HELP! Leaves droopy and yellow spots

[Blazemeupat420]

Hello all , glad if someone could answer my question.
newbie grower here .
WEEK 3 seedlings
DIY tent with mylar film
im using organic topsoil with
*coco peat , hummus , root powder , rice husk and sand .
ph 6 ~7
LED light 1000lm/ 9kWh
constant temperature at 22 Celsius
18/6 light schedule
wetering 2 times a day

so the problem is my plant is getting droopy with yellowish patches after spraying some neem oil on it right after lights off .( tiny yellow spot on just 1 individual leaf before spraying neem oil) . It has been overwatered before but ive transplant the plant to new mixing of soil and mediums since after . Was wondering if I should add some perlite into the soil for next transplantation which is flowering stage . Pls help , need advices !!

You might have got some nutrient solution on the leaves, which can cause bleach spots (which look worse as the leaves grow). The plant looks fine.

Also, if you start changing the soil composition as you transplant, you'll get uneven drying.
