What is on my fan leaf?

[GreenMachinee]

Hello everyone... a few of my fan leaves on two different plants developed these spots overnight... the one pictured is the worst of them all and there where only three fans leaves affected total...

I do not spray anything on my plants.

I just realized I said the H word in the title hahaha I hope I didnt break any rules with that... Im sure this site is meant for adults right? Tried editing it out but cant figure out how to edit the title. Sorry about that

looks like you got her with some nutrients when you were watering

be careful to not splash her with nutrients and you shouldnt see any more spots.

i typically ignore any random spots similar to that unless it looks like its spreading and im 100% sure it wasnt me.

Thank god thats all this is!!!!!! hahaha normally I am so slow and careful when feeding... Guess i got a little too comfortable. Thanks nibec!

 

[nibec]

just be really careful when feeding and keep an eye out for new spots just to be 100% sure.

but either way, looks like all my lower leaves... im shaky..

 

[GreenMachinee]

Looks 100% like a critter such as a caterpillar to me. They will eat the chlorophyll right off the leafs

definetly not a caterpillar. they eat holes in the leaves

This has just taken a so sinister turn lol

 

[GreenMachinee]

Hopefully not any kind of critter. Ill keep an eye on it but im very attentive and have not seen any critters. I check daily

Did you take those out of a humidity dome a few days ago?

I've seen this a few times and I don't know exactly what it is or what really causes it but it happens to my seedlings and clones sometimes when I remove them from my humidity dome and transplant. After seeing if a few times I realized when it was happening I think it's due to drastic humidity change. She went from a 80% humid environment to a 40% humidity grow tent and then a few hours later she had a few transparent spots. A day or two later they turn brown. I had a close friend suggest harding off my clones and seedlings before transplant. It involves opening the humidity dome a little at a time to change the humidity slowly. I imagine if your grow tent was humid and you aired it out with a quickness you may have caused these spots in a similar way to my issues. I may be wrong but from my experience it doesn't spread..

Your very welcome... P.S, Luv your grow journals

Thanks twox this could be as my humidity was about 70-75 in my tent and i quickly brought it down to around 40 by adding more airflow

 

[GreenMachinee]

But whether it is rapid humidity change or nute splash im glad that it is not spreading and my ladies seem nice and happy
