Mine have been up for a few days , and I've noticed the leaves are kinda
yellow . These are planted in potting/starter mix , new stuff . They spend
most of the day outside when it's sunny and above 50° . I water when the
soil getss dry about 1/8" deep , and the <paper?> trays they're in have good
drainage , so they're not in standing water .
The pumpkins planted the same day are fine , as are the marigolds . I'm
just wondering if this soil lacks something tomatoes need . It does have
slow-release fertilizer in the mix .
These trays are inside the house except when they are out on the front
porch in the sun ... soil temp should be well above 60° . I'm just wondering
why the leaves are so yellow - these are the first pair of leaves . Other
than the color they seem to be doing quite well .
Just curious, first true leaves? If your plants are at the stage of
needing more nutrients you might try looking into your "slow-release
fertilizer in the mix" at this stage. Doesn't sound like a low
threshold photosynthesis issue.
Do you know how/or when the nutrients in your mix release? There are
as many “slow release”; “controlled release”, or some such “coated”,
usually formulae as there are companies making them. They release
their nutrient(s) in different ways, some at different temps and not
all contain micro-nutrients. There is no one-size-fits-all
If you do not know about using controlled-release (CRF) and slow-
release (SRF) fertilizers you could start with this article and maybe
a few of the side bars from it, perhaps research the specific brand
used in your mix:
You're over my head ... these are the very first pair of leaves outta the
seed , and they're looking better now . First true leaves are just now
beginning to form .
Thanks for the link ! The stuff I used this year is a "potting/starter mix"
that's supposed to be good for about 3 months , I have no idea what it
actually contains or how/when the nutrients are released .
you young !
