How to flush early varieties grown together with late varieties?

[cracka magik]

a little bird told me flushing agents are simply concentrated magnesium sulphate ( epson salt ). dont waste your $...

Have you ever looked at a bottle of flushing agent? If its anything simple and cheap its a combination of two simple sugars, not magnesium sulphate. Your little bird doesn't know shit since he can't even get his propaganda straight, he doesn't realize he's meant to be hating on calmag and not a flushing agent?

Back on topic, I'm in the same boat with a room full of plants in peatmoss hooked up on blumats and am debating whether to just keep my res filled with water and hand water nutes for those that need them or just keep the quicker finishing strains going for a bit longer.

you guys need to try organics.

Here is a plant that was fed to the end. Or flushed from the beginning, depending on your point of view. The nutes are there, but the plant isn't asking for them.

here is the same plant from clone at 58 days. The plant next to it is a reveg of a different strain that will go longer. Both are in the same soil, same size. The plant on the right is a skunkman freebie that will likely go many more weeks, while the mandala 1 is yellowing with the same timing as seen in the donor plant.

Re: tasting - any good taster knows just how highly suggestible the human palate is. If you like wine, your best bet is to find a critic you disagree with consistently, because you know what to expect. Anyone here claiming they have the power to detect flushed vs. unflushed weed that has not otherwise been ruined via overfeeding is just blowing smoke, unless you can document a blind taste test. Boasting about experience is just boasting, and in any case, I believe someone who has been telling themselves the same wrong story for 10 years is more likely to be off than a total newbie.

When someone offers you a sample, their body language, verbal language, etc... all contribute to how you experience the smoke. many taste experts are just demonstrating the "clever Hans" effect. They don possess a discerning palate, but they are good at picking up on how you already feel about something.


I'm not a hydro expert, but in this case the experience of a soil grower is helpful. If you could manage to not overdo the nutes during most of the plant's life, you would not have a problem to fix at the end.

chelated nutes work the same as organic. The plant takes what it wants to take from the nutes. When it stops taking nutes, time has come to chop...

To the OP's question - you can try running your nutes lighter, then after each flood, just go in and pour a quart of fresh water on the one plant to wash the nutes out. It would not be the same as flushed, but it would improve.

I have done the side by sides many times my first couple years in hydro, I always flush now, just plain water, no bullshit. If you run light nutes, your herb can pass unflushed, but a blind test will show it still tastes different. Personally, I deserve the best!

I see no reason to feed a plant all the way to the day you harvest. There is enough Nutrients in the soil and plant to keep her going for the last 2 weeks of it's life. You do not want a Super green plant on the day you harvest imo its full of nutrients that need to be used up. After 2-3 weeks of ph water this will get all nutrients in the medium and plant out and used up by the plant. I also grow Organic to me feeding your girls all the way to harvest is just a waste of Nutrients. If you're going to harvest in a few weeks there is plenty of food for her to finish. Adding more food is just like pouring it down the drain.

What I do in this situation is prop the earlier finishing plants up on something so they are above the water line on the table and then just hand water them. Hope this helps. peace
