Seedlings look weird

[Stoney Roads]

Hello so I am finishing off some old seeds I have they are at least 3 years old. I got a Green Cush and a White Widow from crop king they are growing great nice and fast but the leaves look deformed. Does anyone know or have some ideas why they would look like this. I am using coco with a 400 watt HPS set to 75% at about 30inches the first week I watered with a ph of 6.5 then realized I was wrong with the ph and it should have been a 5.5-5.8 so the past 3 watering corrected it i am hoping that's all the problem was. Any advice is welcome

It can be damage from the seed shell. It could be from what you said ph.
Let them grow, because they will!
Otherwise they look healthy to me
