First grow part 2 (the march of the yellow leaves)

[Buzkill]

Thanks Daddy,
Ph is a solid 6.5, unsure on EC and no way to tell.

Plants are about three weeks old at this time.

I used dixie cups (will not do that again but it's what I had to work with this time) and the roots were getting crowded.

Any other advice?

Please?
Thanks,
Buz
