First-Ever Indoor Autoflower Grow

As of the night of May 8th, the plants are getting bigger and the growth seems to be faster every day now. The Seedsman White Widow Auto and the Dinafem Critical Jack Auto have even started to develop a slight skunky/danky smell already! I watered & fed all of the plants tonight because they were thirsty. As of the afternoon of May 11th, the plants continue a crazy amount of growth each day. I've never done a grow indoors or with autoflowers before for that matter, so it's cool to see these plants take off so quickly. I took some measurements just to see how tall they are: Mephisto Ripley's OG is 5" tall, Dinafem Critical Jack Auto is 6.5" tall, Dinafem Industrial Plant Autoflowering CBD is 6" tall, and Seedsman White Widow Auto is 5.5" tall. All plants are between 22-24" from the lights. I noticed these last couple days that the Seedsman White Widow Auto has some yellow/orange spots on some of the fan leaves; my guess is probably some minor nutrient burn. Temperature and Humidity ratings have increased slightly but are staying more consistent now. I might start on some LST before the end of Week 3... As of the afternoon of May 12th, all 4 plants have been watered and fed again. I played around with some bending and leaf tucking last night and this morning. I already managed to snap a lower branch each on the Ripley's OG and White Widow plants, so apparently I need to be more careful. The Seedsman White Widow Auto has some gold coloring on the edges of its fan leaves, perhaps it is less tolerant to the feed?
