SLH looks different

Hello growers. Trying some Super Lemon Haze and I'd like to know if the plants look ok.

In the pics we have 2 SLH and another different strain. I thought the SLH was getting to much nuits so I blocked up the baskets to get them out of the flood and hand fed them. The one went yellow so back in the flood. I don't like the way the leaves were curling under the lenth of the leaf. The second shoot of leaves are skinny while the third set is fat at the base and to a point at the tip. From the pictures on the web I have not seen any like the plants I have, SLH that is.
Any good advice or tips is a good thing.
Keep on growing... CC

Flood system with 3" to 6" baskets, expanded clay pellets, rockwool plug
lights on only feed every 2 hours for 18 min flood,
400w MH 18 hrs on time
EC 1.8 PH 6.0 DNF grow A + B

1.8 ec is a little high for small plants. Haze's dont like alot of nutes

Ok, I have to split up the girls and let the Haze grow in what it needs then, Thank you IVIars for the advice. CC Keep on growin`

Besides the leaves curling a bit and that the plants look very similar to my SLH plants just so you know but there are always going to be slight differences from plant to plant grown from seed. That's why it's a good idea to pick a mother plant and all to get the genetics you want.

You flood your table (how big is it?) 6 times a day for 18 minutes each flood? 108 minutes total a day? I just got a 4x4 table I put in another flowering room next to my organic room so I'm curious myself, that seems alot of submersion for the roots.
