Guide to Nutrient Deficiency or Toxicity

http://www.planetnatural.com/site/earth-juice-microblast.html this stuff? that has 0-0-0 NPK. what are you using? yes theres deficiencies, it needs N and P, as well as micro nutes. but its also tiny. id go 1/2 strength MAX on anything id use.

hows the drainage in those little cups? as long as drainage is good, and pH is right, then yea add some nutes

yes thats my micro nutes, i use this along with the entire earth juice lineup
and a guano, seabird, wormcasting pre-mixed powder and i compost tea for feeding.
i was told it was nute burn before anyone else/you could get back to me, so i flushed with a gallon and a half for all 22 half full solo cups last night. ph'd at 6.5 incase ph was an issue, i checked my runoff and it was 6.8-6.9ish...
and the drainage is pretty good only in pro-mix organic, 6 holes in the bottome 1 hole in each side(4 total) and i poked holes in the soil(3)
its been about 18 hours and its definetly gotten worse but it may have leveled off i cant quite tell..........
im not sure what to do im think i should transplant into larger containers and MAYBE foliar mist some Thrive alive B1 (organic b supplement and derived from sea kelp)....
 
This is the only plant in my grow that doesn't have spots, dots, curling, burning, tacoing, or yellowing, it's a white widow.

Here's more White Widow and White Russian with bad yellowing. Botanicare claims you can use just 1-5-4 for flowering, I'd hate to see what that looks like.

I'm growing in coco, and using reverse osmosis. Both these conditions call for extra calcium, so I use 5ml per gallon of CalMag and use Botanicare's CNS line made specifically for coco substrate, yet I still get this with White Russian.
.DSC01839.jpgCalcium deficiency right?
And then there's this going on, whatever it is. I wish I knew.

could be calcium, magnesium, phosphorus, zinc deficiencies, hard to tell really, either way, its not nute burn so up all the nutes a bit.

i get some funky shit here and there too, a leaf with some spots, another with curling, etc etc, as long as theres no nute burn, then you can add more nutes (some of each) and it will work itself out. i barely try to figure out what exactly is missing, i just get a general idea of what couple causes it could be, and treat for them all.

1-5-4 for flowering? eh... maybe... i try to stick to something more like 3-7-7, and i overload mine with micro nutes during flower. i try to never have deficiencies during flowering, id rather risk a little nute burn then a underfeeding. i like feeding a healthy amount of Nitrogen too, i dont like seeing yellowing on my fan leaves even in flower.

my main issue right now is my college classes just started up again so i cant focus on my babies all day like i used too, and its cold here now and im having a hell of a time taking clones (took 20, and maybe 1/2 died due to mold, just too damn cold and wet).

nute burn is the ONLY thing that appears on the EDGES of the leaves, starting with the tips, then up the serrated side, it looks brown, and dry to the touch, even crispy like its burnt. unless thats whats going on, then its NOT nute burn.
keep in mind, you can be burning with one element (say nitrogen) and underfeeding with another (like potassium). thats when the charts and everything else really help.

Yeah, the plants seem to have the dame rusty speckles. When I started this grow, I was confident I would be able to identify and treat problems, but that's not so. I'll be content as long as I harvest at least a 1/2 gram per watt of good medicine. Here's some more pictures of problems, anyone is welcome to chime in if they have a clue.
DSC01908.jpgRust colored dots. This White Russian stays green, hasn't ever yellowed.
DSC01915.jpgYellow leaves with light green veins. Her fingers look arthritic, she needs medical marijuana, she's a cripple.
DSC01920.jpgCurly, burnt tips, and it looks like some diarrhea splashed on her lime green leaves. This is not some good shit.
DSC01935.jpgAnd the claw, which pops up on plants that also have yellowing fans, nitrogen toxicity, and deficiency symptoms on one plant, WTF?
 
Hey man heres an update, its been 5 days since transplanting my ladies, ive foliar sprayed them once with thrive alive(kelp and b vitamins)
They looked like they came back and have started new growth, they look quite low on nitrogen since the flush/transplant and are starting to purple slightly at the tips(Phosphorus defic) so i decided to try nutes again today, i didnt do a compost tea like last time, i just mixed nutes into 1 gallon jugs, i fed 1/6 strength grow(2-1-1), 1/4 strength bloom(0-5-3), and 1/4 strength catalyst(.03-.01-.1, aids in vegitation and budding, ej website says to use it whenever using grow or bloom....)
Here are some pics since the transplant, i took these right after water with 2 gallons of nute solution at the previous mixture

View attachment 2144322 Any idea why the cupping i thought it was from underwatering after the transplantso last night i gave an extra gallon of water to the ladies and a few perked up, am i right for thinking they need more water to fix the cupping?
View attachment 2144323 heres a random pic of the worst one
View attachment 2144324 heres a pic showing off signs of N deficency i think
View attachment 2144325 And this is just a pic of them in there new homes

If you could give me any tips, or advice please help! this strain is being a bitch in its early vegging!!!!
What deficencys do you see, any abundacies?
 
I'm growing in a RDWC (recycling deep water culture) I have rust spots that turn brown and than dry up. I've tryed flushing,lowering my nutrients,changed PH ratio, and still can't solve the problem,don't know what else to try,any other suggestions? :joint:

where are the brown spots? unless the death is on the edge of the leaf (signifying nute burn), then your spots are either bugs or UNDER feeding your plants. and flushing, lowering nutes will never help, in fact it will get worse.

if your in soil, staying at 6.8 is the most important thing. 5.8 for hydro (and your RDWC setup). never veer from this. ever.


post up some pics so we can see whats going on.
 
This is my first grow Im using a DWC system with GH 3 part recently switched to the Lucas formula its not too bad just yet but wanna catch it before it gets worse. How should I be mixing my nutes (calculated for 3 gallons) to fix this problem that seems to be a Potassium deficiency?mj2.jpgmj3.jpgmj4.jpgmj1.jpg

up the micro nutes. check your bottles of nutrients and see which has sulfur and use more of it.

i stick to the bottles from petstores for fish tanks, tropical plants, 0-0-0 NPK, 15+ micro nutes, usually 6 bucks. been using that for years as an additive and its rare for me to have anything wierd going on
