Hiya guys,

My grow is doing great.

3x Auto white widow dutch passion
1x Auto OG kush (free gift from shop)

Now im closing in on the end and looking for answers on how to finish them properly.

Im growing on coco, feeding 850 ppm once a day in 4 gallon fabric pots. (15 liter pots)

Roughly 2.5 liter of tap water a plant.
Canna Coco A+B 1.2 mL /liter
Canna Boost 1 mL /liter
Plagron Green sensation 0.5 mL /liter

I think I still have some weeks till harvest. They are on week 10 from germination.
The buds are fattening nicely.

Now what should I do to get them nice yellow leafs?

Which nutes do I lower? what ppm? And to flush or not to flush?
I read about only giving green sensation last 2 weeks before harvest.

This is a first - someone asking how to get yellowing leaves. It will happen. Cut feeds. Last week just RO water. They look good

Try to get some close up shots of the calyx's. As they swell the hairs will pull back in them and turn red. Most people pull the plants when the plant has 30-70% red hairs..Some people use a hand microscopes and look at the trichombe "mushroom" color. Most pick when they turn 50% milky or red.

thanks my friend. Cut feeds as in completely? and no building down? So I just continue my feeds of 850 ppm and when I think they are ready flush for 1-2 weeks?

I have microscopes, they are not close yet. Just wondering if I need to do anything to my feeding. Last year they hermied and they never went yellow.

Do you think that running 3x the pot size of plain water through coco is a good idea? (that's called leaching BTW) Ive never grown in coco but the consensus seems to be that you never run straight water in coco or are you doing that and then adding ferts?
How will that increase taste and smoothness?

At the end yes, before harvest.

I am asking how to do it, because I dont know how on coco. But I know you should. (sorry for the copypasta)

What Is Flushing And Who Should Do It?

Before we get into the reasons why flushing your plants is so important, we need to understand exactly what flushing is.
Flushing involves watering your plants without any added nutrients for a period of time — anywhere from a day or two to a week or more, depending on your growing medium — prior to harvesting. The purpose of this is to allow the plants time to use up the nutrients that have already built up within them, thereby lessening the overall nutrient and contaminant load of the final product.

We recommend flushing for growers of all types, whether hydro, coco coir or soil — though the time period for flushing will vary, depending on the medium.

The Importance Of Flushing

Though some in the industry have argued otherwise, the importance of flushing your plants has been affirmed by the vast majority of serious growers. Most experienced cultivators have tried not flushing before harvest, which has caused them to experience first-hand the glaring difference in quality of the yield.
You see, during the growing cycle, your plants store excess amounts of nutrients, salts and other compounds. If you don’t allow the plants a chance to dispose of these surplus compounds by flushing them before harvest, your final product will be much harsher and more bitter tasting. Failing to flush can also cause your product to suffer from other negative side effects, such as black ash and an unpleasant chemical taste and smell.

The truth is, not flushing nutrients before harvest can seriously compromise the quality of your high-value crops.

Check how many days you should expect to flush in coco.

Tapering off your nutrient to full water around when the plants have reach full flower will allow the plant to naturally "flush".

Once you have visual confirmation that your product "finishing up," giving you plant plain water will allow you the "yellowing" or "flushing."

People on this sight generally frown on flushing. People think that this is, more often than not; wasting resources.

But, I grow organically, and i generally alternate feeding and and watering. If i water one week i feed the next. Toward the VERY end I give them plain water+sugar for up to three weeks before harvest. I know that the last few weeks will give me almost no nutrient value and, I will be just wasting organic nutrient.

Chemical nutrient has extremely fast uptake and additional chlorophyl in the plant material will cause harshness in the smoke.

I grow in soil with chemicals and I do this pretty much as well. I just taper feeds towards the end and may water only last few days.

The only time I flush (and this is very, very, rare) is when I have a salt build up. The correct horticultural term for this is of cause leaching not the stoner term flushing.

So I guess tapering it is. How slow do you do it? I mean in PPM/day or per week?

Im not in coco mate. I have no idea what to suggest to you but I have heard from coco growers that you dont water only coco. But I have no experience in it.

Thats all pretty much bunk. Just Advanced Nutrients trying to boost their bottom line.

Just start to taper your ppms back to around 350-400 over the next few weeks as they finish.

Yeah subcools supersoil is a living soil and works well, i kinda followed his recipe this year but did a different twist with the admendments i had on hand, makes less work after you got it prepared and i fond it makes it a bit more fun

Supersoil?

I am actually thinking about doing that next year.

Just give them fresh water only the last two weeks or so. No need to taper off. Plants look great would love to see some close ups of the widow on here when it's done :)
