Having issues with leaf curling

Can anyone tell me what this could be I’ve been researching for a while and can’t seem to find anything that would really pinpoint what it could be this is my first time growing cheers in advance

Curling/and/or drooping leaves can be a sign of to much nitrogen, overwatering, or both.

Also looks like you may have a calcium deficiency.

What is your PH? Calcium deficiency is often caused by low PH.

Did you chop the fan leaves off ???

I’ve just ordered a ph and ec blue lab pen so I’m honestly not to sure what the ph is it should be arriving in the next couple of days I’ve been watering once every 3 days but I’ve recently started using rain water but prior to that I was using tap water and just some cheap nutrients which is high in nitrogen so I’d say that could be the issue the temp of the tent also gets to 90f in the day time which I’d say won’t be helping and yeah I went through and stripped a lot of the fan leaves
