Leaf deformation and mottling in young coco grow

The mutation is called variegation and can look like a typical one of a sectorial chimera. It can happen with ingrown genetics and not so stable lines where the mutation was present in the lineage It's mainly visual and it doesn't often mean that the plant will have more problems, it will just look funny But sometimes the plant can get sickly due to structure and yellowing spots not being fully able to absorb light and photosynthesis leading to slow down growth Start over or keep it as an experiment, up to you. Good luck on your grow :)

Looks ill. For sure some deficit in the newer leafs (and in the middle of the older). Looks like the plant took a sip of poison or bad water. Maybe virus/bacteria at the roots?

Some seeds just don't make it..............this could be one of those that does not.

Hey, thanks for the detailed info that helps a lot. From my experience, coco tends to hold moisture quite well, especially in smaller pots like 1.7 L. 250 ml once per day might be a bit too much at this stage. I usually just check with my finger daily to see if the medium is actually drying out. In general, less water is often better than too much early on. The symptoms you’re showing twisted and slightly mottled leaves look more like a combination of mild underfeeding and a bit too much light stress rather than just a watering issue. Your EC at 1.0 might be a bit low for coco, especially since coco doesn’t buffer nutrients like soil does. Also, your VPD range (0.7–0.9) suggests your humidity might be a bit on the low side for this stage, which can slow nutrient uptake and add to the stress. I don’t know your exact feeding schedule, but I’d recommend adding a proper root stimulator like ATAMI B’cuzz Root Stimulator that stuff works really well. On top of that, your plant could probably use a bit more nutrients overall, especially calcium and magnesium, and possibly some sugars/carbs depending on your line. So I’d look into slightly increasing your EC, dialing back the watering a bit, and maybe raising humidity slightly. That should help stabilize things. And don’t worry this is nothing dramatic. The plant will grow out of it and you most likely won’t notice anything in the final result. Hope that helps! Terpz😊

Did you buffer your coco with CalMag before the grow? I use 1 part coco coir with 1 part water with 2 ml CalMag Agent per liter with pH 5.8 and let it soak for 24 hours before grow to prevent this issue. I am not a big fan from the CalMag Agent due to the high amount of Nitrogen but for the buffering and grow phase this is great stuff! The GHE CalMag is better for flowering phase because it doesn't contain Nitrogen. One small explanation why buffering coco coir is necessary. The coco is absorbing and not releasing the calcium. That is why you need to buffer it first otherwise it will take all the calcium and there will be nothing left for your plant.

Looks liek more of a genetics issue unless your coco is unbuffered / unwashed,. even then salt sickness would look different. That vpd is a bit low for a mature or nearly mature plant. If that VPD is calculated based on air temp, then it's even lower than you think. I wouldn't go below .9 based on leaf temp (proper measurement of vpd). That can cause leaves to curl in on themselves, but the damage on the leaf shown could be mutation, or possibly something dripped on it as it formed but looks too spread out for that... I really dought a 1ec could cause serious damage, if anything it's slightly underfed. irrigations habits are simple for coco coir - same as any other soilless medium. Coco is not magical and does not require any special treatment. If coco ever causes a problem in regard to calcium or anything else, it is poorly buffered, which is the manufacturer's fault or you bought unprocessed coco which is at least dangerous and can be lethal to plants. If you ever find inconsistencies with your coco coir product, buy a different brand next time. Based on your description, it does sound like you are watering wrong. You don't pick the volume. you give what it takes to accomplish the task. unless that 250mL is enough to cause 10% runoff.. and allowing enough dryback for a healthy rootzone. 1) always fertigate with 10% runoff or more -- the runoff is essential 2) wait for appropriate dryback and repeat. With coco, when that top layer starts to change color, that's a healthy wet-dry cycle. You can trigger sooner, but i'd get thos roots properly grown before any increased fertigation. In soilless/hydro symptoms are fixed through formula adjustment, since you provide 100% of nutrition. Runoff prevents buildup - a consistent level of nutes exist around the roots. Any leaf symptoms seen are fixed through the formula.. take notes. this stuff doesn't happen over night. it's a culmination of everything you do from day 1. feeding heavy early will required less later, for example. Check out dr. photons corner on cocoforcannabis.com. Best information based on facts and not anecdotale extrapolations of desperate people wanting to feel special because of their esoteric growing methods. Ther's no secret method with phenomonal results, lol. So, if deviating from that, fix it.. could be a contributing cause. The plant pictured here looks like more of a genetics problem, but if new growth starts to look healthy, it'll grow out of it. A good formula will work on 95% of plants. A lot of the perception that this plant is picky or difficult to grow is a matter of self-inflicted error and not looking in the mirror when things go wrong. With an indoor plant, kinda hard to blame anyone but ourselves when things go haywaire, lol. maybe, it was the boogey man? It couldn't be my overpriced fertilizer that's 'specially made for marijuana.' LOL This may or may not fix things, but will allow for easier diagnosis once you eliminate caueses involving poor watering habits. pH swings can cause twsited growth, but if your pH is relatively steady, that's obviously not the case.

Hey! I’m not 100% sure, but it doesn’t really look like a watering or EC issue to me. In coco I’ve seen people mention that this kind of twisted, mottled growth can be related to CalMag, especially early on since coco can lock it out a bit. Maybe worth trying a small amount and seeing if it improves.😇

Did you spill some feed on the apical, it's threw nute burn, either fed too much or left a drip of some hot nutes on the center.. That's my opinion mate
