That should be fine. How the leaves look like ?
Leaves mirror the state of health of the plant and tell you what they want or dont want. .

Thats good to know!

Leaves aren't doing too well I think. One of my plants had a really bad problem with leaf miners so I cut a lot of leaves as a prevention measure. Current leaves are light green and a little dry, I think due in the hot weather and all day exposure to sun. I do have a few yellow leaves, but usually they are damaged leaves.

When was the last time you fertilized them ?

If the leave are pale green, then they might need some boost. Any all purpose fertilizer should do. Liquid type will act faster than granular. I would use it at half recommended strength, just to be safe.

I fertilized last week. I do it once a week with a liquid fertilizer @ 1/4th cap per 15L of water.

I posted in another thread about a pumpkin showing a bump rind, and someone mentioned it could be a mosaic virus, so at the moment I am not to hopeful for the health of the plants.
