First time growing - Need some advice - 4 Weeks Since Seed Popped
QUESTIONS AS YOU READ:
What is the issue with this Northern Light
** What are your recommendations to fix the problem?
SETUP:
2x4 Tent
Duct Fan with Thermostat/Filter
2 Small Fans Running
2 Spider Farmer 1000’s
AGE: 4 Weeks Days since popped.
CONDITIONS:
LIGHTS: 18 inches above plants, set to 70% Dimmed
WATERING SCHEDULE: Sun/Thurs - Nutes, Tues/Sat Water (to run off)
WATER PH: 5.75-6.0
SOIL: Fox Farms Bush Doctor Coco Noir
NUTES: Fox Farms Soil Trio - at 1/2 Strength
TEMP: Steady 73
HUMIDITY: Steady 60
PLANTS & SYMPTOMS: (All Auto Fem Seeds)
Northern Lights - Auto - Feminized
Overall: Early stages of sickness
Stems: Green/Healthy
Leaves: First set look horrible - Browned/Crunchy
Problems with New Leaves: The dark green healthy leaves are starting to get lime green around the veins. Dark green is now blotchy spots slowly moving to brown. Leaf tips are slightly curled up. It appears the symptoms are slowly moving up the plant to the new growth…
Timeline: I started to notice very small changes to light green color 3-5 days ago. It looks like it is getting worse day by day. ** Over the past 24 hours, newer leaves have canoed and the plant is losing it’s dark green pgiment.
MY PRESSING QUESTION:
What is wrong with my Northern Light?
HOW DO I FIX IT?
Please help:
Diagnose the issue.
Provide your thoughts on getting it back to dark green and healthy.
NOTE: I am growing 4 other plants on the same water/PH/light schedule and that are all healthy.
Sunday/Thursday - 5.75-6.0 PH water with 1/2 strength Fox Farms Trio Nutes
Tuesday/Saturday - 5.75-6.0 PH water
Watering to run-off each time.
Run-off is 6.1 PH and 2123 PPM
(Water before adding Nutes is around 150PPM)
Just realized, I’m not draining my run off after each feed, so that is a collective run-off of 4-5 feedings. I will drain and test when I feed tomorrow.
The problem is not feeding with every watering, not watering at least once a day, and not feeding at full strength. Cal-mag should be added with every feeding to keep the coco from binding with essential nutrients.
Coco is NOT soil and needs to be treated differently.
If you want to learn about growing in coco you should spend a few hours learning about it by visiting cocoforcannabis.com
If you have coco loco it’s to be treated like soil it’s confusing. That’s the way coco loco works though. @PharmerBob has good advice and the 20% runoff still stands when feeding nutrients but the PH should be 6.2-6.8 in fox farms coco loco.
The only true way to find the PH in a soil medium is to do a slurry sample. So get some distilled water and learn to do that.
I’ve learned the hard way with coco ya gotta add cal mag. And do not let the pots 're absorb the runoff. Always feed til runoff and dont have to worry about stats of what comes out just keep putting in at correct levels.
