Cloudy grow

Hello there! To give some background knowledge, I've grown bag seeds and what not a few times throughout the years that ended up being males. I finally took the plunge, went fully in and splurged on all the equipment to have a decent quality medical grow. I have an idea for what I want to do, as I've done LST, Defoliation, and Topping in the past. But since I'm mostly working with Autoflowers, I'm hesitant to top it. If I do, it would be after the second or third node. I'm not sure if the Skywalker Kush I got is an autoflower or not. I had gotten it as a freebie pack from Seed Supreme from Mephisto, and all the background info I find on this strain from them is that they had an autoflower that was out of stock (apparently not!). ANYWAY! Off of the long amount of back info; I germinated these seeds on May 18th, then planted them on May 20th. They were slow to grow. I got super excited and mixed the light nutrient water in a gallon to be prepared, but was accidentally feeding the seedlings the nurient water. It seemed a bit too much, I started feeding them regular water 3 days ago when I noticed. The light I have right now is at 40% strength. I'm going to kick it up a notch to 60% to give them a bit more light to grow. They've all been growing slow as seedlings I think because I gave them nutrients instead of straight water. I've been giving them distilled water. We will see how it goes in the next week!
