This is my first grow. I chose Blackjack for its THC content, easy of growth (recommended for beginner), shorter flowering time and nirvana Seed Company recommendation from this site. I knew nothing first hand of this or any other seed. I chose feminized seeds hoping to simplify the process.
I have one room 6’ x 8.5’, divided with B/W polyvinyl on a 2”x2” frame making my veg room 2.5’ by 6’ and my flower room 6’x6’. I used 2 zippers for a door.
I have 2, 4’ T12 for cloning, under that 4, 4’ T5 (which may need to be increased).
I have a 1kw hps for flowering. It is an air cooled room with a 6” exhausts fan which currently pulls air from inside the room in to my house through a closet with a odor sock carbon filter. It is on a thermostat that comes on at about 83° and off around 75°. This helps heat my house. I’m using a liquid filled plug in heater during lights out in the flower room. Lowes are about 68°-69°. In the summer I will use this fan venting room air into my house and using my house AC to cold this area. I will add another fan pulling air from my house eve vent and exhausting in to my attic to cold the light.

I am growing organic in soil. Using Fox Farms, Ocean Forest and Light Warrior 2-1 ratio. Adding Worm casting, Blood meal, and Bone Meal. I feed once with molasses in veg and plan to feed with Bat Guano during flower and I am preparing Tea to top feed now.

November 2, I place my 5 seeds in a damp paper towel in a zip lock in the drawer. 4 seeds sprouted 1 never did.
These are pictures I took November 21. I had concerns over brown and white spots. They went away on their own. After having almost killing my clones, having them to close to my T5, I think seedlings where to close to the light.

Here is the forum link if you care to read it or see the pictures.

After 2 weeks the seedlings where placed in 1 gallon pots, as pictured above. After 3 more weeks they where placed in 3 gallon pots. 2 weeks later, December 20 they where placed in 36 hours of dark to start flowering. They have since been on 12/12 lighting. I had concerns about light filtering though the zipper from my veg room. After an attempt to stop the light, I decided just let it go and see. As you can see the small amount of light does not seem to affect the plant development.
PH of water is 6.5 and run off from plan is also 6.5.
So far all appear to be female with a bushy ,thick, Dark Green Canopy forming. All where topped, however, 2 did not split, 2 did. 2 have 1 cola each, 1 has 3 and 1 has 4. The tallest is 28” and has grew from 14” on December 20. I should have planted in larger pots, but it may be a little hard to repot this by myself.
These pictures are from 1-8. 7 weeks from seed through veg and 19 days in flower.



As you can see from picture b, d and , several leaves are turning under with a wilt like appearance. It appears to be damage from aphids, spider mites, or some other bloodsucker, however, there are none to be found. An I have seen my share in the vegetable garden. Other than a few leafs turning under everything is fine. Hopefully it is nothing.
Any advice, suggestions, criticism and help is appreciated.
Thanks,
Snew

So people are looking even if not commenting. Here are a few more pictures. If you see any reason for the wilt please pass it along.

weird that doesn't look like blackjack. Blackjack is 80% sativa and yours looks like 80% indica. curious?

Your leaves are telling you they are getting too much water. That soggy curling under is from too much aqua senior.

I water every 3-4 days. ¾-1 gallon in 3 gallon pot. I get 1-2 inches of run off of each plant. With other plants when there is too much water it seems to effect the whole plant not just a leaf here and there.

Subscribed, I'm interested in growing this some time this year. Was staring at it hard when I ordered Snow White, White Rhino, and Northern Lights.

That's not overwatering -- your watering sched might even be a little slow for plants that size under a 1K.

What you're seeing is the early onset of overnutrition, or the effects of too-early use of bloom food. The Foxfarm advice to start tiger bloom right at 12/12 is bogus. MJ still needs a lot of N for stretch growth, and TB fails this. I'd go back to your veg nutes, at least until stretch slows down.

I added at bat guano, worm casting, molasses tea. After these pictures where taken. It is the first thing I added in flower and I only added molasses at 3 week veg. Thats it.

I'll bet that's the issue. You need to keep the N-P-K balance closer to "veg mode" to support stretch. Try replacing the high P guano with high N.

Check this link for the same lowdown from someone who's grown massive nugs for decades..

I also had worm castings in the tea to give extra N for stretch. I only added 2 hours ago. The pictures were taken before that so I don't think that was effecting it. The only other feed was molasses 1/2 strength at 3 weeks veg.

So, they've only had one high-P feed 2 hours ago?

Plants take days sometimes to show response to soil and nutrition changes. Stand pat for awhile.. it's really early in the onset of an issue. You've got time, and oftentimes when problems come up, it's best to simplify and coast rather than get caught in a cycle of applying one correction atop another.

Thanks, that looks like what I'll be doing!

your plants dont look bad dude, ill stay posted. i use biobizz organic nutes, NPK 826 thats easier than making tea and cheaper. i keep it simple because it prevents complications. all that extra Phoshorus is gonna build up in the plant because it is not using it. let it run its course and flush then use a fert with a NPK of around 826 or similar ratio. use that tea for flowering, its perfect!

Thanks, right now I think I'll stick to natural stuff. I just started a worm farm so I'll have only a little guano and molasses to buy.

it is natural man, im the same im not gonna smoke chemicals. organic ferts rule! but then bat shit is good, you need a selection of bat shit. high N and high P. when you planning on flowering those plants?:leaf:

I'm at 3 weeks into 12/12 light now. Took a nice picture of buds forming last night but could not upload it for some reason. I just tried again and couldn't upload it. Tells me a security token is missing. I'll take a new one tonight after the lights come on.
