Leaf discolouration

My plant is 3 weeks old from sprouting temp:76 humidity:30 ph is from 6-7 the plant looks extremely healthy and is always attentive to the light. my best guess for the tips browning would be maybe the pot is to big and the soil is staying moist to long but would appreciate any other guesses thanks.

guess again.
If you water too much or too often, then you water too much or too often, aint got shit to do with container size aye?
my guess is your choice of soil and or feeding, watering habits
my second guess would be, well, I'll wait....

Looks like the soil might be a little hot. What kind of soil are you using? Are you adding food?

im using 50% peat moss
50% perlite no bites.
The hygrometer is right above the soil it measures a constant 77 f. Could using lemon as ph down cause any harm?

I watered once 6 days ago and have given 0 nutes. Temp and humidity are fine as well. Soil is 50/50 perlite and peat moss. What's the second guess? It would have helped me a lot more if you removed your ego and had only the intention of helping, thanks.
