As of today, she has been in veg for 7 weeks. Week 1-6 were great with 0 issues, but this week I started to notice some small yellowish brown spots on 2-3 fan leaves. In doing a bit of research I came across a possible calcium deficiency, but I really don’t know... I have since cut these 3 fan leaves off, just in case this is a issue that could spread.

She sits in a 7 gallon pot with “Great Lakes Water Only Soil”, which I water with dechlorinated water, mixed with black strap molasses, and “Neptune’s Harvest Organic Fish and Seaweed Fertilizer”. I will also occasionally use Urb microbes.

My pH usually measures in between 6.0-7.0.

I am using a Spider Farmer SF-2000 LED light from 3pm to 8am daily. With the light on, I am at roughly 76-80 degrees, with roughly 60-65% humidity. With the light off I am at roughly 70-72 degrees, with roughly 60-65% humidity.

Please let me know your thoughts! Thank you!!

How much and how often do you water?

Too much? Too little? Why am I only seeing issues on a few leaves? Why no wilting, drooping, or curling?

Thanks for the help!

To help decipher nutrient issues remember that mobile nutrient deficiencies start at the bottom of older growth and used to support new growth.

Immobile deficiencies are observed at new growth sites.

Have a look at what you are giving to narrow it down.
