Persian Pie

Smaller container - less food - need to feed more often. IMHO.

In my opinion they all look nice. My guess would be that she has a little less food available than the ones in the larger containers. Even though you gave the same doses. My experience with light stress has been with 🍋 lemon yellow tips, wilt, and 🔥 burn. Some people crank the lights, if they have enough distance. Also, I downloaded ppfd app that helps me greatly. Not sure how accurate but around 850 is sort of a sweet spot for me. Most recommend not to exceed 1000. Very nice grow! Take this advice with a grain of Epsom salt, and good luck. Your harvest is gonna rock 🎸.

i'd guess potassium deficiency... otherwise looks clean but just inc ase check ph and if you know yo don't overfeed can rule out lockout possibilities... usually you see a bunch of issue coinciding with that sort of stuff, though. if it slowly crept in, i wouldn't boost k from previous levels more than 10%, then wait and see... much easier/lower risk to scale up than to scale down.
