Some of my fan leaves are starting to taco slightly. should i be alarmed and do you guys have any suggestions to fix the problem?
Plant has been in soil for 11 days so far ..

im in a hot climate and avg temp is 85-90
have decent airflow and humidity is fine
a google search brought up silica as a fix?

It looks fine. The temp sounds a little warm, could be from that. Its usually nothing to worry about unless they are all rolled up drastically.

Where are the tacos? I made guacamole.

Silica would help, if you don't already have it in your soil or your feed. Do you have good drainage in that pot?

As a precaution hit it w a solution a 1tbsp epsom salts to 1 gal water, weekly.
I see no purple. Or other indications of mag def but i have seen early mag def present as tacoed leaves then the interveinal yelowing follows a week later.
in any event a spray of epsom will do two things: create higher rh around the leaves and arrest any possible deficiency before it gets worse.

i wouldnt spray for any deficiencies that dont exist yet. You may start agitating the plant and make it start showing nutrient lockouts that look identical to deficiencies. Ive seen too many people use calmag when it was not needed that simply forced the plant to lock out calcium or magnesium. As the plant does this it will yellow up causing the same person to simply keep adding more calmag until he finds himself harvesting plants that do not have any fan leaves left on them from being burnt off. Some think this is normal and simply say that their plants just eat a lot of calmag. Calmag deficiencies in my experience are not as common as most would have you believe. If you are using a soil less mix you need hydro nutrients being that they carry plenty of calmag. Soil nutrients hold back on the calmag because most soils will have lime or the equivalent. In hydro, most suffer a magnesium deficiency due to most hydro growers maintaining low constant ph of around 5.2-5.8. Instead of letting the ph swing up to 6.2 and readjusting back down, they tend to start foliar feeding calmag, which will remedy the MAG issue but by doing this they may overload on Cal. Nutrient absorption is best controlled by letting the PH swing a bit in either medium to allow the most even absorption rate possible all across the nutrient uptake scale. If you dont let the ph swing certain nutrients will not be used by the plant efficiently causing an overabundance of the nutrients in your medium. Your plants definitely show heat and humidity stress. It is hard to work with high temps. The only way to really do this is in an enclosed room using CO2 and regulating humidity and temps.. In a non enclosed room with a lot of ventilation your plants have problems retaining moisture which is the taco effect you see. Its simply trying to hold every bit of moisture possible on the leaf surface. It rolls up to trap the humidity. Also the pants seem hot (nute overload). With real high temps the plant will attempt to suck up more water which means more nutrients working through the plant at any given time

So what are my options to reverse this affect? try to lower temps?

i have mine sitting right now on about 34c with the lights on about 26 lights off when i hit peak summer were i am there is no stopping the heat lol air cons do shit they will be fine few things u need to do is back off the nutes also get more then one fan for maxium airflow also when u feed go a fresh water feed then wait an hour then give them a nute feed i dont no why but they tend to hate straight up nutes on hot days

If you can lower temps, that would be the best. I knew someone once that set up a misting station inside of their grow due to temps like what you have., but it was very complicated and common sense told me dew and humidity flying around like that only helps things get hotter. I personally would try potassium silicate. It is supposed to help with higher temps. Not sure if it will cure your taco effect, but would at least make sure you see your grow thru by providing you with a much sturdier cell wall structure along your stems. I used to use house and gardens amino treatment which has it in it supposedly even though it was not listed in the ingredients, but never used it for the silicate as much as i did for everything else that was in it. You may want to talk with someone who is growing in high temps. I know its possible. It just becomes much more of a challenge. just remember plants burn(nute burn) easier when running them in high temps

Dont need so much nutrients this early in growth. A simple cal mag supplement with a 1-0-0 npk ratio is all u need for first week or so. See the crinkling of the leaves n how dark they are, too much nutrients give it water a few times u will b fine.
