Discoloration on leaves.

[EnduringCurse]

Can someone please help me out. I have a Samsquanch OG. 25 days old. Noticed what I can only describe as a gold smudge. It was the only leave with issue yesterday now I see a few " spots" starting to emerge. Temp maintains at 78°-82° with RH mid 40's. Feeding Foop nutrients at recommended quantity. May have pushed feeding schedule ahead by a day or two. Once or twice. Light is 22" reading 463 ppfd, 30 DLI according to Photone app. Not seeing these issues on my other plant. Not of same strain.

In HF. Night temps 72°.

Everything was looking so good too.

I try to ph everything to about 6.0. I tested my run-off and it read 5.5.

Plant looks healthy although it’s pretty dark green. So I would keep an eye on the nitrogen. Did you happen to spill some nutrients on it when watering?

 

[EnduringCurse]

Yes that's very possible. My watering can is a POS. I always go over any spots I may have spilled on with a spray bottle with plain distilled water. You think that may be it? The only thing I could think of was maybe my pH pen is off or there was a lack of nutes but that seemed less likely.

Thanks for the reply. I appreciate the info.

@EnduringCurseWelcome to AFN It looks to me like you are feeding too much too often and your RH is too low for the temp.

This is a VPD chart. Look it up if this concept is new to you. You want to be in the green zone until late flower then holding around 40% RH is a good idea.

Thank you for your reply. I have been battling with keeping the RH high enough. I'll look into some other humidifier options. Foop promises their product won't burn plants. Says it's ok to feed with every watering. I'll cut back and maybe feed with every other. Thanks again. Glad it isn't something more serious.

It can be easy to spill stuff on the plants when watering. If they’re left on they can leave little burn marks.

I’ve seen abrasions from the leaves rubbing on tent walls, tucking, etc.
