Lemon Tree & Dark Phoenix

Week3 : When I changed the water in the tank I added Micro , Grow and bloom 4ml/l , Sensi Cal-Mag Xtra and B-52 2ml/l but it was too much , because ppm was over 1000 and i think It is too much in 3 week and as a result we got fertilizer burns (only Lemon Tree , because b-52 run out and I did not add it to the second reservoir, then I added distilled water and everything is ok. I think B52 is not needed in vegetation and I will not add it next week.
