Looks great. Welcome to ILGM! 
It’s pretty difficult to overwater in coco compared to soil. What are your watering habits?
Looks like 1st or 2nd week flower with a bit of nutrient burn. (Tips of leaves are burned) Cut the nutrients your giving it in one week period in half or you risk the plant not being able to reach full potential and or stunted growth.
Also are you PH the water to 5.5? That worked well for me when I used coco loco for my soileas medium.
Just let your tap water stand in a bucket for 24 hours before watering. That should remove most of the chlorine. Did you buy a PH pen and PH down formula to adjust your water?
Ph digital on the list. Ty for the water information but i am doing quite the investment as you probably did and will research what water also
Are those in 5 gallon pots or 3 gallon? I use 5 gallon pots and what worked for my plants was watering them every 3 days. To simulate a dry and wet cycle. Your plants will wilt when you under water or over water.
Cheap dollar store fabric baskets. Will order big pro pots. Correct on the water. Ty…
I want only 4 plants in my new tent 48x40x60. Can i use a drip system on a timer or too much of a problem to install?
I usually manually water my plants, while listening to Reggae beats. Remember its best to water in a circle motion around the inner rim of the pots to promote healthy root growth.
