The EC and others things that you can see in this week were for all the plants, except for the lemons. The lemons were on 1,7 EC and 5,8 Ph and less distance between the plant and the ligth (i put the tgl 60 closer). During this week i use 1 time potasic soap because i had (i hope that it's a had and not have :( ) thrips (you can see some pictures in my last question) Even if the lemons were close to the flush, the others 4 plants aren't, so i didn't want to risk them. I put 15 ml of Maria Green potasic soap for 1,5 l.
