I have this plant that doesn't want to play nice, Dynasty's Cherry Vanilla Skunk. It sucked in ROLS full term and now it is sucking in DTW inside and looking like the same kind of deficiencies in both. It looks like it wants a boost in micros of some kind?

For what it is worth, there are four other strains hooked to the same feed line and they are all doing well.

What do you think?

What burns said....

PH 5.6 seems low and could affect uptake of some nutes.
But I have never used tuper.

Using Jacks in coco, I keep ph between 5.9 and 6.2.

Hope she recovers.

Don't mind raising the pH a little but wasn't thinking it was calcium because of how it hit my outdoor too especially since I added gypsum this year. I'll dose her with some calmag and see how she does.

Edit:. My bluelab meter was dirty. I just went out to adjust the pH and it said it was 14+. I cleaned it off and now it's reading 6.0, 950ppm so it probably wasn't 5.6 last night. This is a tank reservoir

I hear ya. My trusty Bluelab started acting weird a couple days ago. 3yrs old! (Very well maintained)

Gladly trotted down to my local hydro hut and picked up a new one. PH just matters too much in coco not to have backup.

I made a stupid mistake weeks ago (before putting this round in) and I tossed some leftover myco/bennies in my reservoir. Stupid, Stupid. It all grew, stunk, and created slime in my res. I cleaned out everything (res, lines, blumat microtubing, etc) but my Bluelab probes. I'm sure that is what happened to create a film over the sensors. This combo meter is less than 6 months old but the probes LIVE in my res and I never take them out unless I am doing a changeover or refill.

I have plenty of old wand-style pens as backups, I just moved up to this big boy version of a PH meter. This was just a silly user error.

I think your pH is too low.

I am currently running DNA Mills Coco Cork. My first run on it. I was feeding around 5.9 - 6.1 and my plants were doing that shit. I recognized this from when I ran soil too low so for shits and grins I tried different pH on 4 plants that were the worst and the ones that were at 6.3 and 6.5 responded with beautiful growth. I then started watering all my coco plants (29 plants) at 6.3 - 6.5 and they look beautiful now and are growing at a fantastic rate, fucking jacks beanstalk.

So I suggest raising your pH to 6.3 - 6.5 and just see what happens, things can't get much worse. New growth should respond positively.

Good luck and happy growing!
