You're lookin good IMO. Don't stress a little coloration on the stems unless it's coupled with other symptoms or poor growth.

Could be this strain or may just want a little bit of phosphorus. Check out rootwise products.

Was die Beiden schon gesagt haben. LED begünstigt violett und solange es nicht mit anderen Symptomen einhergeht, ist es in der Regel einfach Genetik. 😎

Es ist nicht ungewöhnlich das stämme violett werden. Wenn durch HST & LST Stress entsteht, werden die stämme unter LED häufig violett.

My seedling are about to be a week old and I’m concerned about red stems. All of them have it except one seedling. My temps have been up to 87 at its peak right before the lights shut off and around 71 at the lowest before they turn on.

The stems began to turn red
Guys, I need your help! The stems began to turn red. Yesterday it was less, but today it is more saturated and spreads to the veins of the leaves. Could it be a phosphorus deficiency, or am I worrying for nothing? And what is better to do in this case?

Is this normal?
Hey guys and gals, it's my first time growing so I just want to make sure this is a normal looking Seedling. It sprouted about 2 days ago and is smaller than the rest of my seedlings. Maybe genetics? What's your opinion?
