i need advice on what to do here...

so i have one plant that is older than this one in the picture by a week and its so much bigger and healthier. i don't know why this one looks like it stopped growing and is curling a bit. could it be that i stressed it when i transplanted it. i am feeding it exactly like my other plant.

looks like high ph.

Not all plants grow at the same rate, many factors. It looks ok, not yellowing or curling. See what's up in a week.
Off topic, Is that foil on your walls? Have you considered mylar or panda film?

the ph is no higher than 7. yeah that is foil on the wall, i just thought of using it around the area of where the plants are so light is reflected because my walls are not white. by this week i should start mixing it with fox grow big, hopefully it should pick up. i can cut any leaf that looks no good and curly off right ??

Yea you don't Wana use foil
