GDP - 2 Weeks Flowering - To Lollipop\Prune? Advice Needed

What's up, everybody?

I'm running a 600w SOG and I'm 2 weeks into flowering right now in a 4' x 3' space. 13 lucky GDP ladies in Ocean Forest soil. Running the 3-part Fox Farm nute line with Cal\Mag & Superthrive. This is my second run. First SOG. The ladies seem to be done stretching and they're at about 2 ft. I would say.

My question pertains to pruning. I haven't pruned at all yet, only the leafs that have died. I have a lot of undergrowth and a lot of branches stretching up towards the canopy (but don't quite make it) that don't seem like they are going to hold much or yield much. I've been reading tons and tons of information about lollipopping and can't seem to make a decision. I'd really like to lollipop these ladies as the structure of the colas seem like they're going to hold a lot of weight with all the tight nodes being up near the canopy.

Isn't lollipopping in flowering going to put them into shock? I can't make up my mind! Regardless, even if they weren't cramped, I still feel like all of the undergrowth is just a waste, but I'm nervous about hacking it all off as I had a hermie last go around. I'd like to trim the bottom 1/3rd of the plants to allow for optimal airflow and to concentrate the energy to the colas. I've read from a few people that they lollipop two weeks into flowering, most do it in veg, and I've also read from a lot of people in different threads that say don't trim anything in flowering as it can cause a metabolic imbalance and really hurt the plant.

What should I do to optimize yield and increase airflow for the ladies? Thanks for all the help. As an old OG refugee, IC has really helped me out a lot!! I commend you all.

Also, the Tiger Bloom and Big Bloom flowering nutrients drop the PH of my tap so much. I use a drop test kit, and with two gallons of water that have sat out overnight to evap. chlorine, I'm using almost 5-10 ml of PH up to stabilize it to 6.5 - 6.8! In the first two weeks of flowering I've been hitting them with a little bit of FF Grow for N, Tiger & Big Bloom, and some Cal-Mag. Regular water every 3rd watering. I'll probably just start the straight Tiger & Big Bloom feeding schedule now as I'm heading out of two weeks and I feel like they have enough N in them. I stir the water really well before adding each nutrient. Should I mix the nutes a day in advance? Also, when done watering sometimes I find some gritty salts in the bottom of the mixing bucket. I feel like I'm doing something wrong and I definitely feel like teaspoons of PH up is not good for the water.

Might try to get some pics up to help out. Any advice would be awesome. This is definitely a lot of fun for me. :jump:

Any branches with little bud sites on them that aren't receiving enough light or that u dont think will get big enough chop now. This is the time to do it.
 
Maybe an experiment? If you are constantly going to be running GDP in the same room/atmosphere then why not find out which works better and then reproduce it over and over. Just a though though.

This is sort of what I was hoping to hear from most people. I'm just afraid trimming to many branches from the bottom 3rd of the plant will send it in to shock. I really just don't want a hermie, hehe. :fsu:

SirSmokeALot23 - The cuts were from a friend and that friend has since gone back out west. Perhaps he'll be back in time for the next run, but with no room for keeping a mother right now it doesn't look like I'll be running her all the time. I wish though! A little slow in veg, but I've never seen a plant pack on resin so quickly in just a couple days of flower, and she has a lovely smell to her right now as well.

I'm going to try and lollipop the ones that need it really bad in the next two days or so and keep the other half of them unpruned except for what's really necessary. Do a little side-by-side. Any more advice is welcome. Thanks, guys!

Do it to them all, you won't be sorry. I prune Pistilwhipt style which is I guess what you are calling Lollipopping. What a funny name for it, never heard that before LOL.

Your fear is understandable, everybody is scared at first to prune off so many bud sites, but in the end, they are always glad they did :D

check out www.urbangrower.com for some video step by step of pruning & flagging.

chock full of good stuff...

Nice! This is a pretty cool site. Definitely some good information. You can check the pruning video here.

Still not sure what is going on with my nutes. I'm going to try mixing each nute into a smaller amount of water, and then mix all of the seperate waters together.

