Well, followed @fnd suggestions and it went with NO problems, I used 3 gals,1 with the sledgehammer and 2 reg with PH6.5 I followed the bottle amounts …day later I flushed with 3 more. Got down to 3.3ph and around 845 tds, left it for a day and did a partial harvest on the chocolpoe and Bubba Kush,165gr wet/112gr trim for hash. Feed starts back up today till they all go amber on the trics, bout 10/15 days… then I’ll do it one more time and then the final harvest… some just needed more time for the effect I need. Thanks for asking!

I did not use sledgehammer before flipping to 12/12, ( prolly should have) only used sledgehammer before taking some of the parts that had All Cloudy Trics,( 2 gals w/sledgehammer and a gal of plain then 3 days of 3 gals a day to runoff) Chocolope and Bubba Kush are finishing first sooo I took the All cloudy and left the rest to go amber! Fed a full nute drench yesterday tomorrow will be the last I feed them… THEN… 2 gals of water with sledgehammer and a gal of plain then the rest of the week plain ol water.then I’ll take them out.:eyes:


So on the feeding schedule this is to be used between weeks 4 and 5. If I’m currently in a 1 gallon pot, I would mix the 2 tsp in a gallon of water. So, for the flush, would I spray the whole gallon of water into the soil within one day? Is that what it means by the flush? I just don’t want to overwater my plants, thank you for the clarification.

@latewood WHY DO I KEEP GETTING THIS BACKWARDS? I have been flushing my plants with sledgehammer FIRST! THEN using the ph water AFTER!

@latewood you really dont have to answer that. i know why i did it. dumb noob

On the topic of Sledgehammer-
I am in week eight in soil - turned to 12/12 two weeks ago - just got my hands on the Sledgehammer- what happens if I flush them now ? Do I just wait until then end - I know I should have flushed before flipping- first time grower - but what to do now - ?? Thanks for your knowledge.

Fox farms recommends a flush every 4 weeks. I just flushed Before switching to 12/12. I’m going to do it again once more at week 4 of flower.

I was really nervous to flush with sledgehammer but it worked out for me.

Check out my topic @Gkap

Also, for a quicker response, tag someone by typing an @ and then the name.

To Flush or not to flush (soil grow)

This is only you have been feeding nutes. If you’re in soil like ocean forest, you likely won’t be using nutes during veg so the flush cycles can be skipped until nutes are being added.


When I flushed my plants I mixed one gallon of the sledge watered slowly no runoff yet let it sit for about 10 15 mins then flushed another gallon of just water through and tested runoff to get ppm this is in a 3 gallon fabric pot too if ppm are where you want after second gallon no need for anymore but you can if it needs a ppm meter is a must though hope this helps I know sometimes people’s vague descriptions don’t help I’m the same need details almost need to see someone do it before I get it down

I just flushed my Bubble gum auto with sledgehammer, i’m in FFOF and FFHF soil using FF Trio. my plant is in a 5 gal fabric pot. I read a post by @Bobbydigital; flush with sledgehammer wait about an hour then flush with 4 gals of Ph’d water then the last gal give your nutes for the week you are in. My plant was in week 7 on FF feed schedule. Scroll up to @NeoGroR Jun 19 he has a link “To Flush or not to Flush” (soil grow) that will take you to @Bobbydigital post. Sorry about the round about way to get there LOL.

What PPM do you think is acceptable before cut? My last one was around 500. Maybe a bit lower. Smokes great. No notible crackling. Happy Frog but mostly Ocean Forest. Fox Farm Nutes as scheduled from Fox Farm. My Tap runs around 71 PPM.

Does anybody know what this Green thing is I’m not sure if it’s a banana or apart of the process also my pistils started turning red in week 4 seems a bit early

They still got a ways ago it’s normal to have a few reds early on @Ambitiousrj didn’t realize how old this post was sry
