Interesting, I'll give those a go in the future. Am currently using the Advanced Nutrients line. Grow/Micro/Bloom, and the supplements at different phases (Piranha, B-52, Bud Candy, Overdrive). Seems to have worked well to date, but something really hit the fan in the past week.
Yeah I thought so too, but I've been giving 2ml/L of Sensi-Cal CalMag with every feeding. Could it be natural senescence? Plant is probably 1 week away from having the right amount of amber for harvest...
Ok thanks. The yellowing veins seemed like lockout issues to me, which makes sense if you consider the pH of 5.0 (near everything is locked out at that level). So I was wondering if I should FloraKleen it to a more nominal range; am assuming that salt build-up is throwing pH and EC. I always...
Grow is in coco coir, using the AN line of nutrients. Feed water was always measured at 1.0-1.1 EC, pH set to 5.7-5.8. Runoff has typically been good, but it seems to have taken a very fast turn for the worse. I've checked my instruments, and they are well calibrated.
Is this typical close to...
Just wanted to post an update. I've built myself a system with an SHT30 sensor to monitor VPD in the grow cab. So far, I've been able to keep it in check. The system sends me text messages if it is trending wrong or exceeding bounds, so that ought to help me eliminate a variable and quickly...
I wonder if the site's Calmag PPM is balanced by the higher pH? Higher pH means less nutrient uptake right? Forgive me if I'm wrong, very new to all this -- trying to soak it in, and the information varies greatly from site to site.
The nutrient schedule I've been observing has been this one here:

Thanks for helping!
1. Coco coir is buffered, was made with these instructions/video:

2. I am feeding CalMag with every feeding, I've been following these instructions here...
Seeing new symptoms on a first grow. Coco, pH 6.2. Temps 23-25, 65-70% humidity (trying to keep to VPD chart)
EC is at .8-.9
not sure how to fix:
appreciate the help!
So I had one night with better VPD, temps were 26-27, and it was sitting around 72 degrees F.
Unfortunately, it looks as though this "tip" problem is starting on the leaves at the second node as well.
What ailment does this? Starts on the lower leaves, works its way up, and crisps up the leaf...
