Pan x mal genetic make up is a heavy feeder. That is one consideration.

Another consideration may be is an imbalance in pH, ratios of nutes, cal levels etc.

My $0.02 is to send that other batch of soil in for analysis, get that batch corrected for your next round.

Good luck, take it easy man!

Although not highly reliable, checking the runoff with an EC and PH meter next time you water might at least tell you if you are too hot or way out of line on PH. In looking at your newest pics, they still look hungry to me. Only other suggestion - and I'm saying this only because I just went through it - is some type of pest. I had russett mites two weeks ago and was sure I was just chasing a repotting/nutrient issue. A fellow member pointed it out to me based on my pics. If your soil EC/PH are not way out of wack, scope your plants for pests.

Well that's a strong possibility because I've been dealing with russets for a while now, I've been doing spinosad sprayings 2 weeks and neemoil soil drenches every 4 weeks. I haven't been able to see any with my scope though, but I know they're small. When I first noticed the infestation, there was a brownish dust on the plants and tips of the leaves after a foliar spray. I'd look under the scope and see the little larvae wriggling around, but I haven't seen anything like that for a while, and I've been scoping them out pretty well. I mean, I know they're around, but I would figure that if they could do damage that bad I'd see some sign of them, especially since I'm looking, and don't see a "infestation". I've been told to scope leaves just above and below damaged ones, so I look at leaves from all over the plant just to be safe, and I haven't seen even one of then let alone an infestation. SO yeah not sure what conclusion to draw from that. I've had them, but they seemed treated.

How can I use the run-off's pH number to determine if it's too hot? Will it be very high or low? I have a pH soil probe and it says it's at 7, which is what the soil analysis said as well ( well it said 7.2 ).

Do you know if the Malawi feeds heavier than the Panama? Because the Malawi x Panama #3 phenotype I have that is the yellowest, is also the most malawi-dominant from what I can tell. So that would be more evidence in the under-fed column.

The numbers from your ph probe are good for soil, assuming your probe is accurate. Checking the runoff for EC might let you know if you are hot if you get some crazy high numbers, say 2.0 for example in the runoff.

I'm about to flip my girls to flower on Saturday after several rounds with No-Pest Strips during lights/fans off. I've yet to see a live russet either but I will be one paranoid grower until I trim the last bud from this run.

Oh yeah I forgot to mention I hung a couple No-Pest Strips up as well for a small time, about 2 weeks or so. I didn't think about doing it at lights off, I was like, 'How can I do this with fans off?' and just didn't sleep in that room or let my pets in there for a couple weeks. That stuff put a weird smell in the air, so I'm trying to avoid using them again, especially during flower. But with the spinosad + neem I haven't seen a sight of them for months now.

Hmm so is EC different from pH then? I've always been told they're the same, or at least you can use a pH meter instead of an EC.

Is an EC of 2 really that high in organic soil? thats only 1000ppm (anything over 1000 and a red flag goes up for me in soilless with bottled nutes). But I notice that in my organic mixes and EWC it jumps up to 3000-4000. Makes me think that most of those ppms arent all just elements in their soluble/available form, and just other organic elements compounds etc.

[starke]

PaulieWaulie is right. EC 2.0 might not be out of line in soil. I grow hydro now so tend to view high EC as a bad thing.

Yeah I think I tested with my TDS meter one time the runoff from it and it was up in the 10k range, but I don't really trust my memory.

What I notice is that since I switched from Happy Frog soil, when I water with plain water, the run-off always comes out deeply colored amber/brown like there's a lot of stuff in it, whereas when I ran plain water through Happy Frog it would come out almost clear sometimes.

Truely its hard to say from across a screen. I looked harder at the second pictures, only a shorter plant on the bottom right of the one picture, a wider leaf variety shows a very tiny bit of Nitrogen curl, on only 2 leaves.

Neem is mostly N (5-1-2 or 5-1-3), and if I remember right the bio live is what 5-4-2. Both are leaning heavy towards nitrogen, especially for flowering. So I would assume if it was over fertilized, you would see a lot of Nitrogen curl/claw. Have a friend who uses Miracle Grow, and I have been to his garden when he over does it... lol.. some serious Nitrogen curl.

The plants are also pretty large for their pot size. I am not saying they are overgrown, but I would assume even with a really rich soil, a plant that size in that size pot would need some regular feeding to stay healthy.

Your logic on the little plant doing better seems pretty sound.

Crush some of the seabird pellets up. Thin layer of worm castings, thin layer of seabird, cover it up with a thin layer of compost. If you have some liquid kelp, or seaweed powder to. Kelp is so broad spectrum, really good at greening a plant up.

Test it on a single plant, and observe. Worst case you make one plant go downhill further, and gain some experience. Best case, the plant improves and you gain some experience.

Canna plants really devour nutrients. Especially big plants. If you have a good amount of some really nutrient rich soil, and you grow small plants very little veg time, and quickly flower them, like SOG style, you can get away with not feeding much or at all. Big plants in small amounts of soil.... they need to be fed on a regular basis imo. More soil, more plants, less veg time, much more efficient, and much easier.

Cool varieties, and I think your soil mix will be dialed if you keep at it. Can be tricky with multiple phenos, varieties, one is Mag hungry, one is N hungry, one is a light feeder, one is a beast.

Hang in there,
