Feed them up until they are ripe then flush them if you wish.

Personally I do flush them, I've invested to much time and effort throughout veg and flower to fuck it all for a few days of water.

Just to be clear idk if it makes any difference I've just always done it... as above.

Personally in coco in the final few weeks you can watch your runoff climb in EC if you don’t reduce the strength somewhat.

personally during the last few weeks I gradually reduce my feed to approx what I started feeding them with. Around 0.6-0.8EC which sees me reduce from approx 1.0-1.2 so finish at approx half the strength I was previously feeding.

The one thing to note about nutrient companies is that they are selling you flushing products. In the case of the one you mentioned it's called Plant Magic Flush. Buying this stuff benefits them so you can imagine they have some interest in getting you to flush. It earns them money. So you can listen to growers who have no skin in the game or listen to those who profit from you flushing. Your call, good luck. Smart to ask though, gotta give you credit for seeking knowledge on the subject and not just blindly following the advice.

Many of the nutrient companies feeding charts have you overfeeding. Then they have you use another product to wash out what they have been telling you to feed your plants. 99% of the time you can cut those damn feeding chart amounts in half. Some are literally over the top with the high EC they have people feeding. Then people wonder why their plants are all crispy fried 5 weeks into flower.

And always there is someone to chime in and say add calmag. Despite the fact that the grower is probably getting double the Ca and Mg needed with their 10 bottles of stuff. It's too bad that there is so much misinformation in the cannabis growing industry. The majority of issues growers have is from improper feeding of too much stuff. It's always add more of something when taking something away is the correct thing to do.

Yes I lower my ec accordingly at the end, however ripening doesn't sneak up on us as you know so when I plan to chop I give them water for the last few days, the intension being that it'll have used up anything available.

If you’re feeding more than 1,000ppm per feeding, you will probably need to flush. Nutes leave residue behind in the soil. I recommend testing the ppm of your runoff routinely. I used to feed my plants way too much, and even though they didn’t burn, flushing was essential. One time we measured my runoff and it was over 1800ppm. This was also ten years ago, I’ve since learned how to feed. In the last 7-10 days, water your plants and see where the ppm is at. If you’re above 30ppm, rip up the top soil and run water through until you’re under 30ppm. Then let the soil / medium slowly dry before harvest. Before you chase me down with pitchforks, I live in a weed-centric city, and have worked with some professional commercial growers. These guys all feed their plants way too much. They grow the biggest buds possible. They all flush too, even today, if one of them doesn’t flush a harvest, it’ll sell for $250 / pound because it’s burning black. So I guess it really is a matter of how much you’re feeding, not whether flushing works or not.

My personal opinion is if you're growing organically you should flush because you're a hippie and it's going to harsh your vibe every time you take a toke. Everyone else should keep feeding their plants at least half strength because otherwise you will be starving them at a critical stage.

Burning black has already been proven time and time again not to be caused by over feeding.

the buds don’t store nutrients that’s a fact.

buds burn black when the dry and cure hasn’t been performed properly or when the bud has been laced with sugar water!

Yes. Your grow medium could retain a lot of the nutrients / salt buildup. You’re not gaining anything by feeding the plant in the same 7 day week you’re harvesting. Nothing.

No, you’re wrong. This isn’t a healthy debate, I supplied the OP with proper advice, based on knowledge and plant education. I’ve made every mistake and learned from all of them since 2007. My advice is sound. There isn’t a reason to feed the plants in the last week before harvest. Monitor runoff ppm, water accordingly.
