DWC require's that some of the root's be exposed to air...so maybe your water level is too high? hence the over-watered look? Im guessing that your root's are more yellow/brown,they should be closer to white.The yellow /brown would suggest poor root health which will cause many confusing issue's.

im using the general hydro flora series nutes, which i have been told are the best nutes on the market ? 15ml grow, 10ml micro, 5ml bloom..in veg. 15ml bloom, 10ml micro, 5ml grow..in flower.
I have tried stonger and weaker solutions but no change.
I will change to a diferent ph down next time im veging and see what happens.
PH RUNOFF ? does this apply in a DWC system ? Thought that was just for growing in pots ?
yes, the roots are more yellow/brown than white. I use rhizotonic for the first few weeks.
What can i do to improve root health ?
In DWC..how full should the reservoir be ?
What size airstone for 18 litre res ?
Well.. knowing the problem,and knowing the cure are 2 different thing's.I use ebb/flow and drip system's.You should find some of our DWC grower's to get more precise info.

Been reading up on DWC, and once the roots grow down from the net pots, you should keep your water level below the pots (like Dive said). Also the recommended ph for hydro is between 5.2-5.8, with 5.5 being optimal.
ok, quick update.
lights off temperature...18c
lights on temperature....24c
so no probs there i shouldnt imagine. My solution level is always kept about 3 inches below the pots, and the airstone is adequete for my size res.
Therefore..my problem MUST be nute solution related.
Im gonna flush out my system, and replace solution with ph 5.8 full strength grow solution. I am on 12/12 lights now, but like to keep with a GROW solution until about 3 wks in.
Will keep the posts comming.
thought i would post some pics of my last skunk grow. Again, i used the same methods for the last grow, as my curent grow.
The pics speak for themselves.
DAMMIT !!! ive just ben reading a thread on Pythium.
Early stages..Yellowed, droopy and wilting leaves (possibly exhibiting mineral deficiencies). Leaf curl over - ram's horns' - roots are unable to uptake nutrients at that strength because they are infected.
pH becomes more acidic (pH should rise slowly in a healthy system)
My ph DID drop to around 4.6
Reduced water consumption, slow/stunted growth, roots a bit dirty looking..
DAMMIT DAMMIT DAMMIT...its all making sense now.
I said the problems all came on sudenly without me making any environment, system or nutrient changes..same mother plant..which is fine..
Im not the most sterile of growers, who is ? My reservoirs are comming up for 2 years old. After one crop i remember leaving the root ball in the idle nutrient tank for abnout a week, until it smelt that bad I HAD to throw it out..and i dont think i have sterelized the tank..EVER ???
Be clean kiddies...or this could happen to you.
I think it might be time for a Hydrogen Peroxide root dunk !!!
And a sterelizing mission ???
A first class example of the early/intermediate stages of root rot I would say ?
Anyone in agreement ????
I will try to salvage.
Make change's one at a time starting with the most likely,and give each change a week to take effect.
The root's really dont look that bad at this point,If you can nail it down pretty soon you'll be good to go.
