<span class="link_user">@Smoke_Weed_Maintain</span>, Not really, your plants look like they got really stunted early on and weren't able to vegetate properly going into flower, which is unfortunate given that you're growing an Auto, less chances to fix Veg mistakes.
Those leaves looked like they were very deficient of Cal-Mag and Nitrogen. Try using one of the CalMag Brands around the net, it's not very expensive and you can feed it through the plants entire life cycle.
It's best never to trust a "kit" at it's face value. PH meters are cheap, allows you to check the Water pH coming out of your home tap and use that as a baseline to adjust levels throughout the grow. If you can drain your plants into a bucket while feeding them, it allows you to take better Runoff samples. Runoff PH should typically be .5-.8 lower than your incoming Water Ph
Shoot for ~6.5-6.8 during Veg, ~6.0-6.5 during Flower for feed levels.
You could have also been overwatering, as that causes major stress and stunts root development, there's a fine line where plants are perfectly dehydrated and ready for water and overly dehydrated and starving, usually about a 24 hour window between those two phases.
<span class="link_user">@Smoke_Weed_Maintain</span>, okay, but do you actually measure the PH going into and out of your Soil? Either your light is not lowered enough so your plants are overstretching, or the plants are Nutrient locked, causing leggy stretchiness and less bushiness.
This new TSL 2000 from Mars Hydro made a GIANT difference from previously using their 192w Reflector (Blurple) light. It definitely gave me 30% more in my harvest and bigger fuller denser stickier buds to go with it.
Used the full set of FoxFarm products sub big bloom this time around. the Chelated Nutrients are AMAZING for getting those giant blooms throughout the flower cycle.
100% Need this combination from star to finish if your water does not contain adequate amounts of Cal-Mag. The Tea is great for just feeding the microbes every once in awhile
