First real grow..spots on leaves

hey guys. This is my first "real" grow using a decent little setup. My biggest plant started getting small spots where it looks dry for lack there of. I've done research here on the forums and have come to a conclusion but was wondering if I could get a second opinion on it.
There sitting it happy frog soil
They are 2 weeks old.
Have not started my nutes yet(tiger bloom)
Watered with ph'd water between 6-7
Using two 300 watt led lights.
Fan allowing for good circulation.
They did get a little hot for a few days when I was still waiting for fan to show at my door(highest was 92 degrees)
Any help/suggestions would be awesome.

What's going on with your intake & exhaust layout? If fresh air is coming from that opened port in the top left where your wires are coming in and being sucked out at the top right, you're not accomplishing much plus you're not encouraging much air movement around the plants themselves. The point is to draw cooler air from the bottom intakes up and out through the scrubber. Also, hooking up your scrubber after you're in flower will be a nightmare. You'll have to pull out and potentially damage your plants so get everything square now.

Thanks for the reply man..the top right port hole open with wires coming through is most always closed unless I'm fidgeting with wires. I have a hole in the bottom with a piece of dryer duct in the shape of a half moon setup as to not allow light to escape. And thanks for the advice on the scrubber. That makes a lot of sense. I will connect all as soon as possible.

Sounds good man, yeah your plant look very healthy aside from the spots. If this is your biggest plant I'd hazard a guess that you might be showing some deficiently due to needing to up pot, not because anything is actually needed. It's looking mighty hearty to be confined to a cup.

What strain is this? I'd highly recommend against tiger bloom anytime soon, especially if this happens to be an auto. Did someone tell you to go with a bloom nute while in veg or is that just what happened to be available wherever you went?

Hey I meant to ask, it looks like you foliar spraying it. Is it just PH'd water?

Hey. Sorry I have big bloom not tiger bloom. I did take your advice and up potted. Seems there doing well in their new homes but it hasn't even been 24 hours so I'll keep an eye on them and update. I do spray them with ph water every morning when I wake up and every night before I go to sleep. I also think I was under watering a bit which has since been adjusted and hopefully corrected. Some of the plants had started curling their leaves a bit which I'm sure was a product of underwatering.

spots could be water spots. i wouldnt use bloom in veg state either. try to get a veg nute instead. in veg i use age old organics grow and in flower age old organics bloom.

Sounds like a heck of a lot of spraying man. The pics don't show any sings of underwatering. It's very apparent when underwatered.

I agree with to much spraying, water and light causes burns in the leaves

Very good to know. I had know idea. I will certainly spray less for sure. As of now since they've all been re-potted into larger pots they seem to be doing very well.

Agree with others, I never let water touch the leaves. I believe thats the cause of your spots.
