So this plant is app. 9 weeks old and about one week post flip, it's GHSC's Trainwreck. The bottom leaves are showing some serious distress, brown spots and a few small ones have some very serious wilting, the top of the plant seems healthy enough, there might be a VERY slight lightening of the leave's color but it's hard to say.
Its grown in a 5 gallon DWC using floranova nutes supplemented with thrivealive and calmag. It's worth mentioning that I wasn't having any issues whatsoever before the flip. I switched to the FN Bloom the day before the flip and started noticing issues approximately 2 days afterwards. I immediately decided to go back to the FN Grow until the stretch was over, thinking that perhaps I shouldn't be depriving the plant of some extra N until after the stretch (this is my first grow and it never occurred to me to do a little research as to when one should be switching to a bloom formula....), but perhaps this was faulty thinking. It's been quite warm here the past week or so and the room has been around 85f during the day, but I don't see any inward curling of the leaves.
As for the pH and PPM, well, there we run into an issue. I purchased a six in one meter off EBay (those blue ones that you can hang on the wall), and it seems to have kicked the bucket after only a few weeks (I hope there is a warranty on the damn thing), reading a pH of 100+ and PPM of about 50 (calibration doesn't help). Still, near as I can tell with some strips, pH seems to be around 6, and with what limited experience I have using FN nutes, the pH buffer seems to work very well. With that said, I may be running the solution a little hot (~1300) and have been doing so for weeks (back when my meter was properly functioning) with no issue, could this finally be catching up with me?
Lastly, I'm used to growing cacti hydroponically so I'm not at all sure what a normal H2O uptake for a plant this size is, but she is going through about half a gallon of water a day. I water when I see it's low, but this could certainly be causing wild fluctuations in the pH/PPM.
So here are some crappy pictures, don't mind the said soil grown siblings in the background, last time I ever grow in soil.....
The plant really is beastly besides the mentioned problems, I wish I had LST'd a bit. If you can't tell from the pics, the giant fan leaves on the bottom have sort of been tucked under the canopy by some serious knuckling on the branches nodes. Most of the leaves that are showing issues are the ones that are hardly getting any light, is it too late to start yanking some of those off?
Any help would be greatly appreciated!
