Hey guys, a big thanks in advance for those who help and have helped before. These poor ladies had just started to recover from toxcity when this showed up... I though it was a P def so I added a very dilute solution of Kool Bloom last night. Any ideas? I cant afford to sacrafice anymore yeild!!!

same thing happened to my skush i think it was nute burn to much p i think
i used earth juice 0-3-1 it burned my shit twice 2 diff strains strong stuff have to use lightly

Yes it does look like something has reached toxic levels, in order to give a more informative answer to your question let me ask you something:

• What type of system are you growing in?
• What are the PH and PPM’s of your solution?
• What brand of nutrients do you use?
• What is the nutrient ratio that you use?
• What type of additives do you use if any? (besides Kool Bloom)
• How often do you flush?
• How close is your lights to the plants?
• Do you use a Ozone Generator?

In order to give informative information and not to be making blind guess about your problems in the dark we need the details of your environment and system workings.

OK... Im growing in a 3x3 ebb & flow using individual containers with Hydrokorrals. The PH is at a constant 6.1 and PPM@ 900. I use Floranova, Floralicious, Ruby Fulvic, Hydroguard, Cal-Mag Max...and I think thats it. After the nutes are mixed Im not sure what the NPK values would be. I flush every other res change unless there is a problem. Needless to say, I've been doing alot of flushing (using clearex). My light is 13inches away from the tops and is aircooled VERY well. No o3, I use a carbon filter.
I have flushed with clearex, Ph'd Tap, and a week nute solution, respectivly, throughout all last week.
EDIT: Temps are about 72F during lights on and 68 light off...

Nice job, well this is just one stoners opinion so you can take this with a grain of salt, I’m going to point out what I would call “red zones” of your system, and it should be noted that I have never grown in a “ebb & flow” system before but symptoms are symptoms to me so let’s get started.

Looks like you might have a little nut-burn but not enough to cause that much damage imp, but I would make sure that I am putting the right amount ratio that the label says. It looks like most of the damage is concentrated in the upper level of the plants, this will eliminate a lot of deficiency and or toxic symptoms, seeing that each one effects plants differently, as a rule of thumb here’s the method that I use to tell the difference between deficiency/toxicity, for example, if your lights are two foot or more away from your plants its’ going to be difficult to tell if you have deficiency or toxicity because there’s not enough light intensity being placed on your plants unless it’s totally whacked-out, the more intense the light is the more your plants will show you the problems and being able to read those problems could mean life or death for your plants, here’s the gauge that I use, if your light is very intense and your plants turn a “dark green” then it’s most likely a deficiency, let me illustrates one of the main problems in diagnosing nutrient problems by visual inspection. In the vast majority of cases, nutrient deficiencies can substantially reduce production without showing any clear symptoms. This problem is referred to as "hidden hunger". (By the way, the “dark green” plants means that there is a deficiency in potassium—phosphors) stunted growth is often associated with these symptoms.
While deficiency symptoms are sometimes seen, it is often too late to correct the problem, especially with short term crops. Correctly identifying the deficiency symptoms can be difficult if multiple deficiencies occur at the same time. Visual diagnosis of crop growth, if correct can help in future management but is at best a much less efficient way of solving crop production problems.

Now if your plants began to show “rust spots on the leaves or is very brittle and discolored” then in most cases it’s toxicity.” In your case this looks to be right, the very first thing I would do is to stop using all those extra products and just use Floranova and possibly one more bloom additive and that’s it!! Your problem looks to me like you have to much Magnesium (Mg) and that is toxicifing in high amounts and effects the top’s of the plants first that gets the most intense light, your not adding Epsom salts are you? If you do not think that that is it, then in my opinion it defiantly is an overdose of something? To me you are defiantly in the toxic zone!! Cut back on all those additives, if you feel like you need to use any added product pick out only one to mix with your solution and no more, that’s imo, but at this stage of the game it’s all most to late but it’s never to late to learn for the next grow.

Well I hope this helps in some small way bro, good luck with your grow.

I have already come to the conclusion that this harvest will be horrible, I do, however need this crop to pay some bills so i hope I can pull atleast a pound...i hope... Reguardless, clones are already rooting, so the next round will definatly be better.

[flipmastermike]

Awesome post BigToke, Thanks for the usefull info.Your reply to his issue is very helpfull.
BTW IgrowmyOwn. Good luck recovering,I hope you will still be able to pull a nice harvest out of it.

...and if i have to buy one more bag of pre-mature buds im gonna freak out...

manganese toxicity no doubt , flush with 1/4 strength . Looks alittle to far into bloom to correct though . sorry homey

[igrowMy0wn]

Well, just so I dont leave anyone hangin'. They have recovered and are finishing up. I bet yeild will be HALF of what I expected but hey, less weed is better than no weed, eh?
