Yes they are yellowing a bit. I guess Im just nervous to let the peat dry out too much.
If your grow is small enough, and you have time:
(For large and mega-grows, this won't work!)
Line an empty beverage cup with a thin plastic bag,
fill it with your potting mix. twist and seal the opening
of the bag. Use a scale to weigh the cup with soil, and then
use that weight to determine when the plants need water.
Or weigh the plants on a pan balance scale against the
cup of soil.
It's a hassle doing it one-by-one, but plants use water at
different rates, and sometimes their water use increases
or decreases. Bottom watering them all at once means
some will be too dry and others too wet, depending on
the individual plant metabolism.
I've been weighing my cups and square pots for the past
four or five seasons, and have not had issues with soil moisture.
My 18-ounce beverage cups get 4 ounces of water at a time, and
that usually lasts for several days or more, until they no longer tip
the scale against the 'standard' cup. Oh, and I top-water rather
than bottom-water so the whole root ball is moist, not just the
bottom half.
I know it sounds goofy
, but it seems to work for my small grow.
The plants are über-healthy when they get to plant out!
Sorry for the long text block. Good luck getting a handle on
your watering routine. Took me a couple of seasons!
I'll post a pic in my grow log this afternoon...
