I have actually been using full strength cal-mag throughout the grow. Since I went to flower I have put a lil extra in.

What kind of temps are you running? If your in the high 70s low 80's you may try cooling things down a bit to slow the transpiration rate. I get the same thing under my WC lamps. I think it's because we can get the lamp so close.

Yeah it sucks, the plant is a monster -- the biggest I've got. I bet I could have easily pulled 8 oz off it.

From my experience -'ve come to the conclusion that the tallest strongest are almost always males. Sorry to hear about the male.

They are high 70's low 80's...I backed off the cal-mag a bit, we'll see

Yeah that is the same conclusion I have come to from reading the forums. I forgot to take pictures of it, but I chopped the 4 main branches, took the plant out of the room and put it next to a window. Hopefully I'll get some pollen so I can breed it with my sprouting milky way.


The L*D isn't looking so hot. It is still growing but the pH issues got to it. The spots continued to spread and now alot of the larger leaves are mostly brown. To make matters worse I ran out of pH up...the new bottle came in today. I fed with 8.0 pH'd water and the run off was around 6.5....doesn't sound good if you ask me. This is after a 20 gallon flush a week ago...has me worried. Any words of advice or reassurance would be greatly appreciated.

What will this do to the final yield and quality?
 
Help!!!

OK so the spots are still spreading. I am afraid I am going to loose the plant if this keeps up. Can someone please help me out here?

I am thinking about putting it in the shower for an extended flush...will this help???
 
Yes...do it no...not later, right now. A flood of biblical proportions is called for. With the numbers you posted, I'd put 1/8 cup of dolomite lime per gallon of soil before You even start flushing. Sounds like your soil PH is way low...plant death low, and immediate action is required. Flush the hell out of them, with lime mixed into the soil first if possible, then we'll try and get you back to a solid PH level. Going to be tough, they are pretty roughed up, but I've seen miracles before.
 
Ok I just put it in the shower...my hot water heater coil went out yesterday, so is will have to do with cold water...

I have been thinking, I have been using myco and bacteria. Could this be what is causing the pH to be so low? I have noticed that all my plants have very low pH's. I added dolomite lime into the initial soil mix...
 
The plant has been in the shower for close to 2 hours now. I am going to let it run for another hour; until lights out. Then I am planning on feeding it.

Is this an appropriate course of action? What other steps should I take?

Give it a little chance to recover before throwing more nutes at it.:scratchinghead: Looks like it's had more than enough for the moment.

Did you do the dolomite lime?

Yeah I added the lime but I think that it probably got washed away. When i re-potted in the 5 gallons I made the mistake of tamping the pots to get more soil in. Compacted it a bit so I don't have the best drainage rates.
 
do as SOthern stated, and add the lime along with the good flush. And just make sure you wing them into their new regimine, and you should be all good. But keep a close eye on them and dont rush into the nuterients. Jumpin the gun can cause death. But you got great support here and can ask all the questions you want. and get them answered. Watching and sorry about the delayed response.

Thanks man. I appreciate the help. I'll feed it with 1/2 strength nutes and 15ml of rhizotonic tom. morning.

To both you Butcher and WOF, thanks for your responses about the fem'd seeds. I did some research on the STS and it seems simple enough, but the silver nitrate is pretty expensive. Do either of you know of any company that just sells the STS solution?
Butcher, sorry about your pipes but I guess it wasn't too much of a hitch as you didn't have to cut the power. Good luck.
 
You can make your own femmed seeds with a couple bucks worth of Gibberellic Acid easy enough. And you can get it at almost any nursery or garden supply store.

The colloidal silver method does work but why go through the expense and trouble.

Also, i ripped this off from a post on another site so feel free to remove or edit it if that is a no no. I know i cant post links to other grow sites.

Creating feminized marijuana seeds is an art, there are a few different methods of application. I have written about some of my different methods of making cannabis seeds in previous HIGH TIMES articles. I have use gibberellic acid, light stress, ph stress, and fertilizer stress to force my plants to make marijuana seeds. All these methods are harsh on the plants, and some like the gibbrellic acid, are not organic. In my search for cleaner more earth-friendly ways of working with the cannabis plant, I have found a new way to make feminized cannabis seeds.

Feminized seeds occur as a result of stress, other than genetics. All cannabis plants can and will make male flowers under stress. Certain strains like a higher PH, some like a lower one. Some like a lot of food, some like a lot less. There is quite a lot of variety in marijuana genetics, and you can't treat every plant the same way.

