WHAT IS THIS

I don’t know what this is please advise

Got a very similar looking thing going on rn that I just posted about too

Can you share a full plant pic and the details of your grow?

What's your pH?

Using LED?

They are a month old they’re in 2 gallons of pro mix, bush doctor coco loco, and foxfarm potting mix. I don’t mess with ph really, bc my tap is I think about 7-7.8 and so after I mix nutrients with my water it balances out. I don’t know what ph I give them but I messed with adjusting and testing ph before and I’m not interested in doing that if I don’t absolutely have to. Pics in a. Bitc

It looks like the leaves were touching your medium when watering

Here are pics of the clinical white CBd and the sour diesel both a month old as stated above

And I have some plants in flower and one is further a long I’m not sure if these spots popping up on my big lower fans leaves are because of the age and process it’s going through or what but I’m not real worried either. By the way check out my grow journal and give any input you feel like.
