Hi all. I am working on my first grow. I have done a ton of reading and believe I am a little low on nitrogen, but just wanted to see what others thought or if this looks relatively normal. Here are the details: Sensible Seeds Aghan Kush planted in 5-gallon pot with Espoma Organic Mix with Espoma Bio-Tone Starter added 2tbs/gallon of soil (per package instructions). Seed was planted on 4/8/15 and now on day 25 of growth under two 120W CFLs on a 18/6 photoperiod that are always kept 2-4'' from the highest leaf. Growing in a closet with door ajar and gentle breeze from small fan that is not directed at plants, but causes gentle leaf rustling-this is on for a couple hours a day. Temp is 74 degrees F. Yesterday I pruned two small yellow bottom leafs that were a little limp with a bit of yellow on the tips. Today I've noticed a slight yellowing of the tips of two larger bottom leaves. I have not added an fertilizer since this plant was planted and I water when the soil is dry 1-2 inches deep. No bugs are present. I added a tablespoon more of the Espoma Starter with a little water to try to add a little nitrogen. I don't have any Dyna-Gro, but that is my next step. I err on the side of under watering and under fertilizing. Things I don't know: soil pH. Hoping to identify a problem early on if possible, but not sure if this isn't just normal growth. Thanks in advance. Sorry for the annoying rotation of the photos.
if you were erring that soil would be DESERT DRY Humidity? Your plant needs a cuticle so let her dry out
Thanks man. That's helpful, but it does appear to have a strong cuticle. Here is a glamour shot from the same day. As for the soil, that was immediately after I added the aforementioned fertilizer. I agree she could stand to dry out though. No idea what the humidity is in there though. Feels reasonable, but then again that's not really very scientific.
pH of the water, soil, or medium is pretty critical. Add perlite when you repot. Fill my boots with perlite
