Leaves yellowing overall mid-flower (Soil)

[Down2Clown]

Hey everyone,

I’m currently in the middle of flowering (start of week 5), and two out of my four plants are showing significant yellowing earlier than expected. I flushed them with 6.2 pH water, then waited a few days before reintroducing nutrients at about 1/3 strength. I’m not sure if overfeeding was the initial problem, but that was my first step in troubleshooting.


Details:
• Seeds: Speed Run Autos (Golden Gun)
• Soil: Fox Farms Ocean Forest/Happy Frog mix in 7-gal fabric pots
• Nutrients: Fox Farms Trio, fed at around 75% of the recommended schedule based on previous grows
• Light: Spider Farmer SE 5000

Any advice would be appreciated!

How often do you water them?

They are hungry for some potassium ASAP whatever your feeding them give them more

How often do you water them?

Lately I’ve been watering every 3 days 7Gallons of water divided by 4 containers.

Also, at second glance you have mild light stress too I would turn your lights down 5 to 10%

The FF Grow is 6-4-4, which IMO is too high in Phosphorus and too low in Potassium with the Bloom even worse (and a complete joke). If you switched over to Bloom during flip, when your plants do a ton of growing, you may be starving em. And I don’t care what it says on the bag of HF it’s primarily chipped wood byproduct (and really hangs on to moisture). Luckily you have a LOT of leaves and your plants are sucking up the mobile nutrients.

If you have wood ash it’s a quick & easy Potassium feed. As Groucho suggest a K deficiency will cause the tip and edge yellowing. A cup of ash, 5 cups of water, shake, shake, shake, and then mix a cup of the solution in a gallon of water.
