Looks to me like they are being underfed possibly..... ?

Up your CF to 1.1 from 0.7 and keep your ph at about 5.6-5.8 and you should be good to go. You have lots of growth so it will need feeding.

Always ph after you have added your nutients.

I always start mine off like this and they are usually fine.... ?
