Hello, here is the images below, I got 3 plants having the Light Green yellowish leaves, and some yellow and dot at the edge of the plant......... I am not sure what cause it? Deficiencies? or maybe just overwatering?
Other trees looks fine, just these 3 have some problems
Room temperature : 27C
Humidity : 70-80%
Growth 2 months.
Watering PH : should be around 5.7-5.8

What are you feeding? Looks like you're in soil. PH for soil is 6.5-7.5. Hydro is 5.5-6.5. Looks a bit like overwatering but hard to say.
