weird color on new leafs?

hello guys
i just bought a LED panel and noticed that since i started using it my new growth has a weird brown/orange color..
i thought it was the light so i shut it off and looked at them in normal light but they still have the weird colour.

anyway, here's some pics:





also are these little nubs preflowers starting?? they sprouted june 10th and 13th!



and here they are together




thanks for the help!
i dont think i coulda done it without RIU!

Completely normal, it's got some purple in them.

normal
what strain ?

they were pretty purple when they were young and have very red/purple stems and i know its not a deficiency cause i have been feeding them with 20-20-20 food and a teaspoon of epsom salt in their water.
its pretty weird how i added the light and they start doing that lol
i dont know the strain, they were "indoor mix" from the seed bank
thanks for the help

your temps dropped ?
that usually does it
some times they just cant help it i have a purple haze that has done it since its first set

temps dont go below 25°, mostly around 30°-32° cause its been realllly sunny and hot out lately.
im looking into getting an ac cause its too hot for me, they have fans blowing over them and seem to be enjoying the heat.
i really dont know what caused the change.
maybe they like the light better?
im going to flip them on friday im thinking or i might just wait for preflowers so i can clone a few.
i dunno!! im just hoping my pots will be big enough

My seedling looked the same for a little while...



Almost like a grayish purple brown color. Mine turned out to be caused by low temps I beleive... my temps were in the mid 60's at night and being a sativa dominant strain I think it's more accustomed to higher heat maybe? Don't know... but I added a few more bulbs which raised the temp and the weird color quickly disappeared.

for me its just the new growth, im thinkin my led's are too close, im going to lower my plants and see if that helps ,its deff not temps though cause 30°c is warm

nice little one in the pic!!

... nice emoticons!! do you have something to say to me or are you just going around copying what people say?
lets hear your advice if you're so smart buddy

your not gonna see preflowers till you flip them to 12/12 for like 2 weeks. there are tricks to find the sex early. like take a lower branch and put it in to 12/12 and check it for sex. those are just future branches.

i have seen people with plants that have preflowers in veg, they start at 6-10 weeks depending on strain
i was told the last part but i deff have seen preflowers on veging plants.
thats a really good idea about the branch thing!!
such a simple idea, why didnt i think of that lol
i flipped them yesterday so it will be soon
yay!
