Can you start a help thread in the FAQ? You might get overlooked here.
I won't be back on until later tonight.

They will want more info. Soil type etc.
 
As far as I can tell they are close but not right... My soil meter shows 6.2 for one and 6.5 for the other but they both seem to have 'hot' spots and I cant flush any more. So what I did was flush plants with full un ph'd tap water (from well usually 7.1 to 7.2ph here) after that removed a couple inches of soil from top, replenished with fresh soil, added some dolomite lime to the top of it, gave a very light watering to moisten lime. I talked to a commercial grower and he said since the damage was so wide spread it may be better to just cut the plants back since I was all ready at my limit for veg height and allow them to try to heal and regrow and then go to flower. I was in 12/12 only for a couple days so he said I sould be able to reset to veg no problem. I think I will just focus my time on the 4 clones I got and shuffle these guys around and in spring move them outside possibly...
 
Can anyone help me out with this? Started near the bottom of the plant a few hours after I sprayed with green cleaner.
From what I have gone thru this looks like possibly a Cal/Mag deficiency but it could be due to the spray droplets on leaves and being burnt from the light. Water/liquid droplets magnify light. Hard to tell but since you said it happened a couple hrs after spraying my guess would be due to light burn from the spray.
 
Woah!!!! Try just leaving her alone. Water her....just water. The plant is gonna want to survive itll be ok nature will take care of itself just go easy on the nutes!!!!!$
Wasnt nutes, was ph.... pen was out of calibration, pretty much wiped them out... These too are back in veg and will end up outside come spring, going to work on the four clones I have and just let these two do their thing till spring.

Just for the sake of accuracy, there's no such thing as a "Cal/Mag Deficiency".

It's either a calcium deficiency, a magnesium deficiency, or possibly both. In either case, the supplement Cal/Mag may be required since it has BOTH of those elements. It also may help for an iron deficiency since Cal/Mag has iron, too.

If using R/O or distilled water, you should use a Cal-Mag supplement since the R/O & distillation processes strip those minerals out of the water. Usually it's not needed if using tap or well water and, if those deficiencies are present, more often than not it's due to improper PH.

I understood what you were saying 420%. I'm just pointing out that there is no such thing as a "Cal/Mag Deficiency". :Namaste:

Please help whats wrong? Only one plant affected There are 3 Eleven Rose only one of them makes this kind of trouble she is in week 6 of flowering.
It started at the top slowly goes down to the other leafs.
Its an organic grow.
I dont think its nutrient defficiency... maybe to high PH level but actually organic soil should be able to retain balanced ph.
Or Lightburn?? Nutrient Burn?
Lightburn is hard to imagine.... 40cm distance, cooltube 600W HPS and low temps. Daytime 73F and at night 65F

So either Nutrient Burn or to high PH what do you think?

It looks like an iron deficiency but could be Zinc or Manganese and possibly a combination. Are you growing in soil or coco? If coco, what's your PH?

Awesome info thanks! Probably shouldn't post here... but I have 2 plants with complete different issues.

1) Always bottom leaves. Turn anywhere from yellow, brown, rusty. They get CRISPY. Then when bad enough, another one up the plant starts to go. No idea what's up..

2) Leaves all over, new or old. Always the tips. Yellow, then brown. Clawed. Also, a white-ish fade to man leaves. Think this one is OVER kill with nitrogen.. but not sure.

The plant yellowing from the bottom-up is an indication of a Nitrogen deficiency, however, it's very normal for the plant to shed its lower leaves as it matures and if it's just a leaf or two at the bottom, as it appears to be, it's probably fine.

The second pic looks like possible calcium deficiency. What's your medium and water source?

those are all in soil. My girlfriend was using a new sprayer to foiliar feed them she said using 1Fox farms Big Grow, But I have been growing for a while and must of been somewthing in the sprayer cuz in 3 days they all started showing the same symptoms. A few of them are doing better now. Look at this. I think it is some kind of mutation. I have never seen anything like it. I would love to hear your thoughts on it.
