1stgrow.FASTEDDYaut - o - matic - WW

I have tried to topping one of WW's but I screw it or I don't know. The most important thing is she is alive, growing perfectly and even going to flowering. Eddies are still awesome, but I am afraid of getting too bushy, because tent RH is getting and getting higher. My AC could drying the air, will see. In the picture " Height of the garden" are 2 interesting Eddies for me. Somebody could please tell me that this difference between heights of 5 Fast Eddy plants due to Juaniata La Lagrimosa genetic? I have an EC pen but I don't use it. My carrier is always rainwater, I check the plants every day, I try to focus the signs of unhealthy conditions and as I mentioned before try to minimalize nutrient input. At this point I think this is successful. Nutrient burn comes from prefert soil, maybe this soil was not a good choice. In the end I hope I could flush everything and it's timing will be correct. In this week the nutrient input has been stopped. I used just pure water and the outflow were around 20% for safety. The nutrients which I using are not from organic materials and I don't want to taste it in the final product.
