Tbh no my friend phed my tap water and it’s around 6.3 do you think it could be ph issues ?

PH issues can manifest in a bunch of different ways. What kind of soil are you using? If it's not a nute rich soil, you may need to give it some nutes, 1/4 strength to start.

Plagron light mix soil and iv been feeding the 2m per L of ionic veg feed, I only started the nutrients a couple days ago do you think it could be because of this ? Thankyou

Could be. Keep an eye on your nutrient PH, don't overfeed. Everything else looks good. I wouldn't be too worried.

Il buy a pen right away sure I seen one on Amazon for around 10 would that work ok ? Also the big one is an auto iv been taking it out for 12 hours per day as the rest are photos and have been under 24hours! How long should I be leaving it under the light to get the best results ?

That doesn't look concerning. Usually after a transplant they will decide to drop some lower leaves too from shock. I like to use that as an opportunity to defoiliate.
