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.

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.

hello! our guide is very helpful.. but I cant figure out If my plant has a potassium defficiency... 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?
