Might be Manganese (Mn) or Zinc (Zn) deficiency or just a simple Nitrogen (N) deficiency, check the pH in your irrigation and make sure its in optimal range (5.5-6.5) if it's okay then just increase the micro-nutrient and Nitrogen fertilizers you use by 20% and monitor the plants' health closely, if it responds well then increase until plants are in full health and vigor. Hope this helps! Good luck and happy growing :)

Yellow bottom leaves/brown spots on bottom leaves Hi guys, So 4 or 5 bottom leaves of my 7thWeek autoflower looked like this and I ripped them off. Is that ok or did I harm her? Anyway, is that a Calcium def? Should I give her some CalMag? Could it be something else? Besides this, the general condition of the plant is good. Tx!

Yellowing leaves on bottom and middle I am growing in organic soil and transplanted 3.5 weeks ago from .75 gallon pot to 2.5 gallon pot. I noticed some yellowing on some of the leaves, generally towards the bottom but a little in the middle. Is this a cause for concern or do some leaves natural die off?

One of my plants fans are yellowing, spotting, pretty badly. The medium PH is 6.5, same as my other plants, but she just doesn’t seem to be liking it. I’m using nutrients, but not heavily. About a quarter teaspoon per gallon of the flora trio. It’s the mid fans not bottom or new.

Yellow spots on lower fan leaves Hi Growers! First grow here and I am concerned about new yellow spots on my lower fan leaves (one tip is dark too). Soil is Atami Kilomix, heavily fertilized. 2 days ago only one leave was affected. What can it be? Mg deficiency? N deficiency? Too less water (100ml every 3days)?

You are a SATIVA North Shore Maui! You grow tall like the sky! Strong like mountain! You are not descended from short plant!Currently overthinking this plant's development. Pep talk not working. It is a sativa but the shortest plant in my garden. Maybe just needs a trim? The yellow is a concern too. I haven't dealt with a plant this bushy before so not sure if it needs help or not.