It takes many harvests before you really get to know a particular strain. Just like getting to know human friends, it takes time. I have grown strains for a decade and am truly getting to know every nuance the different plants exhibit. I can recognize them from a distance. I must say that I get a lot of help from my friends, both in making marijuana seeds and learning new and better ways of working with this sacred plant.

I named this new method "Rodelization" after a friend who helped me realize and make use of this way of creating female cannabis seeds. After growing crop after crop of the same plant in the same conditions, I noticed that if I flowered the plants 10-14 days longer than usual, they would develop male "bananas". A male banana is a very slight male flower on a female marijuana plant that is formed because of stress. Usually they do not let out any pollen early enough to make marijuana seeds, but they sometimes do. They are a built in safety factor so in case of sever conditions, the plant can make sure that the species is furthered.

To me a male banana is quite a beautiful thing. It has the potential of making all female pot seeds. Many growers out there have male banana phobia. They see one and have heart palpitations, they want to cut down the entire crop or at least take tweezers and pluck the little yellow emerging devices out. I call them "Emergency Devices" because they emerge at times of stress.

In the Rodelization method, the male banana is very valuable. After growing your female plant 10-14 days longer than usual, hang them up to dry, then carefully take them off the drying lines and inspect for bananas. Each and every banana should be removed and placed in a small bag labeled very accurately. These sealed bags can be placed in the fridge for one to two months and still remain potent.

For the second phase you need to already have a crop that's already 2 ½ weeks into flowering. Take your sealed bag of pollen out of the fridge, and proceed to impregnate your new crop of females. To do this, you must first match the female plant and the pollen from the same strain in the previous crop. Shut down all the fans in the grow room. Then take a very fine paint brush, dip it in the bag of pollen, and paint it on the female flower. Do this to each different strain you have growing together. I have done it with ten different kinds in the same room with great success.

I use the lower flowers to make weed seeds, leaving the top colas seedless for smoking. This method takes time(two crops), but is completely organic and lets you have great quality smoke at the same time you make your female cannabis seeds. If you're one of those growers that has never grown marijuana seeds for fear of not having something good to smoke, you will love this method.

You can also use this pollen to make new female crosses by cross pollinating. The older females with the bananas can be brought into the room with the younger, un-pollinated females when they are three weeks into flowering. Turn all of the circulation fans on high, and the little bits of pollen will proceed to make it around the room. Do this for several days. Six to seven weeks later you will have ripe 100% female seeds; not nearly as many as a male plant would make, but enough to start over somewhere else with the same genetics.

As a farmer who has been forced to move his genetics far away from where they started, I know very well the value of seeds. My friend Adam from THSeeds in Amsterdam has a motto that I love to borrow these days: "Drop seeds not bombs".
 
Kiwi...for what it's worth. SouthernWeed saved our grow with his advice and I would follow it to a T. We did a heavy flush too, but didn't feed again until after TWO flushes. Flushed twice, then fed with t tsp epsom salts and then with 1/2 strength nutes after the soil was allowed to dry out some. Feeding your plants should not be your first priority...getting the pH (or soil toxicity down) is your first priority. Good luck.

That is correct, you don't want to feed them yet. Let the soil dry for a couple days, then flush again. After the soil dries again, restart your nutes at 1/2 strength. In your situation, I would not add ES yet, lets level out the soil PH to between 6.3-6.8 and restart some feeding to see how they respond.
 
SoutherWeed: :adore:..picture perfect response..

KIWI: what NIC. Quoted out of that article is good. However, the only issue using naners is the hemaphrodite gene can be passed down. And as I stated before, it completely possible to work it out, it just takes a while. +rep Nic.

I did the 3 hour shower flush, let them cool off overnight and then fed 1/2 strength at 8am when the lights came on. The initial bit of run off from the feeding was at 7.0somthing and a little later it was at 7.8-9. oops!!! Should I reflush?

EDIT: It did seem this morning when I went to feed that the tops had significantly more pistils showing...

@ southerngrower, I am wondering if you could give me a run down on MAINTAINING proper soil pH levels, as well as some info on how to correct pH imbalances?

thanks for all you guys help

I looked into gibberellic acid and although it is cheap I don't think its as reliable as I would like. About the prolonged flower...I would prefer not to have to wait for a full cycle to possibly get pollen, so the STS method sounds like the best bet IMHO. I will probably do a comparison of the 2 methods though. Thanks nic.
