She looks hungry, but no bad deficiencies. Remember however, a visible deficiency means you have been lacking nutrients for up to 6 weeks. Feed that girl a nice bloom fertilizer with plenty of P in the mix. Looks great though, just being picky.
If the leaf stems are purpling on just the stem and not the leaf then it's not a big deal. If it spreads to the leaf then it could be a nutrient deficiency. Sent from my LG-H631 using Grasscity Forum mobile app
Great explanation. It's usually caused by temps and genetics rather than nutrient imbalances. I also own both books and highly recommend the Cannabis Encyclopedia to all growers especially new or inexperienced growers. Best book I have read or bought. Sent from my iPhone using Grasscity Forum
if ya using organic bottle nutes dont use lemon juice or vinigar your benificials could be supressed. also lemon juice or vinigar youll want to leave it and stir so it has time to drop the ph. i use organic bottled and ive not ph my water in 4 years my benifical microherd do all that for me. nutes normally bring ph down anyway molassas can help bring ph down and also give nutes to the plant and help boost the microherd. and purple stems can be a number of things from low phos low mag genetic cold temps watch the leaves low down for N, P, K issues and newer growth for issues like calcium and mag tho mag is kind of mobile in the plant so mag can occur lower down.

It's common in Maine with the low temps. Some strains just get really purple after a frost or 2. Purple isn't always a bad thing Sent from my SM-N920V using Grasscity Forum mobile app
