33 Days of 12/12

awesome good job and they are looking good i bet they smell great

Yes they smell lovely, its a good thing I got the carbon filter or my whole place would be skunked out. Its been 48 hrs since I fed them with a high PPM nutrient dose and there is still no burn so I am in the clear! Next watering, plain ph'ed water, the watering after that we are gonna go up a little on the ppm of the nutes... 1400? Did a little bit more stabilization of the branches on the Purple Cadillac and pulled a few side branches in just a bit, Dont want those buds swelling on me and sticking to the sides of the tent! New pictures by the weekend.

Day 34 of 12/12

Everything is getting bigger, more trich production as well slight swelling of bud sites. Took some photos out of the tent, the Grand AK's old leaves look so awful but she is recovering, its just sad the leaves will never return to their formal glory. The Purple Cadillac is eating some of its yellowed leaves which is natural and very cool to watch. Watering set for tomorrow or Friday, the pots are getting lighter but u can still feel some moisture under the top of the soil and see a bit through the drainage holes. I would say we are a little over a 1/3 of the way through flowering from what I can see.

That coloring looks really good, despite what it represents. Subbed for more HD pics!

Day 36 of 12/12


Watered today, Purple Cadillac was getting some more yellowing as of this morning so I watered with nutes, 3tbs of Tiger Bloom, 2 tsp of Cal-Mag Plus in 1 gallon of water. First I put through a gallon of Ph'ed water to check my soil, PPM was 650, after watering with nute water, PPM 1500. Put 1 gallon through the Grand AK, PPM 450, watered with the same nute solution as the Purple Cadillac, PPM of soil in Grand AK = 1000. I know I need to skip a feeding, but they just keep drinking it up, so I will skip nutes next watering to prevent burn if I get any off of this one. Also I am getting some purpling on some of the yellowed out leaves, kinda weird, any ideas from the people reading as to why this is happening?

Trimmed a few fan leaves and leaves that were yellow to allow a bit more light through, still so many leaves so no worries about lack of fuel cells haha

Phosphorus (P) Mobile Element and Macro Element

Phosphorus is an essential plant nutrient, and since it is needed in large amounts, it is classified as a macronutrient. Phosphorus is a MAJOR important nutrient in the plants reproductive stages. Without this element the plants will have a lot of problems blooming without proper levels of Phosphorus.


When your plants are deficient in phosphorus, the edges all around the leaves or half of the leaves can be brownish and work its way inwards a bit causing the part of the leaves to curl up in the air a bit. Fan leaves will show dark greenish/purplish and yellowish tones along with a dullish blue color to them. Sometimes the stems can be red, along with red petioles that can happen when having a Phosphorus deficiency.

So pretty much the overall dark green color with a purple, red, or blue tint to the fan leaves is a good sign of a Phosphorus deficiency. Having Cold weather (below 50F/10C) can make phosphorous absorption very troublesome for plants.

Parts affected by a phosphorus deficiency are: Older Leaves, Whole plant, Petioles.

Phosphorus fluctuates when concentrated and combined with calcium

I suggested earlier that your night time temps were low but you thought they were fine, so now that’s ruled out how are you testing the ph and if it's a pen are you calibrating your it. I’m sure you have already mentioned this but I can’t remember, I read too many different threads.

Today I was reading up on Mr. Lucas and his growing tips, he wrote about ppm runoff and again for the likes of me I can’t remember exactly where I read it but he said the ppm runoff for a plant flowering as far along as yours is should be a lot higher than what yours was today. With that said I think your fertilizing today should have taken care of any hunger issues.

On a further note looking at your data, the trouble is with the Grand AK and it has the lowest ppm of 450 which is really low even for a young vegging plant or a new bag of unused soil for that matter. By any chance did you take the PH of the runoff to make sure it’s not a PH lockout of Phosphorus?

Anyway other than the phosphorus deficiency weather from cold temps or the lack of food everything else looks great. I love how tightly the buds are growing together and I think the plants are going to be heavy yielders.

Problems with Phosphorus being locked out by PH troubles
Cold wet soils, acid or very alkaline soils, compacted soil.

Sorry if this post sounds a little moody.

Thanks for the phosphorus info bro, as far as night time temps, they are staying around 63 which is 4 degrees warmer than early this year. My highest temp is 86 but it tends to stay around 83 degrees. As far as the ph is concerned, I did test the runoff of both plants and they were around 6.4 with a test tube test, I do have a ph pen but its not calibrated right at all so I need to pick up some calibration liquid sometime soon, I am having to raise the PH of my nutrient solution after its mixed it is way below 5, so I have been bringing it back up to 6.5 before watering. The PPM levels for late flowering I have seen are around 1600 ppm, is that too low? I have been trying to bring the ppm up, my previous watering ppm of both soils was around 1000, but after testing it with this water it was super low, so I guess the plants are very hungry buggers. Im gonna test the ppm again next watering and if it comes out low I am gonna give them another dose of nutes, I am just scared i am gonna burn them and further worsen my results. Thanks for the hopes of a heavy yield, that would be great for a first LED. I appreciate the comments and advice as always bro.

Quick Update:

Still no signs of nute burn, checking the ppm of the run off next watering and if its under 1000, Im going to go ahead and water with a 1800 PPM solution. We are a little over 5 weeks into 12/12 so its time to give them a healthy dose of nutes for the next 1-1.5 weeks and then see where we are at as far as maturity of the buds are concerned, if we still got a little ways to go, we still water with nutes at a slightly lower dose for another week, then pure ph'ed water til she is done. Happy Growing Everyone!

