The rpoblem with having different plants at different stages in the same res is that you can only dial in one ppm level for all of them. I would think rooted clones can handle more than just sprouted seedlings. I agree on 300 for the seedlings if that, but would think more like 600 for rooted clones.

you can keep your rez from 300-400 till the plants are almost 18inches tall, sounds crazy i know but less is more, this way they take up nutes and water at the same rate, too high a PPM and plants will drink more water leave behind more salts eventually de-stabilizing PH and possibly burning and locking out nutes....i have mother plants flourishing @ 400ppm...dont believe me ask Earl, actually the only time i would push the nutes is late flower
