Calicum deffiency??

[smpaz420]

E-indoor
E-soil
E-specific medium- FFOF with 1/3 pearlite
SCL-Have been using FF ferts big bloom(4tbs) and tiger bloom (7ml)
SCLR-6.7 roughly with my Gh test kit
E-Tap water
E-ph 7.5 going in
E-2 month old plant
E-600 watt HPS about 18 inches from plant
E-80
E-25%
E-12/12
E-6" vortex

This looks like a Calcium def just from pictures i have seen, any help is appreciated! Out of 3 this is the only one showing these symptoms, everything has been done the same with these plants.

Is this plant right under the light? It looks short and bushy and I'm wondering if you have more a heat stress problem than nutes. Putting a bright light close to a plant might cause it to grow short and bushy along with showing heat related leaf tissue death. I wonder if 18 inches on a 600 sodium is too close.

[smpaz420]

part of the bushiness is probably that i flowered under mh for 2 weeks to keep them shorter then switched to hps. here are my other 2 tell me what you think.

[polishpollack]

Those two look great. I have to guess that the spotted plant was the one right under the light. Since you have three, why don't you consider putting the plants in a triangle shaped position, with an opening in the middle. Also raise the light some. Some people say that a good rule to follow concerning lighting and its heat is to put your hand right above the plant and if you can feel the heat from the light on the back of your hand, the light is probably too close and should be moved up some. you could buy a mover but personally I wouldn't want to spend the money for just three plants. So how about raising the light and putting the plants in a triangle shape, then spin the pots around to expose the other side of the plant to more light once or twice a day. That should be fine. Best of luck.

If you are in soil your ph should be 6.2-6.8.....your soil, your nutes, your water, your runoff. Your ph is WAY too high.

[smpaz420]

not from what stinky told me it is not to high, i was told to get it towards 6.8 as she said 6.5 is to low for a soil grow. i have read the flush sticky many times and it contradicts what i was told to do as far as what is a good ph to use. here is my other thread i had where i was told this. http://boards.cannabis.com/plant-problems/165677-browning-around-leaf-viens.html

Certainly not going to argue with you. Best of luck in your grow.

Have a good one.

[smpaz420]

im sorry i wasnt intending to be argumentitive, just trying to confirm which info is correct. both of you know alot more than i, im just confused as to where the ph should be.

Here is a really long read about ph and some good info....definintely worth reading. May help you make your decision about what your next course of action should be.

Good luck.

thank you WH, i meant no disrespect, just trying to clear up my confusion about ph, thanks again.

Soil pH should be 6.6-6.8 ideally.
Soilless should be 6.2-6.6 ideally.
Looks like possible Ca def or lockout due to high pH; a plant right under the light will grow more rapidly and use up available nutes/minerals faster.
When was the date of your last re-pot?

[Weedhound]

Ok...I got the part about the soil.....but what about the water or nute solution you are pouring? Should it or should it not be between 6.2-6.8 or does it not matter as long as the runoff is normal?

Sorry for threadjack sy, just want to clarify something I'm not sure of and it still fits in with your question (I hope.....:D)

[stinkyattic]

To be honest, if pot size is correct and soil type is correct, you can get away with not checking your fert pH (as long as you are using a pot fert, and NOT orchid or azalea food!!! :eek:).
6.2 is WAY too low for soil. 6.6 is the absolute lowest I would ever feed, because you run through your lime SO fast going too acidic, and given the choice, in a peat-based medium, I would just feed with tap water plus fert that usually seems to come out around 6.9 with my city water.

I think that plant needs to be re-potted like, last month, lol.

[smpaz420]

thanks alot you guys, i appreciate the help, and the clarification of ph issues. they have been in these pots for a little over 5 weeks now, is it okay to transplant during flower? i didnt think it was ideal so i try to transplant into the bigger pot and finish it in that one.

[smpaz420]

here is a pic with the container.

[polishpollack]

Personally, I'd transplant to five gallon buckets or bigger.

[Weedhound]

I agree with polish.....it's time for them to get some more room. That may indeed be part of your issue as well.

[smpaz420]

ok i have some 5 gallon buckets i used last time. After i harvested looking at the roots they were not really at the bottom, so i figured i could get away with using a smaller pots. these are 3 gallon in the picture. thanks again for your help.
