well i just gotta say for one you are in a hydro forum so people are going to criticize the shit out of anybody even mentioning soil and hydro together lol that should just be a given, now you really need to think back on why hydro was even started, to allow mass amounts of oxygen to the root zone of a plant something that is much much harder to achieve with a soil medium. now truth be told the mid and upper parts of the roots actually collect oxygen (this is the way many systems work i mean dirt outside is not always saturated but the deeper you dig the wetter it gets) so if the upper part of the root mass is not gathering oxygen IE stuck in saturated soil constantly, then why even go hydro at all?? although this might not kill the plant your production is going to be half of a actual hydro growers (as you are half assing it anyway) but if you are ok with that then let it ride bud.
ps
im with dude on the fact that you should be watching your ph and ppm/tds very closely as you stated "my nutes have ph buffers in them" well i hate to be the one to tell you but i doubt your soil does so it is going to mess with the ph also the TDS (total dissolved solids) is going to be insane as well because of the shit that is falling in the res. hopefully you dont have root problems.
so best wishes, good luck, and all that good nice stuff i wish you the best and happy smoking.