A peak inside...

 

[slinger36s]

Seeds are here!

5x Fem The Church (GH Seeds)
1x Fem Chocolate Heaven (G13 Labs)
1x Fem Blueberry Headband (Emerald Triangle)
1x Fem Critical + (Dinafem)
1x Fem White Widow+ Blue Berry (Female Seeds)
1x Fem Jack Diesel (Positronic Seeds)
1x Fem Grapefruit (Positronic Seeds)
1x Fem AUTO Super Cheese (Positronic Seeds)
1x Fem AUTO Cheese Candy (Delicious Seeds)
2x Fem AUTO 60 Day Lemon (DNA)
2x Fem AUTO 60 Day Wonder (DNA)
2x Reg Bubba OG (Humbolt Seed Organization)
2x Reg Gogi OG (Bodhi Seeds)

I wanna run the six AUTO's and in the last 2 weeks of that pop 1x FEM The Church and 1x REG Gogi OG and 1x REG Bubba Kush. Hopefully I get atleast one male out of the regular seeds so I can harvest the pollen and cross one of them up with The Church. Thats the idea, we shall see what happens, come down to this. I have way to many seeds and not enough space or time haha.

Took a quick look in the tent, removed some lower completely eaten and crispy lower leaves. Everything is looking more fat and frosty every day, had to tie a couple more branches to the stake in The Purple Cadillac. The pots are getting lighter should be good to water by Wednesday.

40 Days of 12/12
Watered today same regiment as last watering and I just can't understand for the life of me how my initial run off levels are still about the same as last time. I put water at 1700 PPM in both of them this time. The initial run off from the PC was 826 and the GAK was 457. Either they are support hungry or I am doing something wrong.

Nice grow, things are looking great. I know this problem is way behind you now but I think from looking at the first set of pictures this is a Phosphorus deficiency. And looking at the second set, this is a Potassium deficiency. Anyway things look great now, I’m looking forward to flower and I bet you are too. Nice work on the LST, your fingers must hurt from tying all those little knots. lol

There’re hungry man, that just goes to show you how underfed they really are; the leaves speak the truth. Back when your journal first started and you plants were very young I thought you were holding back on the ferts then. You can starve a plant in veg and it will be fine, except for slow growth and a little yellowing that can be mistaken for a Cal-Mag deficiency, but after the second week of flowering, if you starve a plant the leaves are going to look just like yours do now. The plant sucks the “good” out of the leaves to feed the flowers.

Although next watering I wouldn’t give more ferts, I would give straight water. You have big plants in small pots which in my opinion are always going to give you a harder time getting the feeding program right and keeping the soil PH in check, I’m not saying it can’t be done, it’s just a little harder, that’s all. I would almost guess that your soil PH has bottomed out, if you had an accurate way of taking a reading.

Well we are into the flowering phase of this journey, so excited to see some buds starting to form! Watered both plants with Ph'ed bottled water with 1 tsp of Cal-Mag Plus in each gallon of water that was fed the plants. Measure my run off water and the Ph was around 6.2 which is a little lower than I would like so I will be raising the ph of the next watering to 7 hopefully that will get it to raise up a few to around 6.5ish. Took a couple photos during watering, you can see that the middle of the canopy of the Purple Cadillac was bleached out a bit, I think this was due to the light being 4 inches from the canopy but if I am wrong or you have other thoughts please chime in. It has been a little over 2 weeks since I transplanted into the new soil and the next watering which I think will be in about 4 days I will be giving them both 1/8 strength bloom nutes (Tiger Bloom).

This post shows you’re under feeding and the beginning of the PH problem that is probably leading to the phosphorus deficiency. At that point in the grow you should have been giving full strength.

Man I’m not bashing your growing skills here, I think you’re a great grower and are well on your way to a plentiful harvest. Sorry I don’t have any pictures to post to prove my advice is creditable; I quit growing for myself after 14 years.

Edit: Phosphorus starts to be locked out at 6.4 and under.

First off thank you for your advice it all makes sense to me. I kind knew I was under feeding but I was scared of the nute burn. Next grow I shall be more on top of it for sure. I enjoy reading your thoughts it doesn't come off like your an asshole or anything just good info. I'm definitely Not feeding next watering but I am purchasing some Big Bud and and some other kind day of carbohydrate product for the watering after next. I've been checking the ph of the run off water constantly now and it's staying between 6.3 and 6.5. I'm still getting some purpleing and yellowing in the PC. I just want them to make it through to harvest.

A little day 41 of 12/12 BUDPORN

 

[Chronikool]

Starting to look top notch!

 

[slinger36s]

Thanks man, I just did some defoliating to try and get more light to those nug spots. We are almost in week 6 of 12/12, 3 weeks to go! The girls love the last dose of nutes!

Day 43 of 12/12

Watering Day! Pots were super light so I decided it was time, unfortunately I lied (sorry Curiosity2) I put a gallon of ph'ed water as usual through, tested PPM and they were the same as last time Grand AK (432) Purple Cadillac (986) so I decided since they were so hungry and I only have 2 weeks(ish) to give them nutes before 2 week flush and harvest I gave them both nutes again.

1200 PPM/ PH 6.5
2 tsp Tiger Bloom
2 tsp Overdrive

Still no signs of nute burn since last watering so I think I am gonna be good. Took hella photos, cut it down to the 21 best, sorry for the bud porn haha .....not.
