pH/EC/Medium issues

the response on the leaves initially with twisting is a similar response to "yucky" but in a slower time frame to how we would do it. the colour fade is possibly the roots being burnt and not being able to take nutes in again yet.. plain water ph to 6.2 for a couple of feeds maybe. they feed from the seed stored until around 3rd set of leaves and then if needed they cannabalize the little rounded 2 that form under the 1st set afer germination. it is like an emergency packed lunch while the tap root looks for water and the side roots start to web just under the surface to help feed later on.
