Hello! This is my first grow and since I have been using many other people's journals for referance and ideas, I though it might be benificial to someone else if I were to start my own. Or at least as a way to keep a digital record for my own reference. This being my first grow, I welcome any suggestions or comments on my setup, plants, and/or techniques. Afterall, thats what online forums are all about. I have no prior experience with growing, although I have had friends in the past who had small indoor gardens.

Setup:
Grow Area: 3'5" x 4'5" x 10' tall closet. Insulated (was built as a meat locker by the previous owners).
Reflection: SunFilm metallized film (mylar)
Lighting: Sun System 315w LEC (ceramic metal halide) running @ 18/6 for veg.
Grow Medium: Soil (Nectar for the Gods #4 and Fox Farms Ocean Forest w/ ~20-30% pearlite added)
Nutrients: Nectar for the Gods advanced line given @ 1/2 strength.
Temps/Humidity: 75-81 daytime/61-67 night. 50-55% humidity.

Strains: 2 x White Widow @ 2nd week veg
2 x White Cookies (Widow x Girl Scout Cookies) @ 2nd week veg
1 x Purple Kush @ 2nd week veg
1 x Purple Kush @ 1st week veg
2 x Mystery bag seed @ 4th week veg

looking good so far. your ww#2 looks like it could use something. what is your ventilation set up?
 
Growdict, thanks for your reply! I believe the WW2, and also the WC2 to a lesser extent are going through either a magnesium or iron deficiency. Someone also said it might me nitrogen deficiency but I have been feeding regularly and also the soil is nutrient rich, but not too much. I have been using R/O water, but started using ph adjusted tap water today to see if that helps. I have read that R/O strips away all of the minerals in the water and can lead to a number of negative effects. I am on well water out here, and when mixed with my nutrients it results in a Ph of 6.6 which I have been using as is. If I see a Ph issue I will lower to the recommended 6.4. I think 6.6 is going to be fine though.

My ventillation is a 12"x12" closeable vent for fresh air to come in. It also has a Filter filter in the inside to prevent bugs and dust from getting in... It is very dusty in my area.
I will be adding ventillation to the ceiling provably tomorrow. It will be 2 - 14"x10" vents cut directly into the ceiling to vent into the "attic" space above with mesh screening behind to prevent bugs from entering.
It has been cool lately so temps have been holding at 77-80 without any sort of exhaust other that sometime leaving the inner door open. But on hotter days it gets up to 88 in the grow area so heat exhaust will be crucial.

Oh and I forgot to mention; the light distance is at 21" for the larger 2 plants, and 26.5" from the canopy of the 6 smaller ones. I will most likely flower the larger 2 in a few weeks in another area as I am unsure if they are male or female. The other 6 are feminized seeds. Once I know the sex I will either just continue to flower and finish them, or I will put them back with the others if theyvare female.

I have also included pictures of the two with yellowing as well as the largest plant which is showing some minor yellow spotting but its looking great so far.

I am starting to notice some yellowing and minor brown spots/cuts on a few leaves of different plants. Im not sure whats going on but from what Ive been reading Im suspecting either a nitrigen or iron deficiency. i gave a feeding to all of the plants today at half dose and using tap water instead of R/O, which is what Ive been using from the start. The only problem is that it has a much higher Ph. After nutrients are all mixed the ending ph is 6.66. The suggested Ph with the Nectar for the Gods line is 6.4. I tested the runnoff of a few plants and got 6.46 each time. I suspect that once I start using tap water consistantly at this Ph that number will go up. So I ordered some Ph down today (all I currently have is Ph up because with the R/O water, once mixed resulted in a Ph of 5.4-5.6).
It also seems as though growth has slowed dramatically on all plants. This could be due to the cold weather in the last few days. It was down to 56 one night and last night was 61 when I checked in the morning before lights on. It is supposed to warm up in the next few days and be nice and sunny for the forseeable future. There is also some minor purpleing in the center/newest growth of 2 plants (WW#1 & WC#1).

If anyone has any suggestions as to what it could be, please let me know. I might also pick up some CalMag too just in case.

