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.then should i rinse my plants with plain water ?
and i want to keep the coco soil moist ?
so i don't rinse the plants ? what do you mean with plain water?
sorry but i'm trying to understand . thanks
