Can’t fucking figure this out

Also to clarify : I think many people who feed crazy in coco... like 2-6x a day are doing so in spurts until they get runoff. They aren't feeding until runoff each time. Plants need drybacks and when they water in spurts it stacks their EC

* I could be wrong tho I just do my thing & it seems to work :eyesmoke: :peace:

mate when I do water the bottom of my tent is FLODDED so I’m guessing I’m getting good run off I was even thinkin maybe it’s too flooded and the shit I’m flushing out with the flooding is getting back into pots and fuckin the more developed ones coz the roots are touchin it?
I keep my 5 liter fabric pots on stands so they don't touch. What is coming out is what you want away from your plants. If they are sitting in the runoff than they are taking in all those salts. I have seen some on here that don't water often, I just find if I feed them at least once a day and make sure to get rid of runoff they seem happier. Than again I don't profess to be an expert. It just works for me.

makes sense also I was thinking that maybe as the water is evaporating very slowly when lights off as it’s pretty fucking cold It could be that because I’m finding mold pretty often on the more juicier fatter buds

Mold is likely an issue with air flow. Are you in a tent? There should be negative pressure. As I say, I have 4 plants in 5 gallon pots in a 4x4 tent and if I don't feed them daily they get pissed. Cold is not great for them. Do you have a carbon filtered exhaust pulling air from your tents? What is your RH.

dunno rh broke hygrometer and yh I got negative pressure and 2 standing fans on full, I’m gonna find a way to collect run off and I’m going to leave my thermometer close to zips to a few hours into lights off ima check temps and yeah I’ve got a carbon filter removing air from the tent theducting is starting in the tent goin into a acoustic reducer then fan then filter and the door to the room with the tents is always open allowing everything to go into rest of house

Sounds like you got most of the issues covered bud. First thing I would do is get your plants on to stands. Anything will do, just get them off the ground so you are not sitting in runoff. If you need to collect runoff you can do a few things. There are may great ways, some diy self draining pot or just do what I do. Get a shop vac and suck it up. Under $50 and well worth it. Bud mold can be as simple as the roots rotting from sitting in runoff. Clearly you got most things sorted so it is likely some small over sight causing your issues. Get them pots off the ground, keep the air flowing and drain to runoff every day. I do that from seeds on up. If the pots are wet than it takes very little to get runoff. I like a 70/30 coco perlite mix, makes sure you always have 02 at the roots. I am sure a couple small tweaks can make the difference for you. Your plant looked great in veg, don't get frustrated, you can work this out.

yeah I’m gonna get some slats to put em on was thinking maybe I’ve reuse the same coco to many times I’m gonna try get some readings of the ec of the runoff, greatness is close I can feel it lol

Why did you allow them to get to this stage before chopping them early and saving what was then i assume good, 5 days between waterings means they are not taking up the nutes very well, so my guess is they just sat there and got fried due to stalling for whatever reason.
I grow in coco and reuse coco i don't bother flushing it out, i just go lean on first few feeds until plants show they want food.
Lastly i feed every other day and each week just feed plain water to prevent any nute build up.

Well guys after removing that plant I flushed the coco and checked the run off and it was flashing 3.6 on the ec meter so yeah was a build up of salts, I’ve since increased the amount I water em from 3 litres to my 18 litre pots to 4 litres and I’m going to do a feed of jus ph water every 3rd watering from now on. Do you guys know if this salt build up can cause a plant to hermie? I’m using 5 mothers but I’m killing one as on the last crop 2 of them hermied, they threw out bananas and even found couple seeds on the nearest plants to them. The strain is bubble runtz from tastebudz think they pretty new, the buds also don’t look really dense I dunno if they get denser in the coming weeks my other plants look dense asf

Try to water as soon as lights come on, any excess moisture should be gone in 12 hours. please don't let your medium get dried out, Good luck.

I would flush the pots rule of thumb is 10 times pot size which i believe is a bit much after much trail and error in the past but 3.6, maan that is high maybe do the ten times pot size flush plain tap water, then start feeding low upping until you get to where you want to be nutrient strength wise.

hi have you tried picking out that burnt bit on the bud?
because its hard to see but it could be bud rot
IF it is it will pick out easy.
if yes
1 teaspoon of bleach in a litre bottle of water pick out the offending area as clean as you can the spray around the edges

if it is bud rot it will ravage that cola in a couple of days

A full flush is 3X the pot volume with just tap water if that's all you have. If it's really shitty like 400ppm and pH 8 like mine then go buy some RO water forever so you don't screw up your next grow. Don't need to pH that but once that's done pour another part volume, more than needed to water the plant when dry but not a lot more, that is pH tested with 1/4 dose of normal nutes. That will push out the flush water and reset the root zone. Otherwise the plant is sitting there with nothing to eat until you can let it dry out so you can feed it something.

A full flush is the last resort. Things have gone FUBAR and it's your last attempt to save something you think is worth saving. Is it worth the effort? Might be easier to get some cuttings and let the momma go. Do better with her kids.

It takes forever to do too. 5gal pot x 3 is 2 hours of pouring water thru then getting rid of the runoff. Shop vac is handy for that but still have to dump that out a few times as well. If you can move the pots to a bathtub or a big rack with drainage then it's easier but still a PITA.

I use soilless ProMix HP with RO water and AN pH Perfect nutes and never have runoff or pH problems. Just the basic 3-part with Big Bud for my booster. Any old calmag will do and Epsom Salts are cheap like borscht! Works great for my DWC projects too.

Tip: A rolled up towel is great for getting runoff out of the catch tray. Just park an empty tray beside it and wring out the towel into it then put the towel back to suck up more if it's there. Then hang the towel up to dry in the grow room if you have low RH or take it out to dry elsewhere. I wash mine when it gets grubby but that's not often. Great for mopping up spills too.

:peace:

Okay so I’m my flowering tent plants go from looking like this at week 3 4
View attachment 4747747
To this a few weeks later

View attachment 4747749
My temps at lights on are between 25 to 28c

I don’t know humidity broke hygrometer


I’m using advanced nutrients as I’ve used the same coco about 3 times now and I flush it heavily before using again to get rid of any dust or general fuckery

I’ve noticed the coco isn’t really drying out as fast as it should IMO instead of being 2 3 days it’s dry at about day 5
could it be temps to cold at lights off?
Humidity issue?
I’ve tried flushing I’ve tried reducing temps with air conditioner it has a dehumidifier although I haven’t tried that
I don’t know if maybe it’s the old coco and it’s something to do with that and it’s only showing late in flowering because whatever fuckery is in there the roots haven’t grown into till late flowering

simply put I don’t have a fucking clue
Are you ph’ing the coco.I try to get mine under 6.2 coco under 6.8 soil but man you gotta maintain the humidity so de and humidifier u gotta get also check next nutes ppm before and catch a cup of drainage and ph and ppm it,it looks like it fox tailed but yield looks decent,

He is using coco. Do not flush coco with just tap water, it must have low ppm nutrients in it. It's because coco has a higher affinity at its cation exchange sites for Potassium and Sodium then for Magnesium and Calcium and running tap water alone through the medium will cause all of the Magnesium and Calcium that is associated with those cation exchange sites to be displaced by Potassium and Sodium.

I've learned in coco you have to water it every day (in flower at least), and that there is nothing wrong with watering in coco multiple times a day, it is just that with frequent fertigation you only add a little bit of water everytime and not really to any run-off.

I used to water every other day and I always ended up with huge salt buildups and nutrient burn half way through flower. The good thing about coco is it's oxygenation when wet. You can't really overwater coco because the medium has better oxygenation when it's wet.
