“No special tools or techniques are required to flush cannabis plants. Instead of feeding plants nutrient solution, the grower simply feeds pure water or a light flushing solution. If you water by hand, then you can flush by hand. Similarly, if you use an automatic watering system, you can fill her up with pure water or flushing solution instead of the usual cocktail of nutes.”

No triple container volume bull fucking shit. Just water without nutes. Duh.

You should add Calmag at around 4 weeks, just before your bloom cycle.
Also, you cut off too many fan leaves, so you have no storage units left.
Don't do that again.
Also, always feed your plants during their entire grow, not just at bloom.
Just water until the soil is moist, and keep it that way, do not let it dry out.
Good luck
All good suggestions

I also wondered if I should be using any Cal-Mag?


Thank you for the reply. This may be a dumb question but I think it may answer my problem. I know there's no hard and fast answer but would you normally only give around 16oz of water to a plant in a 5gal pot? The reason I ask is because I've been giving around like 1.5gal of water which would explain a huge overwatering issue if thats the case.
Well man you’ve been over doing it on the water by a long shot....so watering at about 16oz will get you to realize that your plants don’t need to take a swim. It is easier for a plant to bounce back From under watering than over watering

He doesn't even use nutes hardly (a problem) so I don't even know why flushing (which is useless) is in his mind.
He should just stop hacking (de-foliate) his plants, feed lightly and all should be good.
It worked for me for 100 years :)

There’s another thread where the guy is in week 5 of flower and has never fed them. Beautiful plants too. His question regarded feeding them at this point. You don’t have to go nuts with the nutes to get good bud and a lot of it. Anytime a grower is trying to decide how to spend a little to get a lot more I always suggest lights, lights or lights.

And if you overdid something and flushing could help damn it is not worthless
It's like the cleanup at Chernobyl, once the soil is contaminated (over feeding usually) the only way too rectify is re-potting.
All the flushing in the world will not clean the soil or the root mass.
Damage will have been done, start again.
Sorry, but that's the way it works.

Your opinion. Then answer the question as to when you flush your ppm’s Come down. But I’m sure you’ve got some cockamamie story.? But I’m done debating over flushing on this cats thread

All your measuring is the water coming out at that moment, not what remains in the soil or the root system.
Do another test is 3 day's, and you'll be right back where you started from.
Simple solution, feed correctly with Ph'd water, and you won't need to flush

I've been using the same FFOF for almost a year now. Kinda half ass no-till. Just been top dressing with some Build A Soil Craft Blend, and reusing it. It does work better if they can sit and re-cook for a couple months though. I just finally started to mix some of my pots of it up and added pumice, lava rock, rice hulls, more EWC, and B.A.S. Craft Blend. I only use organics though and never ph the water. I love FFOF, but don't like that they then sell you chemicals that will kill your fresh organic soil. I guess it's a good way to make people keep buying their soil. I still have a bottle of Tiger Bloom that I bought for my outdoor garden years ago before I realized it wasn't organic. The Big Bloom though is supposed to be organic I think. I did notice that I started to have Magnesium deficiencies with the FFOF after a couple months, so I've also been giving them Cal-mag until my other stuff kicks in. Good luck man.

I apologize. I didn't mean to come in and stir the pot and leave. I do appreciate everyones help though. So my plan is to let the pot dry out just bit more continue gradually upping the nutrients +calmag along with giving way way less water, and hope I can salvage this plant the remainder of flowering. I do have other plants going so I have more chances to learn. I also had my roommate lock up the pruning scissors for the time being. Also need to do a better job of checking on my plants under light other than the grow light (I had no idea the plants had gotten that pale).

One thing I had forgotten about is that I had been using tap water and letting it sit out for a day before I used it. I had forgotten to set out water so this last watering I used RO water from the store, which also may have not been a very good idea (switching that is, not necessarily using RO). As I said before I don't have a PPM meter so I don't even have a way to measure whats in my tap. Going forward I think it'll be a good idea to get all that stuff in line instead of putting the cart before the horse.

