help my plants are dying... high quality pics.

[TheXFactor]

hey guys, ive been posting on mulitple forums and still not a single person knows whats going on in the tent here...

heres the story and details...

400wMH 14-24inches, in a homebox tent. 18/6

in happy frog soil. many different brands of fertilizer, all high grade stuff..

i am using R/o water, and i add 1 tsp/calmag/gallon

i adjust ph to 6.5-6.3 as it goes in..

when i first recognized this problem about a month ago, i have been trying to fix it ever since, at first i thought it was lockouut/nuteburn...

Then i thought it was a cal mag deficiency, now im wondering if there is too much calcium/mag.... it has not signs of nute burn, and actually responded pretty well to the post flush feed, but im afraid to keep giving them nutes and end up giving them too much.

ive run through every pic on the web of phosphorus def, potass. def., mag, cal... low ph, high ph... nothing.

maybe someone here can atleast ask some questions, in the past no one even asks me questions.............. how am i sussposed to get help when 60ppl look at my thread over 3 days and no one responds, even after bumping it 2wice...

Clearly nute burn, my guess is from the "many different brands of fertilizer". Even if it is "all high grade stuff", you can still give too much. Do you know how much of each different brand of fertilizer you have been giving and at what ratios?

i have some chemical, and some organic, as im in the mode of swtiching to all foxfarm products, but the organics i would feed at full strength of recommended dose... as for the chemical nute, i feed at 1/4-1/2strength as recommended... every 1-3 feeding i water with plain r/o water w/ 1 tsp of cal mag.

heres the brands.. davids grow, which is a simply hydro nute that comes in a grow-bloom-base, grow 7-0-0, bloom 0-4-7 or 0-7-4, and the base has all micronutes and trace elements...

I have biobizz bloom(great stuff, but not quite foxfarm good, foxfarm has a fert with both organic and chemical but offer multiple kinds of phosphorus. and botanicare pure blend grow(which i was told is good, but salty)

i go lite with those hydro nutes b/c, well they are for hydro but they are the perfect form of usable nutrients when u need them 'now'

as i go forward i will be using only foxfarm products.. happyfrog plus their own nutes, on their schedual....

but as i said, i originally thought it was nute burn, but it looks a lot like the pics of radiation damage from that problem solving link with the brown yellow rust spots, but the leaves all curl up once they're dead... I am almost positive it is deficiency of some kind because when i added nutes to the ones i flushed they responed well initially but couldnt hold its vigor.

maybe it is burn, but u know that burn mark u get on the very very tip of the leaf, these leafs dont have that, which tells me right away its not nute burn, but i might be wrong.

i go very lite on the nutes and that why i speculate its deficiency, but the reason i doubt its a deficency is because it is in happy frog which has ALOT of stuff in it to keep ur plants going for a while... which then leads to salt build up/ lockout, but i flushed 2 of the plants really well 3 weeks ago, and they all still have the same symptoms.

i need these to come around...

what if i watered half with just r/o water w/ 1tsp calmg/gln

and the other half with full strength nutes?

What could i conclude if i still see new growth uglify. on both sides of the variable.

Have you foliar fed them or spayed any water or mister on them ? I got a buddy that just foliar fed some and he thought everyday was okay but after 3or4 days the started to look like that and then got worse.

If not I would just give them all R/O water and no calmag either untill you see a difference.

Oh are they too wet ? My bro has been fighting root rot and that is the look on the leaves before they start turning yellow. You may want to dry them out.

Well hopefully one of the resident pros can back me up on this, but I am 99.9% sure what you have there is bad nute burn. I have a DWC that I was feeding too hard and the leaves started to look exactly like that, dry, rusted looking, and crispy with the edges curling up. I lowered my PPMs and the problem went away. The fact that you are feeding all those different kinds of ferts also leads to this conclusion.

Compare this picture: http://www.marijuana-seeds.net/Thanks/nute_burn01.jpg

With your first post of pictures. They look the exact same, and look the exact same as the nute burn I experienced with mine. The other two sets look different from nute burn but I would assume it is burn or lockout of some kind due to over feeding.

You obviously have nute burn on the first set of pics and/or lockout in the rest, and you need to flush with water only for a while until things straighten back out. The third group of pictures you can tell they are being fed too hard if you look at how the tips of the leaves are starting to curl under and the edges are getting crispy. These are the first signs of over feeding.

You should also probably know the PPM of the nute solution you are feeding, as I find that most recommended doses of nutrients on the back of the jug are way too high. When I first started I followed the directions on the jug and ended up with like 2,000 PPM (way too high). Might also want to use nutrients that are for soil and not hydro. I am sure they make nutrients for different applications for a reason.

Good luck! :jointsmile:

i adjust ph to 6.5-6.3 as it goes in..

Yeah but what comes out is important:jointsmile:
