28% 75 degrees fahrenheit soil is a lot dryer, stem looks dry, maybe splitting into another stem, or calcifying to strengthen? Noticing there is some spots forming on a leaf. Hope all is okay.

Stem splitting there is normal right?

Had the exact same thing happen overnight—and the same question.

I believe what we’re seeing here is stem peeling, like shedding it’s old skin.
Should be safe and normal!

Day 10/14
28% 74.8 degrees fahrenheit. Got little brown spots on first set of leaves. First introduced to nutrition bottles this week. That may be why leaf is still curled? Hope it’s nothing to severe with brown spotting as well I Hope ph is good… No way to read it myself.

Day 13/14 early vegetation
Worried about yellow spots forming. Tried pushing pod up a little bit but it’s really delicate, worried to much I’ll break the soil… Either it’s a nutrition issue or it’s a molding issue. I don’t own anything for properly calibrating ph sensor. But this sensor is brand new. Should it not be good through one grow? At least day 23? Checked up and down the plant for pest and I’m not finding anything. 28% 76 degrees fahrenheit. Just being honest; money is extremely tight making this investment, kinda wish I knew about all this beforehand but I need to make what I have work. Is there anything I can do without extra investment?

It is a good idea to get the calibration kit for your probes. What kind of water are you using? Use reverse osmosis water or distilled water if you can.
How does bottles # 1-2 look like? If they look like they are being dispensed a lot then you may need to clean and calibrate your probes unless your water’s ph level is causing bottles 1-2 to be used a lot

Looks Good.
Honestly Most Everyone Gets Spots On The Lower Leaves Seems To Be “Normal” In Grobo.

White Widow Late Vegetation day 2/14
27% 76.1 degrees fahrenheit
I was planning on it just hoped I could get through a grow first. Gonna order ph clean kit after new years. 1-2 are not to bad compared to nutrition bottles.
