My Super Silver Haze (Picture 1) is in week 3 of flower and she's trying to tell me something, but I can't quite figure out what it is. A handful of leaves are starting to get brown patches (Pictures 2 and 3), and while I have the sneaking suspicion it might be a deficiency, I'd much rather get the opinion of someone who has seen and dealt with this before instead of stressing her out more by trying a dozen different things. Some of the other leaves are just starting to show symptoms as well (Picture 4) so I know it's not a problem that's already fixed itself and is something I need to correct. I thought maybe it was just older fan leaves, but I can see there's some browning on newer growth too (Picture 5). Tersky suggested I show a few photos in more white/nautral light as well, so photos 6 & 7 are taken in natural light, with flash off, and then on ðŸ‘
I only feed her every 3rd watering (and going 3-4 days between each watering), but because I currently don't have access to a PPM meter, it's hard to tell if I've inadvertently gotten too heavy with the nutrients and she's locked-out/running hot. I've seen plenty of stuff online that looks similar, but they all have differing causes - nute buildup, rust, calcium deficiency, heat stress, light stress, etc. My only thought is that I usually try to pH my water to around 6.2, but recently I've seen some soil pH diagrams that say you should try to hit 6.5 in soil. Any idea what my girl might be trying to tell me? Should I just flush her out and see what she does next?
