Wondering what I'm doing wrong--- my stems are all turning purplish redish and I'm unsure if I'm using the right nutrients and if my lights are the right strength and the right distance right now. It seems to be mostly the top stems that are turning purple, so is this an indicator of the light being too close? Or maybe not enough nutrients? I give 1.5 tbsp of nutrients with a 16.9oz water bottle every other time I water so probably evens out to be every 5 days or so. I've only done this twice so far. I would love any help I can get, as I feel like I'm reading a lot of conflicting information between various sites online and am just so unsure of what to do!!! Thanks in advance! Here's my info: E-Water source - Dasani bottled water E-Source water pH - haven't checked--is there a ph tester I need to buy for this? E-Age of plant - not entirely sure of when I started the seed, but I would dare to guess I planted the seed in August or July, it started budding on it's own mid October so I bought 2 lights and started the 12/12 cycle then. E-Type of fertilizer - Pure blend pro - bloom soil formula (1-4-5) E-Rate of application (if hydro, this is your PPM number, preferably after each component is added)-?idk what this means E-Lighting source and distance from plant - Two 150watt cfl bulbs about 5-8 inches from plant E-Air temperature (both day and night if you are running a dark period) - no clue, do I need a thermometer? E-Air % Relative humidity - no clue again should I be checking this?! E-Lighting schedule - 12 hours on 12 hours off E-Type of ventilation your room has - I'm using a spare bathroom in our home, I open the door twice a day and there is an exhaust fan I turn on for a couple hours every day to try and get some of the smell out!
