This is my second attempt at this by myself ,my roommate was very proficient in growing and I picked up few things off him. I lost my last crop to warm temps in dwc res causing the dreaded root rot. This time around I am doing 4 Think Different at 2 weeks and germing 3 Sweet Seeds Red Poison at the moment. My setup is 600 w HPS/MH with digital dim ballast, 4 Think Differents in hempy buckets soon to add 3 Red poisons in a 4by4 air conditioned room. I'm using AN micro, bloom in lucas formula also HandG roots excel,cal mag, botanicare silica blast and blast off and floralicious plus (just as foliar till they get little older) Anyways I have a couple of newbie questions. First I have noticed in the last couple days it seems the outer layer or "bark" of my stems are splitting and peeling away. Is this normal for 2 week old seedling, I'm guessing its just stem growing but after last bout with root rot I'm trying to avoid any signs of root or stem rot. My second question is as a newbie I of course was a little overzealous and started full strength lucas formula a little soon and got some nute burn and bottom 2 sets of leaves. I flushed my hempy cup thoroughly with phd water and a little botanicare clearex and seemed to help and top sets and new growth seem fine but now I am getting occasional random leaf droop, its not severe and maybe I'm being a little paranoid but just wanted make sure if that is a side effect after a little burn or could I have another problem. Again I am a little "green" at this so take it easy on me , just trying to be thorough and tap into the vast knowledge out here on the AFN! Thanks !
