COCO COIR Yellowing leaves help

[Yettie]

Hello everyone. I just joined this group and am excited to get some good tips on my grows. I am currently growing three gilatos and three night nurses. The gilatos are in the front. I am using coconut coir from bush doctor and gaia green for nutrients. They are under a electric sky 300. The gelato on the far right is showing some discoloration on the leaves. I have found no bugs and am wondering if anyone can help me identify what is going on and how to address this issue. Thank you for any help

Looks like insect damage.

Looks like where you may have dropped water on the leaves?

Interesting toppings in those pots what is it? Are you feeding them?

Its sand. I had some fungus nats in my last grow. I am trying to prevent them from coming back. I thought i might have insect damage but i havent been able to find any and none of the other plants seem to be affected. I am at a loss of whats going on with that one gelato

 

[Yettie]

I read up on that and it said it would effect the growth but this one is growing faster than any of the other ones. Im at a loss

I thought the same thing. I thought it may be thrips but havent been able to find insects and none of the other plants seem to be affected

I forgot to mention. I am feeding them gaia green 4-4-4 and 2-8-4

Ok found this little blood sucker any idea what it is and what is the best way to treat

Fungus knats are attracted to…….fungus! Where does fungus proliferate……..dampness, water. Check your humidity in and around your grow and get it to 50 % and don’t overwater your plants, they will tell you when they need it. You should see a reduction in the knats. You can also make knat traps or use sticky boards. ✌️

I also am a coco grower. How often are you watering/feed your plants? In the picture the coco looks dry. Coco should stay moist all of the time. Do not let coco dry out. It leads to salt build up in the coco. Look up fertigation on the cocoforcannibus web site. Great info for coco growing!
