I’m a newbie, but one th8ng I see is your pots are way too small for that many days. I would think you need minimum twice that size or larger . So may be root bound.? Rootbound would lead to nutrient uptake problems, which it looks like you may have a couple different ones. But please let the more expert weigh in…I wanted to take a shot

I think @ReMoLu makes a good point. That pot does look pretty small for such a large plant. Also, your Ph is a little low. Looks like it could use some Cal Mag.


I’m still trying to figure out how canopy temps are no higher than 72 with 1000 watt hps at 18”. Cool tube?

those are some pretty small pots are you feeding them?


The first two pictures made me think tobacco mosaic virus.

I’ve never been good at diagnosis, but I think the problem is more than pot size and pH.

Really need the support ticket…


Im with the others pit size is small fir a photo
Maybe a fabric pot that size would be ok since they air prune root but plastic your most likely root bound
I would also increase ph to 6.3-6.8 range min 6.3 i try to maintain a 6.5 average myself afyer gently transplanting to a larger pot dont want to stress her to much in flower :wink:
As Dj asked are you feed nutrients and is ff soil ff ocean forest ?
