Hi all, I posted this on my intro page then realized I should b posting here.
ive got a half doz plants of the runtz strain. I took cuttings from a friend w out realizing they were diff phenos. All are kind of slow to bulk up so I won’t be running them again. 2 of the cuttings from the same mother are developing purple stalks most noticeable at the top right up to the tip. More than just some stripes. I noticed some purple petioles on some of the other strains in the room but nothing I’m worried about yet. I’m wondering what can cause a lack in P uptake ( if P is element in question)? Feeding steady at 800 ppm. Discontinued cal mag a week and a half ago. Have done two PK boost. Ph coming back 5.5-5.6 , ppm of runoff 860. I’m running co2 gen only 400-800 ppm. Been keeping rh 60%-63%. The room has been running hot. The wheel in my mini split is all gummed up w crap weighing it down so it’s not doing it’s job. Temps over last week 82f - 88f. I’ve since killed the co2 gen and flipped to the air intake fan which is tied to a temp thermostat. Going to clean out mini split today. Oh yeah, nutes currently running, Flora duo part A @ 5 ml/ g and Flora duo part B @ 10 ml/ gal.
I’m switching back to jacks 3-2-1 after this set since I found out jacks 3-2-1 is coco friendly. The pics suck but I think you will get the idea. Ty!!
Oh yeah some light stress w plants right up against the reflective wall in areas gotta b some hot spots is causing some yellow leaves at the tops (is what I’m assuming). Up against the wall is where all the very biggest buds are growing lol!
