Your PH should be between 6.1-6.8 why are you using PH down. Are you sure that plant is 2 month's, I got 3 week old plants way bigger than that. You also need way more perlite in there.

Looks like a ph problem. Coco is a soilless medium so you want the ph between 5.8-6.2. And it looks like very little perlite is in there, I'd add more if possible.

If you want more help, just fill out this form and we can deduce everything:
How many plants? What strains?
How old are they?
Indoor or outdoor?
How big is your area if its indoors and is it well ventilated?
What medium/soil are you using?
Whats the size of the containers?
What's your lighting set up?
What's the temperature and humidity like at any given time?
What's your ph like, both medium and nutes?
Any pests around?
What is your watering schedule like?
