New Grower First plant, Northern Cheese Haze, Wilting Leaves and Light Yellow Spotting

[Gatz Bee]

Problem: Some leaves are wilting, light yellow spotting on some leaves

Medium/grow method: Coco Coir with about 25% Perlite

Feed: and supplements used: Canna A + B + CalMag, about 5ML of each per gallon of water

water source: Distilled Water

Strain/age: Northern Cheese Haze - around 3 weeks old

light used: HLG 550 LED, usually at 50% capacity, was at around 25% for initial stints. Have attempted 100% capacity and it completely cooks the tent.

Climate: 70-85 degrees Fahrenheit, 20-50% fluctuation. Installing an inline fan later today to help with temp regulation

Additional info: Have not tested runoffs yet, have a PH meter en route. Also considering ponying up for some blu mats as watering is already a pain

 

[Gatz Bee]

Tested PPM of runoff and got a range of 1700 - 1887

Check ur ph even if you have to one at a pet store. I learned the hard way. I check ph religiously

-- Ok, it seems you aren't doing the needed 15-20+% run-off each time you feed, this is why you run-off ppm's are off the charts and you're getting a lock-out, burn may follow soon...
Here's the deal: coco can't be run like true soil, it's a specialized soilless medium... if you try, things will go sideways sooner or later! It has more in common with hydro in fact, and coco is considered a type of hydro medium because of it's physical properties among other things,... there are a lot of do's and don't's, so if you haven't read up on it yet, do so... there's some good info in the Coco section here on all of this... A lot of it related to coco's bitchy CEC properties (cation exchange capacity)
Doing a grow by-hand is a major PITA and labor intensive because you have to test pH and ppm going in, and coming out; this is how you monitor pH, salt build-up levels, and keep the proper flow of nutes (never water alone!), and air exchange in the pot... All that run-off helps flush out old "picked-over" nute solution and replaces it with balaned nutrients again, plus as it drains, it draw fresh O2 in... This is why, done right, coco can be made to produce monsters in smaller volume pots potentially....
Is the Canna nute line the one for coco? If not, you'll need to add Ca-Mg to help maintain the coco's CEC.. This will make more sense when your read up on all this-
