(Edit: TL/DR: please look at the pics and tell me if you think it's nutrient deficiency/surplus/or bugs, because I'm confused)
Hi all, I've been trying forever to figure out what issues my plants are having, but everything I look at online looks exactly the same. I can't tell if it's a nutrient deficiency, surplus, or bugs. Could you tell me if any of these are obvious to you? There are lots of little problems that I would like to start to be able to recognize and address on my own, but I'm pretty clueless right now.
First off:
Indoor soil grow (Pro Mix Mycorrhizae), 600W HPS light for 9 plants, LED grow light for 3 addt'l plants, Temp 75-80F, Humidity 30%-40%, 4th week of flower on 12/12 lighting (vegged for probably 2.5 months). Growing 4 different strains: Northern Lights, Girl Scout Cookies, Pineapple Express and ChemDawg. All are clones.
Water when soil is dry a couple inches down ( usually every 2-3 days), and for the first 3 weeks of flower I gave nutrients every other watering ( so 1-2 times per week). Using Botanicare BLOOM Nutrient (1-4-5) along with Cal-Mag and Liquid Karma supplements. 5 mL each of the Cal-Mag and Liquid Karma, and then reduce the BLOOM by 20% to 15mL because using supplements. All of those are per gallon of water.
Since I started noticing problems with the leaves (yellowing, brown stripes, burnt tips, etc) I haven't given nutrients at all for a week, have just been watering regularly when needed. I thought maybe I was overfeeding. If anything though, the problems have gotten worse since I stopped giving nutrients.
The only thing I am unsure of is pH. I'm using well water (filtered, but not reverse-osmosis), and when I've tested with capsules and a probe, it has been 6.5-7. I don't trust the probe though, it never moves from 7 lol. I've ordered a digital pH meter, but it hasn't arrived yet. When I've tested the runoff water it has come out at 7, but I just don't trust that the pH meter is accurate. So, that's an unknown right now.
Please check out the following pics and let me know if anything jumps out at you as a problem you recognize.
Pic0 - just a shot of the grow tent.
Pic1 - shot of the ladies with the lights off
Pic2-4 - These are all of the same plant (Girl Scout Cookies). It is in the middle back underneath the HPS light. I cannot figure out what the brown spots and yellowing leaves are indicative of. It's only on the newer growth, and the brown spots are all extremely regular in pattern. I haven't seen anything that looks exactly like it online.
Pic6&7 - Are of the same plant (Pineapple Express) under the LED light. There are tiny mottled spots. I don't know if it's some kind of LED light burn? It's on random leaves though, and it doesn't seem like all the plants under the light have that issue.
Pic9&10 - The same leaf, from one of the plants under the LED light (not sure which plant). The white spots look shiny, almost like snail slime, and the tiny black dots are also shiny. My thought is bugs, but I've spent probably an hour looking at the leaves, under the leaves, in the dirt, under 60x magnification, and I see absolutely no bugs/no movement of anything at all from what I can tell.
Pic12 - This is a pic of dead leaf, just wondering if those white spots are normal for a dead/decaying leaf, or if it's a sign of mold or something. Some leaves like this are still attached to the bottom of some plants, I pull them off when I find them. Not sure if they're just dying naturally as the plant ages.
Any help with anything you recognize would be greatly appreciated, thank you!!
