Lots of changes both positive and negative over the last week. My oldest has some phosphorus deficiency and some other nutrient issues that I'm almost done working through. My second oldest has nitrogen toxicity and is a bit stunted, also working through those issues with a daily 20% run off flush. Youngest just decided to grow 6 inches over 2 and a half days. I switched over to aurora soul bloom and my word does she absolutely love that stuff. Gonna sub it for tiger and big bloom, as i couldn't find any tiger bloom at either hydro shop and needed something quick like. Anywho, thanks for viewing, and check my infirmary thread if you have any advice for me going forward. Strains are, oldest to youngest, auto blueberry, Colorado cookies, and royal cheese. Keeping temps between 78 and 81 lights on with 55-60% humidity. Someone mentioned 55-60 is ideal for my temp range, but I'm going to try and lower it to a solid 50% to prevent bud rot. Lights are at a solid 250w given my youngest is now 4+ inches taller than the other two and keeps getting taller. Might just stick it in a corner in case it keeps exploding. Hoping my nitrogen toxicity friend rebounds and my oldest continues to improve. Thanks for viewing!
