i dunno... are you sure this is overfert? what are some other possibilities ? the spots are whats worrying me, I thought burn started from the edges but these leaves develop spots first then turn brittle...
thanks anyone

Do another flush NOW. Check the runoff pH and flsuh with water that is adjusted to compensate for it. There's a sticky at the top of this section on that.
Something BAD is going on. Either you have some of the worst overfert I've ever seen, or your pH is way off- that surprises me, because with pH problems they seem to creep up slower, and you say this was quite sudden. What is your water source? What is the pH of that water, and of your runoff? What are you using for soil?
Fill out the troubleshooting form. But before you do that, flush. You MUST get your soil pH to ~6.7 and clear out any excess ferts. How much guano did you use, anyway? You never answered that earlier in the thread, and it's kinda important...
The object lesson here- ferts which are meant to slowly release over time will release MUCH MORE QUICKLY at higher soil temps.
The bacteria which make guanos available to yer plants reproduce and metabolize at a rate which is temperature dependant- the hotter, the faster.
Couple that with the inverse relationship between temperature and maximum tolerable soil or nute EC, and ya can cook stuff muy pronto.

her temperature's rising ( but any idiot could see that)

This kind of experiance is necessary for her learning..."
( Sorry, Eno on the brain- never listen to Warm Jets first thing in the morning...)
Ya might be able to flush them back to health, but I'll bet the rhizosphere damage is pretty gnarly.
Coco is my medium and I didn't use that much guano. way under its rec dosage. I sprinkled a tbsp across the top of the soil. I had been giving it 35 ML of PBP / gallon and the recommended dosage of LK (cant recall offhand)
The water is R/O and I am unable to check the PH, I will pick up something today for it.
I am growing it in my PC and the temps have been fairly stable at 78-82
The top of the main bud has turned brown.. Although it doesnt seem to have gotten a lot worse. just the leaves that were affected are browning and dieing off.
My hands are tied right now if fixing her requires a bought product.. :(
Coco plus RO water means you are no doubt having outrageous calcium uptake problems. You need calmag right away. Coco has NO soil buffering capacity to speak of, and it's technically a hydroponic medium. You'd need to be adjusting your watering solution to pH 6.5 at every feeding, and I believe (could be mistaken) that PBP is nicely buffered for soil applications. You are kinda trying to put chocolate sauce on a pasta salad. Coco already has calcium scavenging issues, and potassium leaching problems, and if it was cheap coco should have been flushed first as well to remove salts. You have to treat it quite differently from soil. It's not as forgiving as one might expect, although if you treat it like coco shoudl be treated from the start (6.5 with calmag in the juice), it is a nice way to grow.
Next time you have an issue, it would help to fill out the troubleshooting sticky the second you notice problems.
I have been giving it calmag from day 1, maybe I should be giving it more because coco and r/o?
its botanicare cocogro, and i washed/flushed it very well to remove the salts
I will pick up the ph indicator today, but the buds are continuing to swell and the smell is coming back (the buds went smell-less during the 2 problematic days)
I am just keeping my fingers crossed, this run was just to test out coco and a hand at indoor, so tis all good if I don't yield shit and learn something
tested my ph today, and can't test my ph of the runoff until next watering because I uber-flushed it last night. ph is 7.0, but the plant is looking better...
any quick/easy tricks of lowering the ph? and if my ph is 7.0 going in it must be a lot higher coming out?
