Anyone know what could cause this

At first glance I’ve thought ph issues. Measured runoff yesterday, and i was a 6.1. Last feeding i was at 5.8 but got that up. Plenty of airflow, temp between 74-77. Humidity between 40% and 60% rh.

At first glance looks like Nitrogen tox. Downward clawing, shiny waxy looking really green leaves. Without knowing more, that would be my guess and that is all it is at this point.
Here is a support ticket. Knowing more about the how and what will help get a more accurate answer.

Experienced community members and expert staff will be better informed and more capable of providing a more accurate answer with the questions below filled out.

Nitrogen toxicity would be my 1st guess. But Yeah… The info would help.

Roughly 5 weeks old. Ppm runoff 1400, because its in ocean forest. So an excess of nitrogen would make sense.

Everything looks pretty normal on the numbers. The only thing I would do if she was mine is on the next watering, I would run some straight 7.0 3x the typical volume through her and get a ph reading after. 6.0-7.0 is pretty much where you want to be and at 6.1, not bad, but on the low end and if it tanks, nute lock could happen. I would get that up closer to 6.8 so you don’t suffer from lockout. This should also help to get some of the nitrogen out of the soil.


:+1:t2: will do. I appreciate the help. I have had issues with ocean forest and low ph the last couple runs. Might be time to make a change.

I really like the FF soils. I only use the OF as a lower layer when I transplant. I mix Happy and Coco Loco when she is young. At the 3rd pot is when I layer in the OF on the bottom and same for the last and 4th pot which is what she finishes in.
COM (Coast of Maine) is a cannabis friendly soil as well. Lots of good soil growers and living soils is something I have been looking into. U can use the FF soils and you add the Earth Dust and cook it to get it living before you use it but then after each harvest, you can reuse by adding the base again and then the boost during flower. It is a very simple water only regimen but you have to maintain the eco in the soil by not letting it dry all the way out like a normal soil with nutes type of grow.

I get pretty nice roots throughout the process. Also I have heard that a large batch of OF was released for sale at 5.5-5.8 ph. I started doing a test when I open a bag for the first time so I know if it is in range or not. Bag says 6.5-6.8. Not always the case.


How frequently are you watering? Looks to possibly be overwatered


Currently it has been 4 days between watering, but i wait till the soil is dry.

In my experience, my plants always get a little funky right in the beginning of flower. I’ve always chalked it up to being a transition period for the plant and it needed to adjust. I could be wildly wrong, but every plant I’ve ever had has done exactly that at the beginning of flower before regulating itself and going back to normal

Yeah i agree, kind of hard to mimic nature to a tee. I’ve also noticed a huge difference in these strains and what they need.

Agreed. I have an indica, grease monkey, that you couldn’t overfeed if you tried, and a sativa, amnesia haze, that gets burnt every single time. Also have a lemon haze that you can beat on and not affect anything, and a peanut butter breath that if you look at funny it will start drooping :person_shrugging::joy:
