So this is my first grow, 5 weeks in everythings lookin good, got 4 plants each under 23w CFL's 75-80F,25-30% humidity, 18/6 timer, yesterday was feeding day so when i checked them i saw that the top leaves were nice and perky but the bottom ones were starting to droop and looked sad so i figured had something to do with the lack of light to the bottom leaves, went out and bought 2 sheets of Mylar, 1 for the back wall and 1 for the back of the door, put those up to reflect the light down onto the rest of the plant, the bottom leaves are now back up and lookin happy, except for 1. I saw this little change in pigment on one of my leaves on my bigger plant, its no where on the rest of the plant or any of my other plants, just this one leaf. i was wondering if this is something i should be worrying about and if so how i can i stop it early? or am i just paranoid?image1.jpeg

That looks like some sort of mechanical damage. Did the leaf possibly get pinched between something real quick? Are these from seed? Your clone or someone else's? I'm curious to what all those white pin prick spots are that are on all of your leaves....

From Seeds, the white spots is just dust, i put a fan on them and it blew right off, from my knowledge i dont believe it got pinched between anything, its a possibility. i saw the white stuff yesterday, i have a spray bottle of water just to get the plant moist sometimes and when the water evaporates it leaves that white residue. should i stop spraying them? i read a forum that said its goo for the plants once in awhile

If that leaf was too close to the light it could cause that (what looks like a localized Mg deficiency). I had that problem a few days ago. You can see it in the top-down photos on subsequent days (after the leaves matured).

It could be damage. The way it's close to the rim of the container might have something to do with it. I get marks on my leaves there (from grabbing the container and catching a leaf under my thumb.).

I've had the same problem for years on occasion. It's like the top layer of the leaf gets rubbed or eaten off. I'm ruling out bugs though, being as that it happens in patterns. That and I don't see any bugs. The only thing that I could even really consider is that the fan blowing on it might be the culprit. Idk for sure though.

Okay but overall nothing i really need to worry about unless i see more leaves like it. Thanks for the feedback, if it was something serious i wanted to catch and fix it early rather then destroy my ladies.

Well like I've said, it's happened on and off for years to my girls. Especially my kush plants. It hasn't seemed to have caused any major problems for it though, so I just ignore it.

Appears to be pest damage. Can you get a pic of the other side of the damaged leaf and a couple more of the plant/plants?

Yeah those white spots are likely just evaped water residue. What type of water are you on btw? Mite spots don't blow off. Mites do, but those likely aren't mites.
Gotta go with whoever said mechanical damage though, because I think that could've been caused by light burn caused by spraying.
Otherwise i think it's a nute issue in which case ask me again in 4 years when I feel confident.

i simply just boil water that way its a balance ph, put it in a spray bottle and let the spray bottle cool to room temperature and just use that. ik for a fact its just water residue, was looking at it earlier and it just blows right off.

Here's a tip, ditch the sprays bottles except for the occasional teas and foliar feed. Water continuously sprayed on the top of your leaves will eventually close the stomata. In other words, overwatering.
Remember when you do spray, get the bottoms of the leaves good too.
Then remember to rinse off with clean water.
Don't go any sooner than 7 days with foliar applications, as that's a safe zone I have had.

I'm kinda thinking it may be ph related. I've had problems with using peat as a base for my soil before. The ph takes a dive after awhile due to the peat breaking down. Once I corrected that, the problem goes away for the most part.
