Have a question about flushing and giving more nutes.

[Shawn Dotson]

I want to do a flush because I think there is some kind of lockout as my plant has seemed to stop growing and is getting lighter green at the top.

Anyhow... to the question.. I want to flush this baby out with a lot of water. what I need to know is should I flush with tons of water and then right after feed it? or do I add food to the water I intend to flush it with? If I can fert my flush also.. do I add enough for a single gallon feeding to say 5 gallons water or should the entire flush be fert at normal strength. This will amount to a lot more fert which seems to me would filter out of the water and over fert the plant. Still new to this and still hope to have a full successful grow some day. I don't want to burn my plant so I need to ask this even if it does sound odd.
So lets say I add 1 tsp per gallon and I want to flush 5 gallons.. should I use 5 tsp or just 1?
I know a real flush means just water but I only have 3 weeks flower left and I don't want to leave it without nutes during this important flower time.

A quik answer: Just water. Flush the soil, then reapply balanced nutrients.

Yes, good read. Unfortunately not what I was looking for. I am not flushing for harvest. I am flushing because my plant seems to have a stoppage of growth and yellowing. I am PHing so that good. Basically I am guessing on what it needs every time I water it so I might have went overboard and caused a lockout. Or maybe its because I added Epsom salt. I added a little of that because people said it helps plants take up nutes.

Yes but if I water first adding nutes will just flush through correct? I would have to wait for it dry out again meaning more stress on plant :/

you got pix of the plants in question? we could tell you this and that, but pix would definitely help us give you a better answer

Whats locked out? Why are you locked out? Is flushing the answer? Whats you feed program? Whats your ph? Your not giving people enough info. Just that your locked out with 3 weeks left and you want to flush.

Not sure what you mean... so, you over water today rights... flushing the soil... let it dry out pretty well.. which will take longer since in flushing you would up soaking the soil too... and then add either a top dress of something fast acting before your next watering, or you mix nutes (you know, balanced ones) to the water... if mixing into water add less nute than you think you need, to see if there's not still a build up of anything... even if top dressing, which is slower to spread the nutes down, start off slow

You're supposed to let the soil dry out a bit now and then anyway, and whatever stress you put on it will be better than the nute problems you're having, some people even recommend a little of that kind of stress, but that's a whole other topic

Yup.

I haven't done anything yet.

no, this is what you would do

Plant: Durban Poison (Sativa)
Veg: about 2 months
Flower 5 weeks
Nutes: Foxfarm crystals
Dirt: Mix Happy frog / FFOF
Feed chart. 1/8 tsp crystals and a few micros every other watering. (4 days apart except on hot days when I go 3)
PH: 6.2

Last 3 watering's I fed also because it looked a little light colored and was hungry. That was 3 days ago.

Also the yellowing in the middle of plant is because I had to transplant at 2 weeks because root were coming out of bottom of pot.

And your temps are a tad bit hight correct?

 

[Shawn Dotson]

It got up to about 95 for about 1 hour a few days ago. Was the only time that happened. (forgot to open tent) Other than that the temp never gets above 85. and no lower than 65. I run LEDS so don't get that hot.

3 LED panels 450-300-200 watts.. 2x mars hydro and 1 Chinese knockoff piece of crap.. but hey..its light.

I haven't read the entire thread but are you sure it isn't root bound?
I had that same problem... growth stopped and leaves began turning. Transplanting to a larger container did the trick.
good luck bro.

I transplanted at 2 weeks flower because of root bound in 5 gallon pot.. Don't really think it could be root bound again 3 weeks later in a 10 gallon pot...hmmm

 

[HarveyHarvester]

no, it won't be root bound in a 10 gallon pot.
I just don't know what else would stop growth like that.
cal-mag will most likely help the leaf color.
again, am a rookie.

I had a similar problem (on going) the water alone no super thrive or anything seems to be helping but I think I over mixed the fert

 

[MichiganMedGrower]

Yup.

I don't know you pot size or what potting mix your using which would be helpful for answers but I would run about 1.5 to 2 times the normal amount of water to get 20 % runoff. ( so twice the runoff. ) and then add a low 15 -25% dose of a balanced complete fertilizer in another gallon. Or whatever you use to get about 20% runoff.

I am guessing at but amount too because I don't know plant size or what you have them to burn the leaves.

But above is pretty standard practice. I don't think they need the advised 3 or 5 x the volume of the pot. This method has served me well with salt buildup.

It is called leaching. I don't know why we have all confused what flushing is.
