Hi Katoikos
Just a thought,do you allow the plants soil to dry out before the next watering? I've suffered from a nutrient lock out with all mix because of not letting soil chance to dry...could be?

PLease help!!!



I am in the mid stages of 12/12 in my white Russian indoor grow, as can be seen in the indoor grow diaries.
Unfortunately one of the ladies seems to be showing symptoms of a problem. I have looked through to info on here and to me it looks similar to calcium or magnesium deff.
Can anyone offer some insight? This is becoming quite a worry. It does not appear to be infecting the other plants so I hope it is not an infestation.

Comments most appreciated.

many thanks sickehand. I did suspect cal mag problems!   I have ordered TNC calmag nutes, but I have a question..
will add too the watering at 2ml per litre, as recommended,but it says can be foliar fed also.
Is this wise at about 40 days into flowering? If I do spray them, should I avoid the buds? And should I Spray when lights are on of off?

Well, due to being a bit panicked, I have proceeded to give the plant in question a 3x pot flush, thought it would be a safe bet, and not to much harm, even if not required and a good feed of bloom and calmag, time will tell if it was the right thing to do.
When I get my sprayer, I will start a 1/2 strength calmag foliar fed and play it by ear...

Hi abbmacher,
First of all I agree with sickle on this being a Cal-Mag problem.

Now a general guideline for foliar application of Calcium fertilizers is that they shouldn't be applied later than a month prior to harvest. This puts you in a bit of dilemma as root application of Cal-Mag is not as quick and effective as its foliar application.

If the problem is extensive and needs immediate attention then by all means go for the spraying. Otherwise, considering harvest is not far and mild Cal-Mag problems are more of a nuisance than crop-killers, I would try to contain the problem until harvest using root feeding of Cal-Mag and avoid the risks involved in spraying flowering plants.

Just my 2 cents

Cheers

Many thanks for the help guys. The previous plants have come down. the one above seemed to be stunted and stopped growth. Still, I got about 2oz off her. The other sister was chopped a few days ago and I think in the region of 3-4oz of her.
The problem I have now is of a different kind. the clones seem to be showing signs of a problem.
Please take a look below and let me know any thoughts.

From the Cervantes table, this could be one of a few late-stage deficiencies - mayber nitrogen, but looks a bit more like a lack of  a micro nutrient such as magnesium, sulphur or zinc.

Try a complete veg nutrient that contains trace elements.

ive heard from several people in my area that sprayng nutrients is not even close on effectivnes when compared to root fedding ,would this happen due to high temperatues in my living area so the leafs should be let quiet for transpiration? or is this rule of thumb all around the wolrd regardless of general temperature on the area?

by the way thanks a lot for the post snoopy ... speachless to say how much helpfull all that info is for noobs :D
