Cant figure this out

[dopeyG]

I've been trying to figure out whats going wrong here for about a week now. it doesnt seem to be getting any better. i've been watering with just water for the last, i dont know how long. What u think??

 

[indawindica]

you have never given any nutes to the plant?

 

[dopeyG]

i am giving it a veg nut and just started using mg and calcium booster i think 2 weeks ago now

 

[ismokealotofpot]

Try calmag give it nitrogen but scale it down a little bit It looks slightly burned. calmag should clear it up i think you did good by giving it just water. when you get real dark leaves its a sign of over feeding with nitrogen. over all it looks good.

 

[ismokealotofpot]

yah you need calcium for it to absorb magnesium

 

[dopeyG]

do u think i should use it to mix a foliar spray or mix it in with nutes? or both?

 

[ismokealotofpot]

Don't foliar spray just mix it with the nutes. one teaspoon every watering see if it clears up. dont do a bunch of things at once you can love a plant to death.

 

[dopeyG]

alright, i'll give it a try. one teaspoon?? that seems like alot. It says on the label something like 1\2 tsp/4L when using jungle green, which is the veg nutes im using. Should i skip this feed of those nutes this week??

 

[ismokealotofpot]

if its cal mag plus it should say one teaspoon per gal or for accelerated two teaspoons make sure you shake it up good. cut the veg nutes in half for now

 

[dopeyG]

it doesnt say anything about using that much. It doesnt say anything about using it alone at all actually. I will cut the nutes in half tho and give some extra mg and calcium. Its not calcium and mg plus, its called cal pow. Im sure its pretty much the same just made by the hydro store here. but maybe could be a little concentrated

Pic number 1 looks to be on the verge of nute burn...possibly a calcium issue. But that looks like older growth in the pic a early cal def signs usually show up in newer growth....

Pic number 2 looks alot like Thrip/leaf miner damage...

 

[dopeyG]

well, as the problem progresses i am noticing now that it is only in the more mature leaves. They start out with what look almost like to be tiny tiny yellow spots and the edges of the leaves are like a coppery brown color. Then the leaf starts to turn yellow and the coppery brown color ends up being dead brown dry leaf

the first pic looks like a problem i had with a really high ph and it spread super quickly, so check your ph maybe but the second pic does not so im not completley sure.

what is your water PH?

 

[mikerob]

How big is your pot that happened to implants was root bound

why do you say rootbound? i myself have never had that problem happen but i havent heard of it looking like this?

 

[dopeyG]

i doubt they are root bound, they are in 5 gal pails. as for ph, i have no idea. A ph tester is one of the things I havnt invested in yet. Would love to have one

 

[mikerob]

You can get one at your local fish supply or pet store!

 

[mikerob]

TThey are like $20.00

 

[dopeyG]

Are they as good as the ones you get in a hydro store?? What about those ph test sticks?? do those work well?

ya dude id guess your ph is about 7.6-7.8, if this engulfs more than half of the leaf its presemnt on, it will spread to the rest of the plant over night. you need a ph tester and some PH down or dolomite lime to get it under control. let me know if this fixes the problem when you try it.
