salts in soil?

[Guest]

Hi, thinking about using canna nutrients just wondering about salts in the soil and flushing

I always used bottled organic nutrients so I never worried about flushing but now I want to try chemical, canna nutes


I will be feeding once every week or two, I understand the nutrient salts buildup in the soil? How often is a flush needed? What exactly do I do to flush? Would a product like Botanicare Clearex work? How would I use it?

How do you guys usually adjust your pH with nutrients like canna? And to what pH? 6-7 ?

well 6.5 6.8 is ideal and to flush means to water with plain r/o or bottled water at least 2x times your normal watering amount to flush the extra salt/chem left in the soil. and i belive you just adjust the PH with water i belive.

Does flushing pose any problems? How often do you do it?

How do you adjust the pH with water that makes no sense at all.

It is impossible to fully flush soil substrates,, because excess nutrients fix themselves to soil micro-organism under hydromorphic conditions. It is only ever possible to slowly leach a soil substrate of nutrients over a period of time.

water has a pH level,, acidic or alkaline. By adding pH-up or pH-down the pH of a water/feed can be corrected to suit cannabis plants.

likewise water pH is always relative to the soil pH,, :wink:

hope this helps

So are you saying flush once a month? So it's a regular flush?

I just recently had a problem due to pH down salts, is it because I didn't flush? It happened within 30 days of using the ph down salts, is this normal?

No. I's saying why bother 'flushing' at all?
The result doesn't justify the action,, soil substrates cannot be 'flushed' fully and the swamping effect causes water-logging.

IMO forget about 'the flush',, just aim to purge plants of nutrients during the last few weeks of bloom by feeding them a water diet only.

It is extremely difficult to 'judge' the pH of a soil substrate since component parts (sods of soil) hold their own relative pH,,, the run-off water can be measured,, but again this only records the pH of the parts of the substrate that is leached,, but doesn't actual give an accurate reading over the pH of the soil per se.

Applications of water correct themselves to the pH value of the soil,, not the other way round... since soil is a living organism itself. (e.g. feeding heavy acidic soil with alkaline water alone,, will not balance the substrate). A concentration of high alkaline organic feed on the other-hand, will alter the relative pH of the soil given time. Outdoors growers add chalk or lime to the substrate to balance pH.

IMO forget about soil pH,, just aim to use a soil-base that has the correct pH for cannabis from the start!!

but if you dont flush somewhat then you will build up ferts as well as salts and yes that can be a problem...... But its your grow. the key is to get all the chems and such out of the soil, but not alwaysgets them all. its like changing a dirty dyper. if you dont it will get worse and worse same with soil. of course tho ur not going to get all of them but my point is that u can flush every month or 2 weeks depending on how much ferts/chem you use and if your plant shows burnt leaves from over fert/chem.

 

[Guest]

Yeah I thought you needed to flush?

Little confused Leaf... the salts build up in the soil over time... you need to flush.

Even just recently just using pH down salts with every watering I caused salt buildup and burn to my plant, in 1 month that happened. I imagine it'd also happen using nutrients.


So would it be better to flush with water or a product like clearex? I imagine a product like clearex would do a better job flushing

incresing the chance of root rot and fungus.

this is what happens as a result of over-watering.

Does there appear to be more than a bit of mis-information here? How can you "FLUSH" every couple of weeks? The medium will fall short of drying out between getting Douche Jobs let alone being fed. When Humans ingest to much water they risk the chance of "flushing" away their systems Electrolytes.

A study of "Leaching" and "Flushing" would be in order, and for the beginners another reference point for healthy plant growth.

not true i just did a flus on my plants and i waterd w/ ferts for 3 weeks and then let the soil get pretty dry and then flushed with plain R/O water and my plants look very happy and thats only after 24hrs. so yes flushing is very inportant i would use just plain water to do it tho. the purpose of flushing is to try and get ride of build up nit add a chem to help flush. after you do flush wait till ur pots need water and then start ur regament again. hope i was of help

The onliest thing flushed in my house is my terlet.And my face when I accidently hit those girly links.

Ooops too much time denside..If you're having to flush excess salts from your medium you're using too much chemical ferts,you'd be better off using less and not flushing the soil.I use fox farm and PBP and never flush,the idea is to keep the correct amount of nutrients in the soil,not to flush them away.Towards the end of flower I'll use R/O water only to try and use up the last available nutes,its a balancing act.Even using chemical ferts you dont want to flush midway and start over,you want to use the minimum amount for optimum growth.Too much salts equals too much fertilizer.

Well said we agree

peace all

 

[Mrpiston38]

2 each there own thats all I am going to say

 

[DocLeaf]

With a free-draining medium like coco, that holds no nutrient value,, then sure it is common practise to feed and flood/flush the medium many times during the growing and flowering cycles

Some strains like to be flooded and drained/dried,,, before being flooded again.

But using the above method in soil, wouldn't/doesn't require feeding or watering in between, so salt build-up should never occur.

hope this helps
