sneakypeak! while jammin to scorpionz, ooh yeah! ppp
Day 74: So after posting yesterday I noticed the top couple of leaves were looking bad so I ended up watering around 5L of pH 5.56/2050ppm with 1L (20%) runoff of pH 6.03/2830ppm.
There is plenty of salt build up on the pot now so hoping that the high runoff is partially due to that. The next few waterings include the PK13/14 boost and should be the highest ppms in the whole grow before I lower them again for the home stretch.
Day 74 update: So another 3L of pH 5.56 / 2050 ppm with a 30% (1L) runoff of pH 5.86/3060ppm.
First time the pH runoff has been close to 5.8 so will increase the pH for waterings back up to 5.8 but need to watch that ppm. Noticed another couple of leaves with early signs on leaf damage. Not sure if they were like that before and I didn't see it.
Watching her like a hawk....
Wow, that EC is crazy high,... so much so that I have to wonder about it's calibration accuracy,.. I say that because all my info, particularly from some great coco guru's here, say that they run at most 1.8EC (1.0 EC = 500ppm)... that the plant isn't showing major nute burn is a mystery to me,.... hence my concerns about the TDS readings! That said, the run-off is too far over what the input EC as well; whatever the case, I suspect this is starting to cause a lockout of a micronutrient... What's the base ppm with just the Ca-Mg? CANNA is a coco specific nute line, right? might be that it has all the Ca-Mg in it you'll need as is, IF the coco was well buffered (not pH, but CEC) beforehand....Day 75: So a couple of other leaves are showing some early signs of spotting but its not spreading fast at least.
Gave her 3.5 L of pH 6.14/1850ppm with a R/O of 1L at pH 5.89/2940ppm.
Day 78 was a quiet one, no water and no trim.
Day 79 a few more sick leaves so things are still not well with her. It isn't spreading fast or affecting a lot of leaves though but more than I'd like.
Decided to put 10L of pH 6.10/1600ppm through her to flush out some of the salt buildup ..with no 1ml/L calmag added for the first time in the grow.
After around 5L she started RO.
1L was pH 5.63/3340ppm ... yikes!
2L was pH 5.79/2720ppm ... still yikes!
3L was pH 5.84/2370ppm ... still yikes!
4L was pH 5.89/2150ppm ... still yikes!
5L was pH 5.94/1980ppm ... hmm better than the 1st L of RO I guess.
Had to stop there as I'm out of distilled water.
I'll likely repeat the same process again tomorrow until the ppms are back within a few hundred of what's going in.
Overall she's not exactly in bad shape, but having come this far, I don't want to mess up the home stretch...
She's getting frostier and stickier each day and the main cola is getting a little girthier...

3300 ppm run off ???
Wow,that's quite high...i think ?
from a distance looking pretty damn fine plenty of tops n getting hairy
keep er lit
mmm, personally, me thinkz she needz a few dozen more bud sitez, but... ppp