One quick related question: Had this been in a DWC bucket/tote and I started seeing some weird deficiency or something I couldn't quite figure out, am I correct in thinking I could drain the bucket/tote and refill with fresh nutrient solution?

PSA - I swear I'm not out here purposely trying to mutilate or torture these apparently very resilient plants. I just have a black thumb.

I'll start off by saying this is my third grow and I obviously have no idea what I'm doing. This same situation has come up on all three of my grows so far and all at about the same time. I'll give some details about my grow first:

Soil: FFOF
Nutes: FF Trio (didn't feed any nutrients until about a week before flower)
Schedule: FF recommended schedule at 1/4 strength
Size of Pots: Started in 1gal pots and transplanted to 5gal smart pots after about 3 weeks in veg
Strain: Strawberry Cough
Stage of Growth: Just started week 5 of flower
Water pH: 6.5 going in but when I checked the runoff at this last watering it was at 5
Temp/Humidity: Daytime 78-80/30-40 Nighttime 72-74/30-40


So this problem has come up on every grow I've had so far (also, I was in a 2x4 tent before this one and that is part of the reason this plant is so small in this tent but doesn't explain the fact that it looks like Charlie Brown's Christmas tree). Everything seems to go really well until I get a few weeks in to flower. Then my leaves start turning slightly yellow and getting some brown spots. Seems like a potassium deficiency at first but yet I already have what seems to me like nute burn on the tips. I don't know even if it is a potassium deficiency, then will my regular nutrients be enough to get me back on track or would I need a K booster to help get it back on track?

Not knowing I went ahead and fed at 1/2 strength of what was recommended (I'm thinking bad idea now). Now this morning more leaves show even further advanced stages of the problem which makes me think maybe theres too much build up of something in the soil and maybe I need to flush? But I'm not completely positive what I need to do to flush either (is it just watering with plain pH'd water a few times?).

Sorry for the rant and thanks in advance for any help. If there's anymore information that I can provide I will do my best.
I'll give my 2 cents...firstly, as was mentioned...educate yourself on vpd and getting your environment in the comfort zone. If that's not correct, then transpiration is off, in which case, nothing else matters. Week 5 of flower, getting to the back end of mid flower now...you seem to have run into a phosphorus deficiency. Those leaves are dying as a result of not getting their share of P. You may also have/had, an issue with calcium lacking. Based on the fact that you have been feeding, and using a rich soil, one has to ask, why is the plant not getting it? Either you are overfeeding in general and causing an unhealthy environment at the root zone, or you're overwatering, or your ph is off. First thing to correct is the humidity..up it to 50% for lights on and could go slightly higher with lights off (like in nature). Adjust your watering and for that size plant in that container, in ideal conditions, should get about 2-2.5L every 3-4 days. I would also lower the ph closer to 6..and never above 6.3! On a side note, if ph drifts too high (near 7 or above), calcium will bond with phosphorus to form calcium phosphate, which is not soluble and can't be used by the plants. Those are the two elements in my opinion, the plant shows to be missing out on.

As for the ph coming out at 5...that could be a slight hint that you may have some build up of salts. It doesn't mean the ph at the roots, is 5, but it could be an indication that things are building up in your medium. Ph can also drop if there is calcium lacking in your medium, but generally the plant would look much worse if that was the cause of the drop.

My humidity is always low. I'm in Colorado and it's usually between 20-30% in my grow room. It's actually 17% right now. I know it should be a little higher, but they don't seem to mind. I kinda do having to water so often, and I'm sure they might grow a little faster with higher Rh, but the buds seem to appreciate the low Rh.

omgf whats wrong with u people reading thru all the comments jesus put the plant in a lab and test it lolol for 1 you are in soil with nutes 2 you are feeding them 3 foxfarm is packed full of salts and 4 you are putting ph water in soil lol i would say its got a mixture of lock out and nute burn peace
