Have my girls got a problem?

Hey guys

These sprouted between the 20th & 23rd April (A: 20th, B: 21st, C: 23rd).

This is my first grow in this cab and this hydro system, do they look ok to you guys? I don't know why but I feel like a newbie grower - I guess my first time in this environment and I ain't grown in a long time is bringing on the paranoia.

They are only 8-11 days old, but I'm a bit worried about the leaf twist on A, which also looks like it might be happening to B, and I'm worried C will get hit also. My first thought was lamps too close, but it really isn't that hot at the tips. 15" should be ample. Then I thought mg def, but there's no discolouration at all?

Not sure if I should be worried or whether I should chill the hell out and leave them to it

Ph: Between 6.5 & 7 from what I can make out with a liquid test (my digital meter has gone missing - new one on the way)
Nutes: Weak Floranova Grow & Floraricious plus (given only once on the 26th)
TDS: 200ppm on base ppm of 37
Lamp: 400w MH (inline exhaust & cool tube) @ 15"
Ambient Temp: 75.9F
RH: 41%


Thanks

i think they look ok. i see leaf twist in my sprouts. they will straighten out. they actually look rather healthy.

I was kinda thinking something would go wrong with the A plant (first pic) because I broke 50% of it's tap transplanting it. So I was kinda ignoring the twist, half expecting it to die anyway, but when I saw it start happening to B, I thought something was going wrong with the whole grow.

Whaddya think of the growth for 10 days? Average? Good?

Tx - maybe I should relax a bit more - but those were my last 3 seeds
