What's your feeding schedule? Do you ever let the coco dry? Do you feed every day? Do you feed to run off every time? Do you ever use plain water? What is your pH going in and coming out? How old is the plant?

I don’t really have a schedule as such, I just wait until the coco is dry and feel the weight of the pots, I don’t feed until run off every time, yesterday was the first time I’ve just used plain water to feed, the ph going in is around 6.2! I haven’t measured the run off, the plants are a month and a half old from seed

I'm not surprised that you're having problems. Coco is not soil and should not be treated like soil - it's drain to waste hydroponics. Coco should never be allowed to dry out and should always be fed to run off - this eliminates the possibility of salt build up. Never use plain water because it messes up the cation exchange capacity. If you need to flush for any reason - always use 1/4 strength nutes. I would flush your plants with 1/4 strength nutes pH'd at 6.0 - then start a daily feeding program - always to run off. Daily feeding to run off refreshes the nutes, pulls in fresh oxygen to the roots, and prevents salt build up. I feed my plants daily from the day they sprout and twice a day when in flower.

This plant is 6-1/2 weeks old from sprout for your comparison. Fed every day.
