Odd rust colored spotting starts second week of flower

[Rupert421]

I think we may be onto a temp issue… it makes sense after explained of how high temp will effect the processing of nutes.. but again if I’m not that terrible on temp.. what the heck is going on!?!?!? Hahaha!

Here is a zoomed in picture of the earlier posted..

could be high nutrient levels, causing a calcium-type problem as well. What ppm are you feeding the plant? Even though it's DWC, I would bring PH up so the plant can uptake calcium and magnesium better.

Hey IC94,
Definitely hear you on high nuit levels, as I do agree my foliage is quite dark. So enlighten me on ppm.. have never tested for, and always tried to keep my PH spot on for both DWC (5.8ph) and soil (6.8ph).. but have I guess always had decent luck if I’ve never ran into this before..

Sometimes a low pH can cause a tox or nutrient buildup because the plant can't uptake calcium or magnesium as good, which appears as a deficiency but is actually a pH problem. Most times, the best way to solve the problem is to correct it rather than add nutrients. thinking it's a deficiency, just as when nutrient levels are too high, the plant will not uptake it, therefore showing a deficiency/ burn. Your case could be something different, though but I'm pretty sure it has something to do with PH being off or a high level of nutrients.

Ok I’m on the same wave length brother.. so for hydro I’m usually looking for 5.8ph… what would you suggest? And kick back nuits to half for now maybe?? Until feeding signs show?

GNick,
Man, pictures look extremely similar to what I have.. looks like I’ll be tossing all netting, fans and sanitizing the crap out of my tents after harvest.. I think you may be on the right track my friend… unfortunately.

not only strains but sometime even phenotype within the same strains don't react the same to environnemental conditions. but at 80 your fine, below 96 cannabis seem to do it pretty well from my experience

I agree on the manganese, though, there is a lot going on here. Critters, heat. Some iron issues. I would just try to limp it through to harvest, and try to rethink some stuff, try to dial in that environment a bit better.

just a friendly reminder… this is only happening a couple weeks into flower.. maybe just timing??

I’m not much of a dwc head, though I’m fixing to take the automated plunge, I’m just trying to read you leaf health, but, as far as the nutrient science end of the method, I would be wrong to say one way or the other. I know the plant waaaay better than that particular style. It totally could be timing though. When you made the switch, and whether the plant was there yet. Or vice versa. This is just me going through some of the logic tho. I really hope you are able to get it done homie! I’m gonna hang out, and try to learn too.

 

[Rupert421]

Totally my man, the thing is this happens with my soil set up as well.. not just the DWC.. and use a different nutrient solution compared to the DWC… so in a way I do lean towards the viral issue but is definitely a tough one to peg. On the bright side I’m glad I’m throwing everyone else for a loop rather than making a common overlooked mistake.. thanks again everyone!!

 

[Rupert421]

DWC is a totally different beast.. in my eyes a bit easier than soil as long as PH and whatnot are spot on.. anyone who wants to try it I highly suggest.. not to mention the end result!

not saying it is but worth checking into it

Any chance we are looking at toxicity from the trifecta crop control? You mentioned you apply this routinely.

Actually I read the product formula. It has nothing in it but plant oils. Pretty useless for the label claims. But the uniformity on the all the plants made me think trifecta.

It’s ALWAYS worth checking into these days, between that and hlvd……..youre a stalwart against this stuff. I say always bring it up as much as possible these days, as growers, the odds are stacking against us with that crap. Cheers.

 

[Rupert421]

Zill,
This is a possibility that would have to take into consideration… the don’t spray after week 2 of flower to minimize after taste of residual spray. Definitely an odd situation.. I can take some fresh pictures later this evening once sun rise comes for the ladies .

 

[Rupert421]

Any suggestions on crop control sprays?? What are you guys using?? I usually get caught in my old ways and don’t like change..
