Huge hairy bud with problems maybe

I'm guessing it's just the result of the flush, how long ago did you renute the res? If it's not a deficiency it looks like it could also be the start of some light bleaching, how far away is the top of the bud from the light?

EDIT: Excellent job on your first grow by the way, remarkable results.

 

Thats what it looks like to me, too.

Very nice grow by the way.

 

It is a very good looking grow but I think the issue is from the flush to the high nutrient dose. I would bet you went from a 0 or near 0 ppm flush back to normal peak blooming ppm's? Now you have a nutrient overdose from the drastic swing. I come to this conclusion for a few reasons. One- Any drastic ppm swing will stress the plant. Two- flushing really should still have nutrients but a much lower strength to avoid water stress on the roots aka reverse osmotic stress, causing them to drink more then they want in search of nutrients. Very little nutrients and the plant can still leach stored mobile nutes. And three- The burnt tips of the leaves shows high nutrient levels. Umm lemme take a wild guess?? Advanced nutrients??

 

If it started before you flushed, it sounds like it could have been light bleaching. a 1K watt light puts out tons of lumens at 14 inches, I've had some of my taller tops this cycle get bleached from my 600 watt at the same distance. I'd continue growing it with their bloom food, as you get closer to harvest start slowing down on the feeding until you're ready to do a final flush. From the look of the buds though you still have a decent amount of time before they ripen, almost all the pistils are still white and the calyx's aren't swelling up.

You're going to get a killer harvest if you make sure to take good care of them during these last couple weeks, keep up the good work!

 

I would be willing to bet you are having calcium and magnesium problems. Prolly wasn't getting enough in the beginning, then you flushed. This made the root zone fresh and ready for nutes but only a little is needed bcuz the roots have been cleared. Now you feed full strength and the plants roots are locking out nutrients due to being shocked! Always flush with something in the water. Cal mag works great and also sweet from botanicare, it has magnesium. Even molasses will suffice! Flushing with tap water is ok as it has disolves minerals in it. But, if you are using RO water, you must add something or else you will actually leach water and nutrients from the plant. Plant will look like it needs to be watered even though it already has been!

If your Tangerine Dream plant is ready to harvest I would flush again, then for the Red Dragon, it seems like a longer budding sativa dominant flower so personally I would stick with the week 10 schedule, and if you see the buds starting to ripen up switch to ripen then flush.

It looks like Red Dragon will be a longer flowering strain so I think you can get away with another quick flush to provide optimal smoke quality for the TD.

EDIT: looking over the pics of the Red Dragon again I can't spot a single amber pistil or any signs of them receding, it appears to still be pumping out bud growth steadily still.

 

Your red dragon could take up to 75 days per the breeders info, which means it could go 80 days easily! I'd be real careful flushing her as it could cause more problems, also, if you do flush just do a 5 day one, I never flush more than 7 days in hydro as its only nessesary in soil where the soil holds the nutes, with hydro once you dump your nutes all the nutes are gone and the plant begins to eat its leaves for food.

 

The above is true, any change you make to the res will effect the plants immediately, whereas with soil and most soil-less mediums it has a buffering period.

 

I use a microscope to see the trichomes to ensure that I have enough milky/amber ratio as well as the general overall appearance when determining when to prepare to chop, I like my weed for pain and fun so I sometimes do a split harvest where I'll grab the riper buds(ones on top) first and then wait till the rest get to that pain relief doneness of 50-60% amber.

My theory on final water for flush is, tap water if its not toxic(above 250ppm) otherwise distilled/RO and I don't bother with pH as I could careless if it is in the right zone, I'm not looking to make nutes available to the plant so why should I care if its high or low as long as its not like vinegar i.e. if you can drink it its good enough!

 

Also, keep a close watch on that big bud for mold. make sure you have a fan blowing on it 24/7.

 

3.5 ft should be good for a 1k watt light, it's good you have the vertical space to allow to raise it that much. I'm in a position where I have to just deal with light bleached colas this time around, didn't plan for them getting this tall.

EDIT: This post is worth 2 420's.

 

Has she started to recover, cause by now I'd think you should have seen some improvement or atleast no more bleaching. I've personally never had to deal with bleaching so I'm not sure about removing the messed up leaves but I think that once the problem is fixed the coloration should return. By the way you may also try lowering your ppms a couple hundred points if the problem persists as its natural for the plant to need less nutes near the end. I'd say you have atleast 2 weeks before it will be done maybe 3, you just have to keep watch and when it looks like its finishing up then do the flush thing.

 

On the removing leaves topic the general rule of thumb is leave everything that's not over 50% damaged. Any leaf under half 50% damaged should stay.

 

Hehehe that blue face is perfect!
