how much is the temperature in the room? (sorry if i missed it from the previous posts) looks like heat stress, maybe nutrient stress (overfeeding), but shouldnt be the case with those ppms.

no worries man, no hermies here. those that you highlight in some pictures are just cannabis bracts, modified leaves pretty much. plant is looking great, keep it up ;)

it works the same either way. plants need few days of transcriptional reprogamming anyhow when they sense the change in the photoperiod (which itself takes few days). so i don't think either method is "better" or "worst". the argument that in nature light transitions gradually does not hold much...

this. in few months i bet we will have witch doctors selling their electro-plant stimulators for big bucks rofl

plants do not care much for chloramine. they may even benefit from it in the amount is in tap water

ascorbic acid does not promote "growth" per se, but promotes more plant stretch by interfering with the cell wall. for cannabis cultivation having a more stretched plant is rarely something you want to have, because it takes up a lot of space and the stems are less resistant if you have heavy buds

the brown spots won't go away, even after you add the cal-mag. those leaves got damaged and that's it. however you shouldn't see any spots in the new leaves.

yes, if you have different nutrient solutions, you could try first foliar feed iron, wait a couple of days and see if it recovers. otherwise try something else like sulphur. i wouldn't know other deficiencies that look like that to be honest

add the cal-mag, forget the ppm

have you tried the epsom salt stray, or a ca-mg supplement? could be Ca

not magnesium or calcium. looks like iron or sulfur deficiency to me as well. is quite diffused in the whole plant so the medium is definitely lacking something. is weird because you are using iron booster as well, and ph should be perfect for iron absorption. maybe try to change nutes ever...

yes, that is exactly the issue. in one grow i had to do the same because of necessity (fan and extractor on a 12h timer). and that was the time when this grey fungus showed up, cause in the night humidity was going up like crazy. at least the extractor needs to be on 100% of the time if you...

they are fake seeds, not hermie. your concern would be if your plants would start making pollen sacs or bananas, and then ruin all those beautiful top colas you shoved. however if you are really concerned you can just cut that part away. anyhow is just a small popcorn bud. or you can keep them...

incredible pheno. was this an auto? and you said they all came from the same root? could have been an embryo developmental aberration

powdery mildew is not a mold. is a plant pathogen. mold don't cause damage per se, but if it is on your cured buds it lowers the quality a lot (to the point of throwing them to the garbage :D)

you can recover it and smoke it. but be very careful when you cure it. because you can get another kind of mold when curing as well, and that would be worst. i got one harvest with this "mold" in flowering. cleaning it and fixing humidity made it not to re-surface again. this one in flowering...

doesnt look like hermie, just swollen calix from a popcorn buds. maybe with a bigger picture...

well i am no expert on that, but that depends on the availability of agricultural shops in your town i guess. even going organic you stll need specific pesticides i think: those pests are quite annoying since they are buried inside the leaf. i dont think any household product will do the trick...

ok that looks worst :D those thread-like white areas look like leafminers, a common plant pest https://en.wikipedia.org/wiki/Leaf_miner the brown areas around could be the plant defending itself, or the damage done by the pathogen. i'd look around for some treatment for the pest.

how much is the outside temperature when you took the pics? plant leaves gets normally droopy like this in the hottest hours of the day (usually around midday). is nothing to worry about, plants do it to avoid too much loss of water during those hours
