First sign of preflowers, Day 17

First grow and I have some questions regarding preflowers. I recently noticed from some pictures that my plant has what seems to be some preflowers growing. I can see the stipules, but am looking for advice on my preflowers (if they even are). Thanks guys and sorry for the bad picture quality, I will try and get better pics for ya to help me with. Are these preflowers or what?

from the pic its hard to say yet, if its a female calyx, the little hairs will come out, but they will first be behind the stipule, if its off to the side of the stipule, thats a common sign f a male preflower, but how long are you in the grow.

Hard to tell man

Thanks for the responses guys, sorry the picture is terrible, il post a better one when i get home.

That's the thing, there only 2 weeks from sprout, 17 days from seed. Ive heard of preflowers showing this early, but seems It's rare

take it easy for a few more days:then, the flowering stage begins!. have fun. GL

thanks guys, While were all here it seems i might have the early stage of a deficiency again! ughhhhh more and more problems. Im sorta liking it though because im learning a lot. I love knowing if this grow doesn't succeed, I will have that much more knowledge going into the next. There is some yellowish/light greenish in the center of my new 3 leaf set. The leaves are curling due to heat stress (which I am trying to fix) but having issues. Since I am pumping CO2, Im trying not to run the exhaust fan. I do not currently have a light cooling system, so my temps creep up to 85 sometimes, reaching 90 once. Im keeping the humidity around 55% to try and combat the heat, but they're not liking the heat too much. Should I cut the CO2 and worry more about the heat, or is this something that is not that big of a problem? Ive read that CO2 helps them manage heat better but this doesn't seem to be the case with this strain (bubblegun).
