Hey guys I have three 007 plants 26 days old that are under a 400watt MH 10 inches away. Room temps are 75f 60% humidity always as they are automated. Res temp is close to 75 also I realize it needs to be lowered a bit but I dont believe this is the cause of my problems. My ph is at 6.2 and ppm is at 450-500 today. Starting pH was 5.8. I started plants off at 250ppm using 1/2 stength nute recipe on bottle, I'm using 3 part Diablo Nutrients(Grow 6-0-3 Bloom 0-4-5 and micro 4-0-12). I then spoke with others and was told 250 was too low for them and bumped up to 450 by adding grow (6-0-3) only, I was told that the plants mainly need nitrogen right now...




On the lower 3 leaf sets rust spots first appeared near tips and then eventually spread over whole leaf and now leaf is dry,brittle and curled. It starting to spread up the plant by the looks of things too. Wondering what the cause of this is and what I can do to fix it. Thanks







Here are some older pics before the leaves turned into what they look like above:

Edit: ok what do I know about hydro lol.

I'll stick to soil....

your ppms are way to high you need to flush out your system and lower it

what nutes are you using and how much?

hey radium im looking for some good nute burn pics for my guide do you mind me using your pics? your name will be as the contrbutor of the pictures

how much nutes are you using per gallon of water on that?

i would lower your nutes around 300 for now

6.2 ph would definatly not do that much damage to the plant
its the nutrients that is doing that

how often are you checking your ph?

Stitch ahahah of couse you can use the pics! Im not sure if i want my name by it though lol. I am using Diablo 3 Part Nutrients. 6-0-3 Grow 4-0-12 Micro 0-4-5 Bloom. ppm is only at 450-500 Dr.Longbottom who is well experienced told me to raise it to that, also week one on the bottle recommends 450 ppm... I dont think the ppm is that high and shouldn't be burning them that much either...... all the plants are quite big and the roots are still vigourusly growing...I check my ph and ppm daily also. As you can see from the other pics they are all quite big and 450 ppm shouldnt be burning them...

radium are you a member at pg?

add some cal mag or some epsom salt you have a hardcore magniesim diffiency...

Ignore MyNameStitch at your peril, she's like the Mayo clinic of Pot plants. Not knocking your other folks advice, but unless thier growing the exact same strain under the exact same conditions, thier advice may have caused more harm than good.

Stitch says it's nute burn, then I'm willing to bet its nute burn.

Its not nute burn.

I told you my opinion already , but here it is again, the reason for your probs imo is:

I started plants off at 250ppm using 1/2 stength nute recipe on bottle, I'm using 3 part Diablo Nutrients(Grow 6-0-3 Bloom 0-4-5 and micro 4-0-12). I then spoke with others and was told 250 was too low for them and bumped up to 450 by adding grow (6-0-3) only, I was told that the plants mainly need nitrogen right now...

First you used half strength, then, instead of upping the nutes the way they are supposed to be used (using more nutes, not just one part), you only used one part...

IMO stick to the recommended formulas, don't use half strength, don't do funny stuff like trying to formulate your own mix without the nessecary background information.

In hydro we do not just target each defiency for itself, we try to use good nutes formulas that will not lack this or that.. also, do not wait until a def manifests itself and the plants stall and get eventually sick, that achieved by using a mix thats known to work. When nutes mixed and sold for our favourite plant, just use it the way it was intended to

There is still this myth out there that DWC can't handle full strength nutes... its not true.

Hydro works fast, especially DWC, that means things are going really good or really bad very fast...

So this is my problem I have some people telling me its nuteburn others are telling me it isnt. So what exactly is the problem then mace_ecam? You explained what happened but failed to explain what the problem is....You said the plants were hungry and thats what the rust spots were.. I bumped the ppm up and the leaves got worse..

CAN SOMEONE PLEASE CLEAR THIS ISSUE UP AS IT IS MAKING IT WORSE ON ME WHEN PEOPLE ARE TELLING ME COMPLETE OPPOSITE THINGS....
