Good Day!
I would set up your carbon filter on the outside of the tent to get more head space.
Babys gonna get big in a larger pot.
Looks like the lights might be too close as well. From the look of the leaves you might have some heat stress and light burn. Whats the make and model number of the lights? Some lights come with recommended height and if it has a dimmer, the recommended dimmer settings.
Looks like she’s in the early stages of flowering.
What other equipment do you have?
If you don’t already have it I’d recommend…
a timer, humidifier, heater, a thermometer and humid meter and an oscillating fan.
Water can be a big thing as well. Tap water can have chlorine and chloramine which plants don’t like.
Adjusting the ph is important as well. Mix your nutrients in first then adjust your ph. A good ph meter comes in handy for this.
Hope this helps
