This is only happening on the very lower leaves. She's a critical orange punch photo under a 150w light at 50 percent right around day 30. She looks good all around except for the lower leaves. Now. I don't ph my water and haven't fed her any nutrients. Not sure if those could be the cause I'm just looking for help

Newbie here not too worried yet just looking to see if it's something I'm doing weong

Please also confirm whether the red line is a good place to top

Newbie here first grow in stuck between the 2 and when do you think I should do it

My tent specs are 150 watt light in a 3x3 tent temp is 26 during day 22-23 during night critical orange punch photo from germination straight to 5 gallon pot fitmrst grow and yes I'm aware of the stretching

This is my first grow. I'm trying to learn these are critical orange punch on day 2 since emerging from the soil. She's about 4.5 cm

First grow tent I don't understand how fresh air goes in if these are on

Am I supposed to keep these covers on or off? My temps are at 26 inside I just don't understand how air gets in if these are on

Also side question how do I regulate my temps inside the tent? The room it will be in will always be 21 degrees c

Budgets small and I'm looking on amazon for some grow lights and I'd like to keep it under 100 bucks these are the 2 im looking at rn tell me what you think

It's my first time growing cannabis and not too sure what to do in terms of light. I don't have a tent and I also don't want to waste money on too much stuff so early hoping this budget light can get me started

Edit: I've also been recommended the viparspectra p1000 what do you think is the better choice
