I suddenly started noticing these weird white to lime green stripes on my seedlings.
I’m Using
Led cool daylight 6500K .
Soil Plantaflor Potting soil.
perlite.
I’m growing in a huge PC tower ( Grow box ) with two 120mm pc fans input and output.
2 PC grow box.
So 2 plants per 1 PC grow box.
Going to use LST ( low stress training )
All those plants look to be perfectly fine to me.
Just check your pH in your water. Make sure it’s within range.
Just be sure to not overwater them.
And if your potting soil did have fertilizer added to it, it just might be a little bit rich for the babies.
They’ll grow out of it.
I think I see what you are talking about on the plant in the orange container. I’m not sure what it is but it could possibly be the start of some fungus. To me your soil looks quite wet. Do you have a fan blowing gently on the plants and what is the temperature and relative humidity? I had similar discoloration on my plants very early on but was able to stop the progress once I put a fan on them and got the temp up to 75. Would like to hear what others have to say.
