The medium is coco coir and I’m using General Hydroponics which is what Coco for Cannabis recommends when using cocoWhat is the medium? What nutrients are you feeding?
Started outside, we’re working on creating a grow room now for the next round.was that started indoors and moved outside?
As far as pH, both threads on here, cocoforcannabis.com, and other internet searches say 5.8-6.3 is a good range to get the maximum benefit of nutrients. It seems like most go 6.0-6.2 for the vegging state and stay around 5.8 for flower.Did someone tell you 6.1-6.2 is right? Usually soilless is lower, especially in veg. But, coco may be different.
Are you using 3-part Flora series? Are you following a schedule? Which one? (Or, how are you much of each bottle are you using?).
How often do you water? (You feed each time you water?).
It doesn't look underfed to me. If anything, you're pushing the max. You might back down a little.
For nutrients I feed every watering: I mix up a gallon and feed twice a day (usually around 8:30am and 6:30pm). I use the 3 part flora series along with Armor Si/CalMag/Rapid Start/Diamond Nectar. I follow the low end of a chart I found for General Hydroponics nutrients series.
The leaves feel paper-like and have raised ridges between the veins. Was I mis-interpreting that as underfed?

That’s possible. I may try lowering my pH a bit and see if that helps.I don't know much (if anything) about coco. I just googled and the first thing I looked at said:
"Plants grown in coco coir need a pH level ranging from 5.5 to 6.3, depending on the life stage of the plants. Normally, pH is adjusted to 5.5 – 5.8 during growth and 6.0 – 6.3 during bloom, which helps the plant to assimilate the most demanded nutrients at each stage." -- https://www.alchimiaweb.com/blogen/grow-cannabis-plants-coco-fibres/
That's how I remember using peat & perlite. I think it had to do with the nutrient availability chart, and making different nutrients more available in flower.
I don't know if that could be affecting you. It just stood stood out to me in your first post.
I haven’t seen this chart. I’ll post a picture of the chart I found on the coco website that talked about how they use nutrients. Could this be nutrient burn? I read that if a plant experiences nutrient burn that the plant may be more sensitive to high concentrations and to go slow.I haven't seen the low-end chart. Using the chart on their US website (and the 3-2-1 schedule printed on the bottle), I figured out the NPK ratio that results. GH Flora series is pretty high in K during veg. (That's why I asked how much you've been using of each bottle.). That could have something to do with the leather-leaf you mentioned. Overfeeding could do that too. (Maybe both.).
It doesn't look underfed to me. And, you said you had some burnt tips (which is in the overfeeding direction). Usually people err in the direction of overfeeding. So, I don't think it would hurt to cut back and see how it goes.

I was also following this schedule with added cal mag and ran into nute burn I cut everything in half and it seems to be helpingI haven't seen the low-end chart.

Have you had pH fluctuation?As far as pH, both threads on here, cocoforcannabis.com, and other internet searches say 5.8-6.3 is a good range to get the maximum benefit of nutrients. It seems like most go 6.0-6.2 for the vegging state and stay around 5.8 for flower.

That’s good to know from someone following the same schedule. I backed down on my EC and all my new growth seems to be doing wellI was also following this schedule with added cal mag and ran into nute burn I cut everything in half and it seems to be helping
My pH has been pretty stable it sometimes varies by 0.1 (it might be 6.1 one feeding and 6.2 the next). I pH all my nute solutions to 6.1 and check it before I feed.Have you had pH fluctuation?
