Third auto grow

Hi all! this is my third grow and I'm wondering if my flowers are on track and is there anything I should take note of to be better at growing. I am growing an Auto Amnesia. It has been 55 days since sprout. Feeding with 2-1-6 nutes @5.5pH. Do I need better nutes? if yes any recommendations? Already stopped LST after a few days of flowering.
Pot: 3L
Light: 600W base power (18-6)
Medium: Coco Coir + Perlite + Rice hulls
Temp & Humidity: 29C & 60%RH (it's a bit hot where I am)

it’s hard to say if you need better nutes as we don’t know the ones you’re working with right now, but your plant looks fine so I would not change anything that you’re doing right now

I've been using a generic 2-1-6 plant solution not specifically for cannabis since I started my first grow and they yielded average. I'm guessing it's the temperature that's hindering them from really going (could go up to 31C some days). Unfortunately, I don't have an AC unit and not planning to invest. I just have to be happy with average yields then. Thanks for the reply!
