Should I flush?

Need some advice again in using fox farm ocean forest. I’m almost at week 4 of my grow nutrients and starting at week 5 (not sure if all nutrient schedules are like this?) But it calls for a flush in between week 4-5 with sledgehammer My one big one is been growing from seed for 2 months an few days with its first dose of nutrients given on 02/19/20 and I started at week 2 of the doses on 02/25/20 I gave week 3 of nutrients I had a bad case of deficiency/s since I skipped a week started alittle lite and did full dose on week 3 should I do the flush? I’m kinda worried about the deficiency/s coming back and I’m also not to sure how to flush and how many gallons to flush with at all I’m in a 3 gallon pot which I’m gonna finish everything in I’ve been giving my clones which I have no idea how old they are I transplanted them from a buddy on 01/15/20 and been doing the same with them as the other which they seem to be doing pretty well any and all advice and opinions are welcome

skip to section 3.9 and read from there!

Recommend still running water through medium a week or two prior to harvest to get rid of any salt build up

Flushing is a waste of time, just nonsense endlessly repeated by people who grow without thinking about what they are doing.
There is no other crop where the growers starve the plants.
Paying for expensive nutrients exactly the same ...... entirely pointless ...... fertiliser costs $5 for 1Kg, if you pay more you're just being daft.
There's no other crop in the world that needs specialist fertilizer.

Flushing is a hot button on these sites and usually the debate centers on flushing out fertilizers to get a smoother smoke. As it turns out, once fertilizers are taken up by a plant they don’t come back out. It doesn’t work that way. So flushing to reduce fertilizer in the bud is not going to happen.

What will happen with flushing is that the plant will be forced to use up any reserve sugars and starched it has stored because without fertilizers it can’t make more. Whether this reduction of sugar and starch has an effect on taste I don’t know. If you flush for too long or too early you probably will reduce yield though. It doesn’t take that long to use up sugar and starch reserves.

This may explain why some growers advise keeping plants in 24-48 hours of dark before harvest, again forcing the plant to burn reserves because they can’t make more, or harvest right at dawn when the reserves are in storage in the roots. Also this may explain why people who flush say the ash is more grey than black, less carbon.

Just for what it’s worth. Again I don’t know if it makes a difference.

Yes flush, I've used the same fox farm nutes. When you switch from one nute to the next nute on the feeding schedule flush with sledgehammer. At this point its not about flushing for flavor or to make a smoother smoke, its about trying to remove what could be left over in the soil from the last nute used. Fox farm can be a tricky system to work with. I also recomend only going with a maximum of half strength to limit salt build up.

I agree flushing out the medium is a practice that’s helpful but once you start believing that you can flush out the nutrients in the plant itself is where most people are wrong. But once again I’m not a scientist of any sort just going off of what studies there are based on this topic
