Can't figure out the issue

[Friedrice0101]

Hi All,

I have been having issues with this for some time now throughout multiple grows. I dont believe it is bugs or nute burns. Starts to occur about week 4 of flowering. Could really use some help and feedback.

Coco (Tupur Gold)
6.0-6.2 pH for flowering
Advanced Nutrients
-sensi coco bloom a&b
-b52, big bud, bud candy, overdrive

Temp ranges from 75-90
Humidity kept between 45-60
Intake and exhaust fans
Airflow exists
CO2 was used during first 6 weeks of flowering ranging from 1100-1500ppm
Gavita LED about 20 inches from top of canopy
Pesticide used is plant therapy by lost coast
About 10% runoff when watering
2 gal pots
1000-1300 ppm

1000-1300ppm is the feeding nutrient

Yeah way over fed. Likely not feeding often enough and letting it dry to much.

That's a lockout.

Back the light off to 30 inches and Likely need a large flush. I'll have to look in a bit here but I think you nutrient ratios are probably and issue too.

Ph and ppmof the runoff not the infeed?

Driving right away here but have a read here.

HOW TO WATER COCO FOR BEST RESULTS.

Ok writing this cause i see this issue often and rather have a thread to link than explain this each time. This is not my work but a collection of info from many members here and I have put into practice myself. So first off COCO is NOT soil. For best results we want to keep it saturated...
