Hey everyone,
Just been trying to take care of this myself but I’m not getting it down.
Some of my girls have been yellowing on their leaves and slightly brownish tips.
I’m not sure if it’s the lights or if it’s a deficiency. Let me know what you think and how to fix it if you can.
Thank you!

I use FFJ at proper dilution with wetting agent. Potassium heavy. 1 time a week.
It’s not on every plant just a couple. 2 or 3 of my smaller GDP and 2 Durban poisons. Only one a couple leaves too. Not as heavy on the canopy beside beginning of yellowing and what looks like a slightly burnt tip.
I use bergmans nutrients.
I have 2 oscillating fans at full speed going at all times from AC INFINITY.
They’re around 2 or 3 weeks into flowering. One GDP is just showing signs of sex though.
I water regularly. At least once a day. I follow the instructions that the nutrients say is necessary to put in so I don’t overfeed. PH of 6.5
The canopy is about a foot and a half from the light at 100% wattage. I’ve seen a few different distances to go by at this stage so I’m trying to read the girls to give best care.
I’m not sure if I can think of anything else that’s vital.
The plant looks pretty decent. I’m not sure that I would worry about a couple of leaves with problems? Were they from the lower portion of the plant?
Can’t offer much not understanding what pH and PPM are.
The first set is of the same plant. Second sets first picture is a different plant than the other two. And the third set is completely different plants.
They are mostly on the lower portion but I’ve noticed that new yellowing has begun growing up
That looks like deficiencies.
What’s your ph?
I’ve been keeping it at 6.5 when watering. I don’t really get run off because I go by weight and use about 8 ozs of water at a time and check weight afterwards. I repeat until it feels heavy but not super heavy
Hmmmmm.
I would try and take off some of the less essential foliage first.
Looking at some of those leaves it really looks like potassium deficiency.
Maybe someone else can chime in.
I actually did just do a pretty heavy defoliation/ minor pruning to reduce humidity and open up light. Hopefully that takes care of it. I did just recently see a slight curling of the edges on one leaf of one of my more mature plants. Idk if that helps?
Thank you for chiming in!
Curling or tacoing can generally mean two things. Heat and/or ph issues. I would recommend a soil slurry to confirm your ph first. Believe it or not, alot of issues present themselves as deficiencies when its actually a ph problem. Sorta like when you go to the doc with an issue and the first thing they do is draw labs to start ruling out. We as growers look at ph first to rule it out as an issue. If ph checks out, then look at deficiencies
I actually have a landscaping company I could do that at. I will do that tomorrow or when I get paid most likely.
Thanks for everything man. I will keep you updated.
