having probloms

Thread starter #1
Hi guys , my clones have been vegging for 2 weeks & they r a lot lighter green than when I first put them in.
I have flushed & bumped my nutri up too 900 ppm ,easing them to full strength . is this ok or am I doing something wrong ?
Do they have roots?

Show us some pictures.
