Could someone help my little lady?

She is flowering, and this has been coming on. The main symptoms are that the mid/top leaves are curling and the lower leaves seem to be having chlorosis I believe.

Strain: Blue Cheese
12/12 from seed
Hempy Buckets
100% Perlite

Could someone help me diagnose the problem? I would greatly appreciate it!

Here are some photos:

Ideas to flip over.
The leaves show a PH problem. At least to me.
And this is causing a nutrient problem.
All a guess.

Thanks for the reply. I have been adjusting to 5.8 before watering, using tap water that has sat out for 2 days. I will try 6.0 and see how she likes it.

this is a hydro system right? Ideal hydro ph is 5.5-5.6
