You should always have nutrients in your water, with coco. So keep them moist, but never with water from the tap. Your ec reading is high, and it looks like there may also be heat stress. Lower the strength of nutrients a little bit, make sure you feed the plants every day. Do not rinse with tap water, and try turning the light down a little bit.
Thanks
There's obviously a language barrier here.
what do you think about this?
Dude........I've already told you that your EC was too high and to feed every day.......not every two days. I don't know how much plainer I can make it.
just from looking at them, you are giving them too much nitrogen, there clawing (look it up in search engine) and search for the correct EC for plants in there too. you will find loads of great info, then you can ask spacific questions and get better answers. you don't seem to be listening to what were saying man, don't panic, they can be saved if you listen to whats being said.
