I’ve been successively grafting lophs on to Pereskiopsis. The oldest 8 were grafted half way through March and the others a month or so in between the smaller assortment. I have been watering and feeding one a week with general hydroponics products to the tune of npk 2-4-3. Everything has been going great until I noticed my oldest grafts leaves starting to yellow. Not really sure what’s up here? These guys are stressed but everything has been fairly consistent about 6 weeks ago I up the light up another 10% but don’t really think that’s the issue cuz none of the younger grafts are showing similar signs, any ideas?

Side note, there are also 2 yellow sticky traps visible
Pereskiopsis are deciduous, they will drop their leaves eventually. They drop faster when dry, so I guess all you can do is keep them wet.
The larger lophs could be taking all of the available nutrients from the plant. It’s response is to drop some leaves