Going to try and trim later today :nanana:

Well I took off the bottom 3rd of most of the girls. I left a little here and there and didn't want to take too much. Taking a few stalks off each lady seems like it would be a lot of stress, so I was careful not to take too much. Let's hope I didn't ;)

Cleaned up all of the dead growth and most of the leaves with purple stems that looked like they were on their way to dying. Currently in day 16 of flowering, the girls can definitely breathe MUCH better now. Hit them for the 3rd time with some Einstein Neem extract as well; this will be the last time I treat them. I applied Neem to them about a week apart 3 different times. No more mites I hope.

Mixed a 3/4 strength super thrive dose with a 1tsp/gal dose of cal-mag and 3tsp/gal dose of big bloom, then mixed separately in a dif gallon of water a 1.5tsp/gal dose of tiger bloom. Mixed both well, added both to one bucket and stirred that well. 3 gallons, soaked them. Seemed easier to PH a little bit, but still see some matter in the bottom of the bucket after watering.

Next water will probably be plane water with a full strength of super thrive to help with the stress. Don't think I need any more FF Grow (N), but not sure. Anything else I can do to help ease the stress?

Perhaps I should have done all the trimming over the course of a couple days, but it's such a bitch to pull them all out of the room and put them all back, so I did it all at once.

Well, I may have taken too much off at once but I'm not sure yet. Just real nervous hehe :joint: I've done more research on the pistilwhipt technique\lollipopping pruning technique, and I've drawn some good conclusions so far:

1. Prune last week of veg and maybe first week of flower
2. Prune over time, not all at once (to reduce shock)
3. Leave the fan leaves behind


- Also, I'm not sure if it was better to prune just before lights out or not. I wonder what the scientific verdict on that is. I just pruned and sprayed them all at once to kill two birds with one stone.

The only thing that's making me a little nervous is that most of the plants are slightly "praying" upwards, as in the growth up top is angeled almost at 30 or 40 degrees, some a little worse than others, but nothing too crazy really. I've just never seen that reaction to stress before, unless it's maybe heat, but I've read a little about it being magnesium too? They get enough of that I think. Either way, as long as it goes away in a day or two I think they'll be fine. Keeping a close eye for hermies.

It could just be me, but I swore when I saw them this morning I had seen some explosive growth in the main bud sites\colas on some of the bigger, stockier plants in the garden. I pulled a runt to allow for more space, and every inch of them is practically getting good light. Currently with 12 ladies at 17 days and looking pretty fat, an ounce per cola doesn't seem too overrated, but I'm shooting for 8+ with a minimum of 6 being a failure heh. All I've been reading about is how GDP doesn't yield too well.

Supposedly, this GDP is a cross between the two, so that it yeilds better and purples up just as nice. I don't believe it, but I do think it's GDP one way or the other.

They are at about 20" - 25" with the pots. The hood is vented and rests about 6" off the canopy, so the bulb (hortiluxxx) prolly rests 9-10" off the canopy. I raised it a little today because I didn't feel like the spread of the light was hitting the perimeter as well as it could be. Choices.

I've been reading this thread in the infirmary called "Fox Farm PH Problems" with someone who has the same problem I'm having. I wouldn't say mine is much of a problem, other than that I use a ridiculous amount of PH up to get the water stable, or what seems like a ridiculous amount to me. Also, something is falling out of the solution in the water.

I thought about this a lot today. I think, because I'm in the transition of introducing flowering nutes yet still feeding veg nutes, that when I mix: the Tiger Bloom first, Big Bloom next, then Grow and\or Cal-Mag last, that the PH drops significantly with the TB, then as the PH keeps dropping with the addition of more nutrients that lower PH, perhaps one of them is falling out of the solution because it won't stay in a solution below 4.5 or maybe say 4? I'm going to try mixing 3 gallons worth of each nute into a seperate gallon container, PH the solution, and then mix each gallon into the other. That way, each solution should be at 6.5 - 6.8 and neither of them will fall out. 6.8 allows the plants to feed on the Cal-Mag as it locks out at < 6.5.

I plan to feed with 2tsp/gallon Big Bloom and 1tsp/gallon Tiger Bloom from here on out. Every 3rd watering they get regular PH'ed water, sometimes I'll give them Cal-Mag too if it looks like they could use it. I've never flushed before, as it really is just a bitch with the space I'm working with to get them all out, so I try not to go too heavy on anything.

I really would like to get some pics up when I'm not feeling so worried. Not a new member by any means, just switching things up because I don't trust the infranet. :dueling:
