Hi all, first time poster / noob grower here. I've done a deep dive on the web to try identifying my issue without posting yet another "my plant is yellow HELP" thread, but I'm at a loss, so... Here goes nothing. Vital info:
1. Growing from seed, outdoors in pots. Strain is BOGGLEGUM.
2. I have 2 plants, 4ish weeks into flowering. (I didn't keep a strict journal, which was a mistake.)
3. Plants are about 3 ft and 4 ft, the 4-footer is the one with the major issues, but now the 3-footer is turning pale and its lower leaves are yellowing as well.
4. Potted in 5 gallon grow bags. (Next time I'll go bigger.)
5. Soil is a mix of Ocean Forest and Recipe 420.
6. I water once a day, in the morning. Sometimes a second, smaller watering in the afternoon if temps are extreme (here in SoCal we've hit high 90s a few times this summer). I was paranoid about overwatering but I'm pretty sure I'm not -- the soil is very dry by the time I water and the few times I've let them go longer just to be sure, they've started wilting quite obviously.
7. I've tested my tap water pH a few times now and it always comes out around 6.5. I've added nutes and tested again, it's around the same. Since I thought pH might be an issue, I did a few waterings using pH down to get the pH closer to 5.5-6. Didn't seem to make a difference.
8. I used DynaGro GROW fert during veg and switched to their BLOOM for flower. I add the recommended dosage of a 1/4 TSP per gallon. Initially I was doing every other watering but as the leaves began yellowing I switched to every watering, thinking it was a nute deficiency. Hasn't done anything, from what I can tell.
9. No foliar spray. Honestly, I don't quite understand the concept.
15. I have the usual SoCal insects, nothing looks invasive or damaging, from what I can tell. Have used NEEM spray on leaves a couple of times after I noticed nibbles on the fan leaves. Worked well.
16. This is my first grow, so there's a lot I don't know. Very willing to soak up knowledge!
OK, so with the facts out of the way, basically my 4-foot plant started yellowing from the bottom a couple of weeks back, and it's gotten progressively worse, with more leaves turning pale green, then yellow, and finally withering to a brown, wispy husky. Also, the stems on the yellow leaves turn PURPLE, which you can see in the photos. (In general, this plant has had a pale look throughout flowering, which the web tells me is no good.)
The second plant (3-footer) has looked much more green and robust from the jump, but is now getting the same pale look toward the bottom and leaves are yellowing.
Again, I think I'm 4 weeks into flower, which seems too early to be seeing this kind of yellowing. All my research point to an N deficiency, but adding the DynaGro GROW nutes back in the mix to boost N levels hasn't done anything.
The other thing that occurred to me is that I should've gone with bigger pots, and maybe there are root issues, but it's way too late to re-pot now so I'm wondering what I can do to hold on through the next few weeks and manage a decent harvest.
Anyway, PICS are attached, would love your input. Thanks for reading and for your help!
