Slow Growth Nerves?

Hello all. I'm sure I'm just overly nervous as this is my first grow. It seems to me from some other pics I've seen posted that my babies are growing a little slow. The pics attached are 3 weeks from seed and are growing in Pro Mix HP under a 4' 6 bulb t5 HO up in my attic. It's been pretty hot lately and maybe that's the reason. They are a mix of 5 Wonder Woman and 4 bag seed. The average temps up there have been between 80 and 95 degrees. Is this what's causing a slow growth? Ive been running the light 18/6 with a 6" inline intake and an 8" inline exhaust with a oscillating fan. Last night was the first nutes I fed them using FF Grow Big with a water PH of 6.8. How long before the nutes take effect and should I have mixed in the Big Bloom in with the Grow Big? Any feedback is greatly appreciated!

Thanks and I look forward to finally being apart of this forum!

Why are you running bag seed with Wonder Woman. Are you breeding? You run the risk of pollinating your Wonder Woman. Are the Wonder Woman females or unknowns? Good luck with your grow Dude. They look okay. A little too hydrated maybe. Does that ceramic pot have drainage?

First of all, sunlight is very good for a plants growth. The reason why your plants are small is one of the following: Use a bigger pot with drain holes. It gives your roots room to grow. Its an indica strain, so its not gonna shoot up like a sativa breed would. Your watering it maybe a little too much. Wait until the soil drys up, kinda crunchy like and about 3 inches deep. I use gatorade bottles when i water them. Dont use your super bloom stuff until its time to flower. Use a veg nutrients, I use MAXI GROW 10-5-14. Use nuts like once every three feedings. You dont wanna use alot either. Dont risk giving it nut burn. Any other questions id be more than happy to pass on my knowledge to help a fellow grower, best of luck bro

Hey bluastoner, damn, I didn't even think about cross pollination. When would that start? is it too late to separate them? I do know that bag seed was really good OG Kush, though would it cause an issue? The ww seeds are unknown. Yes, I have a few large holes in the bottom of that one ceramic pot. Trying to work with what I had around the house. I took these pics just after watering.

Thanks for the input! I think I did get a bit over board on the watering. I guess I figured since it's so hot up there they'd need it. Should I be misting them with a water bottle? I tend to do that each time I go up there, morning and night.
