The bumps on the leaves look like a genetic issue.
Thanks, but I don't think so, grown this strain many times, cuttings from mother plants, when healthy they don't have this issue. I'm suspecting maybe a leaf fungus issue, but not getting any real improvement with neem sprays.
Thanks, EC is 1.0, PH is between 5.8 and 6.1. I've checked the calibration on both (even EC I don't really need to calibrate because I know from experience 40ml of A and 40ml B in 10L always comes out EC 1.0).
If everything is in check with EC and pH, the only other thing I can think of, other than fungal, would be a batch of nutes on the diluted side. Did you just crack open a new bottle of anything? New nutes, new pH adjusting solution, new bottle of cal/mag?
Ok thanks, no, everything is the same re nutes and EC and PH. If it's fungal then neem is not helping at all and I thought there would be some improvement. I'm doing a flush now, then I will try changing to a totally different brand of nutrient solution. Getting worried I'm gunna lose this strain I've had for years if this batch of cuttings don't make it because the mother is already in flower.
Thanks, small pot is just for early cutting stage, I normally transplant to larger pot about this growth stage (in fact 4 out of the 5 cuttings have been transplanted already, they are all showing the same symptoms to some degree although this one is a bit worse.) Watering schedule is 15min 4 times a day top feed, this watering schedule I've used successfully for quite a few grows. E.C is 1.0 so be surprised if it's overfed, same level as I've used before.
I posted it might be genetic earlier. I'm guessing the majority of the regular troubleshooters aren't touching this post because they aren't sure what's causing it.
Ok, thanks, here are some pictures from the other clones, slightly milder symptoms but still not good. New growth is all bitter and twisted. I'll try and get photos of mum soon.
