arcticanswered grow question 5 years ago Hi guys. I have problems with plants, I hope to find the answer to the question here. I have 12 plants, 6 of them are 10 days older. I find it difficult to work with the solution due to different growths. I think I give too little fertilizer. I use RO water and the entire line of remo (+ magnifical).x2 600w. temp. 25-26. hum. 40% . tutankhamon fem. remo 1ml / l = 550ppm. I will be happy for any feedback! :)
