes growing in happy frog soil. PH around 6.5

    looks like your suffering from a few different deficiencies. Do you measure the ppm's or EC when you mix your nutes? or are you going off the bottle.

    If your Ph is at 6.5 then it looks to me like your plants are just asking for more nutes. Bump up the strength the next time you feed and i bet your plants will show better growth. The damage is done so dont expect them to turn green again, you will just see a lot better growth and the new growth on top will look alot healthier.

    I do nothing to measure nutes i just go off the gh fertilizer schedule. Should i fertilize every watering or just add extra every other like i have been
