Did you happen to get any fertilizer or water on the leaves this could do that to them also. the liquid on the leaves acts like a magnifing glass and will burn them. Unless it was the calmag its not organic.
Nope and I understand where you're going with this. Large percentage of affected leaves aren't near water sites so I'm pretty sure I'm good there. That's not to mention that the problem has become worse..

i could be WAY off here but it kinda looks like they are being over watered or have 'wet feet'. if so and they suffered nute burn, personally, i would have dispensed with the heavy waterings and just flushed them- letting water run through the soil mix freely for 10-15 mins ea- similar to if we burned our own hand and ran it under water for 20-30 mins... then let them recover from the nute burn for a few days-week feeding with water only when the top 1-2 inches of soil became dry.
I went ahead and flushed it 4 days ago. Ran 3 gallons of declorinated tap through the container outside and took it in later. But I'm at a bit of a loss at this point because the problem has deteriorated..
I don't believe I've been over-watering since the beginning. The Black Gold retains well but I've been doing the 3" rule when checking and that's been bringing me in at a feeding cycle of 7 days since the first pot, which doesn't seem excessive. I'll give the leaves a spray every few days and I don't foliar feed nutes.
Well, here is how she's looking now..
1) Entire plant now seems to be affected 4 days after "flush".
2) New growth coming up with brown tips (this is the first time this has happened throughout growth)
3) Light pasty green spots are present but others are starting to turn brown
4) Quite a few old and new growth is deforming and shriveling up regardless of size
Right now I have her in a closet. Temp - 75 / rH - 70. Soil temperature has been a bit cold since the flush. Don't have a soil thermometer right now.
So it looks like I either have nute lockout (phosphorous), nute burn or both. I took a look here:
Nute Lockout and I'm going to try and shock her to shit by re-flushing with a leeching agent. I'll give it another 3-4 days, water and then begin phosphorous treatment. I think I'll skip the superthrive piece of the treatment.
Questions
- I realize soil medium grows don't react quickly to change. How soon after a flushing could I expect to see a change in plant (bad or good) grown in soil?
- If it's phosphorous problem should I address that now or wait until after leeching to add nutrient? It seems to me if it's a deficiency I should take care of what might be causing the def first and then treat.
- When leeching, should I loosen up soil in the pot first or just run the agent through as the soil is now? I don't want to shock the plant any more than it has already been....
You know, I didn't realize that this little experiment of mine was going to be so challenging. It seems ridiculous compared to other indoor plants I've worked with but then again, maybe I'm approaching it with way more sensitivity and I'm doing more harm than good with over-modifying this and that. It's almost as if I'd be better off if I just threw a few seeds into a balanced fertilizing soil and just watered it for three months...
Anyway ..thanks again for sharing all that expertise.. your help is much appreciated!
and ive grown with them for 20 odd years now with no probs ;]
