Was wondering if this is spider mite damage or time to add nutes? Seen this today.i havent added any thing yet but water. Growing pineapple chunk 3 weeks old yesterday. Dont really know when to start adding nutrients. Any comments or help?

Probably nothing but check the back of the leaf for mites. A 30-60x loupe is handy for this and checking trichomes. . You shouldn’t need to add anything to FFOF for a long time. It should carry you through veg at least.

Are those leaves near the bottom @Drewdash420 ?? Sometimes the leaves on the bottom get splashed when you water so no big deal. Still, get a loupe like @Merlin1147 says. If you do have critters you'll see them moving and know right away.

You want the loupe anyway. Great welcome to RIU right !!

Yes it's at the bottom. No more has spread so far. Got a 30x60 loop. Didn't see anything. But I did see a little white fly on the plant and i smashed it. Do you think that might be the culprit? There was only one. But do I need some sort of spray to repel?

That's the suspect right there. Also I have off topic question. Am i supposed to be running both veg and bloom lights on when I'm growing autoflowers. Im on veg right now.

Check again on the under side of the leaves for something that looks like this. Almost translucent and really small. You may want to get some yellow sticky cards and put one or more in the tent. The adults whitefly will be attracted to them and you can see if you have a problem or not. It may have been just a lone flyer. Probably not, but don’t over react. A lot of growers have smokes their plants (in a bad way) applying all manner of crazy solutions to rid imagined problems. I’ve never dealt with whitefly on weed but I’m sure someone here can help if it becomes necessary.
As for the light yes both on.

I should rephrase the light answer. I don’t do autos but from what I’ve read yes both on. Others with more experience with autos may have other advise.
