Planted straight into FFOF, from what I’ve read I’m under the impression the soil has enough nutrients to carry these into week 4/5, these sprouted on August 5th. Spotted these two spots yesterday and they have progressed overnight. Read all night yesterday on what it could be and I’m totally confused now, but I have found a few pictures that looked like it was pointing to a cal-mag deficiency. I have been watering every third day, that seems to be when the pot is light and the top inch of soil is dry, each pot gets 1 gallon which gives me decent run-off to test PPM and PH from. I just watched a friend finish his first grow and he chased deficiencies from 4 weeks in to the end, so I’m paranoid I’m at that critical point and don’t want the issues he had. Hopefully the pictures I’m about to attempt to post work…


Plant looks fine to me, maybe could have been water drops?


Thank you, I was unaware water droplets could cause something like this, then again I’m unaware of a lot when it comes to this, I’ll have to research that.

Yep, probably water spots, welcome!

Water drops can act like a magnifier lens with the light causing burn marks.

The spots have not progressed and everything seems ok so far, I guess I have to be more careful when watering, thanks to all for bringing this to my attention.

Now on day 34, I think this is “Pre Flower” they are getting very bushy, I’ve read about defoliation and think I could probably benefit from it, however I am wondering if I am too late because of the stage they’re in now, don’t want to cause any stress and hinder growth, thought’s?
