Run off PPM

Curious if I should add some sledgehammer to my plain watering this week. Last nutrient feeding I gave my girls full strength week 3 flower fox farms feeding. PPMs going in were right around 2100, PPMs coming out were nearly 5k on one and about 4K on the rest. I see no signs of toxicity etc they seem happy and healthy but I don’t want that to change either. Run off ph was the same as water going in 6.3. I have the sledgehammer on hand and would just do a regular amount of water to 10-20% runoff. The tested run off was only 5-10% as I barely water to run off on mute feedings I have noticed early run off tends to have a higher ppm than if I check after it’s run off closer to 20. Thanks all.
 
I wouldn't flush until I saw issues, if it were me. I have never gotten consistent ppm runoffs when checking, some are more than I put in and some are less. I honestly feel checking runoff ppms is a quick way to gray hairs and being locked up in a mental ward. If no lockout appears I would say you are still fine. Just watch closely if a lockout starts to occur, then plan to flush it. But I think you are alright.
 
Do people usually go full strength with FF nutes? I go 3/4. Worry about burning them. I also use BeastieBloom too 1/4 tsp....
 
Locrian99 and I were having a discussion on another post about feeding full strength level nutes and what plants can handle or not. This is the first time he has fed this high he was experimenting. We are guinea pigging some of our girls.
 
It’s strain dependent. I just bumped those plants up. I have two AI I’m only giving half strength to. I too am giving 1/4 tsp of the boosters.
 
Little background on the discussion basically I started at 1/2 strength and am watching what they can handle without burn. Nebula has info on the Wonder Woman strain on the site and mentioned giving them full strength so I’ve been bumping them up in increments. The Girl Scout cookies are along for the ride. Basic idea when I see burn I’ll go back to the previous level. I’ve seen no burn yet. Just the PPM had me worried. I’d do a bit of research on your particularvstrain to see what people have had success with. I’ve looked around at various grow journals on several sites on these strains to get an idea of what people have had success with. And as urbz said kind of Guinea pigging it. I’m prepared to dial it back if needed.
 
Nutrient companies are in the business of selling nutrients so their feed schedules are going to be a bit heavy. At the same time they aren’t going to tell you to give so much it’ll damage them unless the strain in sensitive, because you probably won’t be using them anymore if that’s the case. At least that’s my thoughts. I’m also in soil and do a feed/water/feed/water schedule and only water every 4-5 days so they are only getting nutes every 8-10 days with a plain water to about 20% runoff between.
 
Hey 99, when you use nutrients, that's the only way to tell ,if they are getting to much, is by tip burn, I always, especially when they are a little older an growing good, feed until I see tip burn. Then back off the nutrients. I want them to get maximum feed, and I sure wouldn't be flushing if there is no problems, cause you can sure cause all kinds of problems with flushing, besides it being hard on your plants.
Good Luck, I'm sure your gonna do just fine.
 
Those are my literall exact thoughts as well. They are paid to make nutes and their feeding regiments. So they have to grow plants to test... If they had dying plants everywhere I doubt they would sell and suggest you do the samething. They would never make any money. Every customer would be 1 and done. Word of mouth happens fast enough now a days that would critically damage a company and their sales.
 
Just to be clear I wasn’t going to do the traditional flush just give them a flushing agent. I believe it’s yucca extract in the sledgehammer and give them the regular amount of water. But I’ll hold off, mainly I don’t want to end up thinking it’s nute burn and it be from salt build up. I think urbz is probably right and I should just put the damn tds meter away. Lol
