One of my plants is from bag seed that looks like a sativa. The leaves started showing signs of nutrient burn a month ago. However, a botanist at a local commercial nursery diagnosed nitrogen deficiency and prescribed an iron/nitrogen supplement.
-12 weeks old
-Vessels: fabric pots
-PH is 6.2 or so. Don’t know TDS
Fertilized with FF Grow Big 6-4-4 and Kerex super iron chelate
-PPM/TDS or EC of nutrients: don’t know
-Method used to measure PH and TDS: PH test vial.
-Humidity; Day, Night 30%
I flushed the pot twice in the past two days but the brown spots and leaf curling are getting worse. And the light color of the leaves tells me they’re not getting enough nitrogen I think.
Help! How do I get this girl stable again?