Day 16 of veg under 18/6. I have decided to start flushing with next watering on all plants with Ph 6.5 tap water. I tested the soil Ph today on WW#2(worst one) and WC#2, using soild taken from the top and Ph 7.0 bottled water and came up with a Ph of 6.9 on both. This is strange because the run-off of these two were tested yesterday at Ph 6.46. This could be due to the lower Ph of yesterdays feeding mix.
I have decided that after the flush once they start recovering I am going to start with a simpler 2-3 part nutrient line such as FF soil, House and Garden soil A+B, or maybe even Dyna-Gro 2 part (cheap and I hear good things). The 6 bottle Nectar for the Gods Im currently using has too much margin for error and I want to keep this first grow as simple as possible. However it was a free sample set, so I decided against my better judgment to just try it out. Lesson learned: go with my gut and what Ive done the most research on!

Just did some lst on the largest plant. I see some awesome potential for new growth towards the bottom that I need to get light to. Included are before/after shots.

I just added up the N-P-K ratios for the Nectar for the Gods nutrients as well as FF trio, and Dyna-Gro duo.
Nectar for the Gods-all 6 bottles used during veg/flower: 3.5-20.5-3
Fox Farms Grow Big (veg): 6-4-4
Dyna Grow Grow (veg): 7-9-5
Fox Farms Tiger Bloom (flower): 2-8-4
Dyna-Gro Bloom (flower): 3-12-6

Now, just looking at this I can see a HUGE difference in the P value. And it has half the nitrogen or less as the other two. The feeding schedule requires all 6 bottles throughout veg/flower just in different strengths.

That is a fuckton of P. Dyna-Gro Foliage Pro 9-3-6 is a better NPK for veg. 1:3:2 is fine for flower but 3:1:2 may do just as well.

I see you are in organic soil so nevermind re the synthetic nutrient recommendation. But you need more of a balance in your macros not whacked out P levels.

Yea I know. I think Im gonna go with either Earthjuice Grow/Bloom/Catalyst/Meta-K or Dyna Foliage Pro/Bloom/Protekt. Im still weighing pros/cons. I like the organic idea and people really seem to love both. The Earthjuice requires bubbling prior to feeding to get the most out of it and requires more bottles which Im trying to avoid. It does seem great though. The Dyna-Gro seems to be great as well. Ill most likely go with the Earth Juice but I tend to over analyze everthing so who knows.

or there is always dirt?
 
Im using FFOF. Yes, it has enough nutrients to support it for 3-4 weeks but after that its good to start feeding of some sort. I began using the nutes too early, but I absolutely will be using nutrients. Thats not even a question.
 
Today I transplanted the PK#1 and the WC#1 into large pots. I used a bit of this Myzo stuff I got a sample of. Its a granulated microhizea(sp?) that is supposedly good for transplanting when prinklee on the new soil and allowed direct contact with the roots. We will see. I will be grabbing 3 more of this size pots (the red ones) tomorrow to transplant the rest. They are not rootbound but a other week and they will be. The soil completely held its form when I dumped them over. This may be part of the cause for the slowed growth in the last week or so... Along with the other issue I suspect.

Im not sure whats going on but these little brown colored spots are startimg to form on more and more plants. Its only on a leaf or two of 3 differen plants now but its a little disconcerting. Other than this, they are mostly looking great still. Im hoping the transplant/flush/new nutes later this week or next week will starts turning some kf these issues around. It was also very hot yesterday and the room was up to 86 for a bit while I was working in there. Typically it holds between 75-81 (usually 77).
Im going to put some picures of the spots if anyone might happen to see this.

are you misting them? could be light burn due to magnification on water droplets.

I did the other day yea :/ i was ripping out some insulation in the ceiling of the room to install hest exhaust vents. I moved all the plants out into another room but man that dust grts everywhere. There was a light disting on the plants so i tried to clean them off best i could.
Sometimes while watering a little will splash onto the leaves.
 
Now that I think about it more your probably right here. I didn't start seeing this until after Instarted using he hid light. I never saw this while under the fluorescent. Maybe I just need to be more careful watering.
