Hello everyone, I was hoping for some help with my girls
I have 4 White Widow and 2 blueberry in their 3rd week of flowering.
A week ago i noticed the leaves turning yellow with tiny little brown spots on them (mainly on the top of the plants) I am growing in 1/3 compost 1/3 peat moss and 1/3 vermiculite. I water them with filtered tap water. I added a little tomatoe plant food at the start of plowering phase.
Any advice ?

Can you take a pic in blue or natural light so we can see the exact color.

I'm leaning towards potassium deficiency or cal/mag problem.

Give a dose of cal/mag or Epsom salt the next water.

It won't hurt and magnesium helps with uotske of other nutrients and may help absorb more potassium.


My next question, look at the back of the tomato food box for the macro and micro listing. If it doesn't have all the micros listed (copper, zinc, etc) then get some that does.

How many times have you fed it? How much did you feed it and how much run off when you fed.

When using salt based fertilizer you need to water to the point of at least 20% run off to prevent salt buildup.

If you fed only once then feed it good again with some cal/mag.
