I just watered my plants today after my transplant, came back to them a few hours later and all my perlite on the top of the soil is turning a yellow/golden color

WTF is going on here?!

I set out my water for 24 hours + before I watered them I thought that was supposed to help that?

Do you think it's hurting my plants?
 
I've seen that before usually when the soil is too moist. I just carefully take off the top 1/4" of soil and replace with fresh dirt, less perlite.
 
I just watered, within an hour or two it was yellow

Why would it stain on top but not IN the soil?
 
I am geting this same effect on the perlit in my organic soil just the tops of the perlit turn golden the down facing side stays white for me. my plants are still doing great even with the discoloring to the perlit so i dont think its a prob at least not a big deal

i have yellowing perlite:

i think this is due to no ventilation/air movement so the pots arent drying out quicker... ive only used a very weak nutrient solution during the transplant, then it dryed out nice after a week so i watered it with plain distilled water and that all sounds fine to me, i believe it would be from either:

-the salts in my water - which shouldnt happen becuz im using distilled water
-over feeding- which clearly i havent done
-not enough airation - which i suspect

(sorry i stole this out of my current thread, no one answered n i was lazy, but i have no fans, just 3 walls and piece of board i put across for the 4th wall, im changing this soon i know all about ventilation and all that, but curious cuz it has happend before and it was a similar situation with no ventilation, i belive it happends when its watered aswel)

ANY COMMENTS!?
 
I have a Comment. Never think about it again, cause it's no big deal AT ALL. Not salts. I think it's from the light. Either way it doesn't matter. It's effects are no different if it's yellow or not.

either way check your ph and back off on your nutrients looks like your baby is in the start phase of nutrient burn

mine turnes yellow also, i thought the same as you. not enough ventilation, also i had bags under the 400 mh, and bags under cfl. the cfl turned yellow while the mh didnt. the cfl's were about 3 inches from soil/plants. but the mh was 15 away, getting much more air flow. after i changed my vegg box to add a little more air no more yellow perlite! woot
 
I know this is an old post but would it be better to take the yellowing perlite out, leave it in, or doesnt matter?

I've had this before and chalked it up to light and moisture. Don't worry about it, it's not hurting anything.

Not too much to worry about, perlite does this. When it turns green or brown write back.
