Are these plants healthy...?

just my 2 cents, what strain? the thin leaves look very sativa. pure sativas can be very light feeders and sensitive and hard to grow indoors.

Lightest feeders I’ve had were very indica dominant Blue Widows. Heaviest feeders were Sativa heavy jack 47

oops. I only grew 1 pure sativa not dominant but pure 100% sativa and it is super light feeder that even the breeder says seriously, don't feed a lot. As a result I noticed when I read about pure sativas because I'm interested in them several comments regarding that they are usually light feeders but never read explicit mention of a heavy feeder. Also that pure sativas are hard to grow indoors under artificial. I imagine though the giant outdoor sativa trees you see pictures of can consume some feed. I thought his leaves looked close to pure sativa so that's why I brought it up.

Narrow leaf ... Sativa.

As far as your ph .... drop to 5.8 ( to allow for drift ) ...

Purple stems ( May be from lock out of elements more plentiful at lower ph ) .
