Everything is looking good starting week 2!
Getting some odd splotching; maybe PH? I checked the PH with a Vivosun soil tester and normal Vivosun PH stick tester. The soil meter was saying alkaline but the stick was reading acidic. The run off and watering solution both read at 6.0.
I don't like or trust the soil tester. it says that the soil is dry when it is drowning, there's no light, and the soil is always alkaline.
Yo ! Be careful not to put the light too strong and too close at the start, when it germinates it's very fragile and that's probably why the leaf burns. 60 cm is good but maybe too much power.
It's a fairly easy seed to grow, you just need to be careful with light and temperature at the start.
Good luck bro ! & happy growing ! 💪
