Bleaching to leaves

I have a Blue Cheese Plant that is otherwise very healthy and growing well. I topped it to the third nude three days ago in preparation for mainlining. Have not had any problems with this plant or changed it’s feeding regimen at all. It is been grown in coco and Is currently in a 2 x 4 tent with five other plants under a advanced LED P150 and advanced LED P300 about 18” off the canopy. It doesn’t look like other nutrient problems I have had in the past and I couldn’t find it referenced in my Rosenthal‘s grow book. Thoughts?

Are those just older leaves from the bottom? If so and the new growth is fine then I wouldn't worry, whatever was going on in the past has already been addressed.

I would hope not. I prep my solutions to 5.5-6.0 and check my reservoirs prior to every feed as it seems to become more alkaline as they sit so I adjust back down as needed. I’ll double-check my runoff to confirm.

If you have a reliable soil pH tester you may wanna use it. Something is off with the pH. I have seen medium have a pH drop over time and that may be the case here.
