Lower fan leaves yellow, new growth is fine

Hi, sorry no pics are included, no internet at home atm, but here's the deal:

About two weeks ago I left the water in my hydro system for far too long, and I'm pretty sure that the old water messed up some leaves on my plants. So once I changed the water, balanced ph/nutes, new growth has been coming in very GREEN but some of the lower fan leaves, some that were the first ones to grow, have turned yellow and are drying up to the point where I just snap them off with my fingers. But the new growth is fine, and there's a crapload of new little leaves coming in, stalk is thick and strong, etc, no curling.

Using 25% strength GH nutes, micro, flora and gro. Any other nutes suggestions?
PH at 6-6.5, humidity at 55-60, temp 75-78ºF, 400HPS light.
Growing some bagseed and a few Ice strains.

So basically, should I worry that some older leaves are dying? I read that once damaged leaves don't recover, so with the new growth coming in being very green and fresh can I just cut off the yellowing leaves so they don't bother me visually?

If the new growth is coming in good you should be ok, but for hydro try and keep your PH between 5.5 minimum and 6.2 max 5.8 being best. Otherwise you will get nute lockout. If the leaves are more than 60% yellow cut off the yellow or trim the leave off.

Good Luck!
