I am a new grower. This is my first grow with two plants . I am in the third week of flowering. PPM readings are too high. Using “Fox Farm Sledgehammer”. After flushing, should I just water through or would I use nutrients if prior to flushing nutrients were used and ppm was high(4000+ plant 1) 1000 plant 2 )I’m believing that I would consider the flushing as just watering and once that dries out completely to pick up as I did before, and using nutrients. But also, maybe it may be a better idea to just water through and get a PPM reading again since it was so high in plant one.

Flush them. Water once to runoff, check PPMs of that runoff, adjust and feed next.
But to be clear, if you weren’t experiencing high PPMs, you would be correct, the flush counts as a watering, and you pick up feeding immediately after.
Good luck! And welcome to the forum!

If you water to runoff at every feeding, monitor the TDS of the runoff. When it rises above 1,500 ppm in soil, discontinue feeding and water only until TDS drops below that value. Then resume feeding. This eliminates having to do flushes.

While that is true for some (most?) nutrient lines, FF recommends a Sledgehammer flush about every 3 weeks, if you are using their line, which I use, and was making the assumption @BryanDavid was as well. I feed and flush by the schedule, and have found that I only need to check my PPMs if I see anything amiss.

So what you’re saying is flush with the proper dose of Foxfarm, and then add some additional plain ph correct water and check the runoff from that water, correct?

Apologize there’s a miss print in there. It should say plain water.

Anyway, I’m sure you understand the question. I’m just confused if you want me to water immediately after I applied the does the fox farm

I apologize for the confusing text. I was using voice text.

This is correct.
Welcome to the community 
No. I mean that after it dries from the flush, water once more, and check those PPMs. Then start feeding if the PPMs are down. If they are down, she won’t mind the short delay in nutes.

Plant #2 shows does not indicate need for a flush.
Of course they do. They manufacture and sell it. They also recommend starting nutes on seedlings even though their soil is advertised as good for 4 weeks or so.

Not a big fan, can you tell?)

I’m with you: FF nutes are very expensive to run. I’ll stick with Jack’s.

FF can be expensive @Newt I think he has it figured out at a minimal cost I’m sure of that.
Jacks for sure I’m not changing.

You don’t need anything but water to flush @BryanDavid …Sledehammer or Florakleen and any other popular flushes don’t do much more than water. I used to use florakleen before someone here advised me that it was a waste of money. When I grew soil, I drenched the plants slowly with a couple of gallons or more depending on pot size then checked runoff. If it was still too high I would drench them again a few hours later. Almost always…the second drench with water at 6.5 (which my well water is naturally) would bring the runoff in range. That’s just my personal experience with it. Good luck grow bro

@BryanDavid First grow myself. I literally just went through this on Tuesday. Noticed a browning in the cola leaves. Had 4100 ppm after 4 gallons of plain ph water. Had to walk away.
Asked for advice, told me to keep flushing otherwise it will stay high and never come down. It took 22 gallons over 5 hours to get the ppm back down to just over 900. 900-1200 is the target. Now I let it dry out and resume a regular nute schedule. I use FF as well but will now run enough water so the tray fills in the bottom and take readings. Then next feeding only PH water to runoff, then nutes, water, nutes, water. That was the advice I got. Hope this helps.
This is what I was looking at.

I’m not going to defend FF. A lot of nutrient lines work. I started using them, when I started growing, and have my process dialed in, and get great results with them. I was just trying to answer a question.

I’ve probably posted on here in excess of 100 times, you can have success with any of these. It’s just a matter of doing your research, trying, and correcting. I hate pretty much all of ff products, but could definitely make them work with some effort.
If you separate organic from synthetic and make a chart of ingredients for both lines from each manufacturer, they’re all pretty much using the same stuff. It just becomes a matter of needing 6 bags or bottles from one company vs more or less bags or bottles from another company. If there was as many google hits for learning how to apply fertilizers as there was “best nutrients for cannabis” half of them would be out of business in a year.

Exactly. Use up what you have and if you do more research and find another brand to your liking switch. I have enough FF prod for another grow then plan on trying Jacks and Coast of Maine soil, which everyone I follow seems to use.
