Mid week 3

Great set up, I think you answered your own question, 1400 ppm is pretty hot and if you’re feeding with every watering as most do in coco, all those salts start to build up. Flush with plain PH’d water for a few days, don’t worry it won’t have any affect on final yields and your plant will thank you.

Doesn't look to bad to me Tbh. After the stretch it's ok for them not to be dark green. You want them like that actually . They'll crave more p and k now instead of nitrogen . Your ppl does look quite high though . Maybe check your run off PH . To see if it's at an acceptable level and you don't have any nutrient lockouts. In Coco I feed at 5.8 going in and my run off is usually around 6.1 to 6.3.

Hello I suffer with coco growing so It's sometimes hard to give advice... But anytime our leaves get that pale color happening something needs fixing. With you being only the 3rd week of flower maybe running it closer to the 1000 ppm might be a little better. Any chance you've double checked that your ph pen is accurate? I've had a few go out of calibration periodically and it really caused a lot of problems. Now I keep some calibration powder around so i can check it every now and then.
