PPM with Organics?

[Overgrowtho]

When feeding plants with organic liquid ferts e.g. fish hydrolsolate or compost tea, is it a good idea to measure and dial in a PPM as done in hyroponics?

I noticed my compost tea came out to around 550 PPM and I am in flower which seemed a bit low? In that case, should I just add more compost and fish hydrosolate etc. to the tea perhaps? Should I mimic hydro PPM progressions?

Anyone?

The soil should be feeding the plant, with all the nutrients required. Don’t need to “feed” the plant with the compost teas etc. those are used more for boosting micro-organisms. My 2 cents

No.

Okay thanks for replies. Is it partly because the salt-based nutrients can be analyzed as such with TDS meter but the organic cannot?

No need to add additional nutrients with water because the nutrients are already in the soil. When going hydro you need to add nutrients because water has none, or with coco there’s not a lot of nutrients in the medium to feed plant. Organic soil, the nutrients are already present and the watering do not need to provide that in addition, the plant has what it needs in soil. Teas are still good IMO

Wouldnt you say that a blanket statement like this is over generalizing? Since organic soils can be composed in so many different ways and even run out of nutrients. A lot of them are sold as being able to support the plant through veg but not having enough nutrients for a strong bloom?

I’m growing organic and I add stuff that’s not in the soil already. You’re thinking of super soil.

Wouldn’t you just top dress with dry amendments/compost or recycle the foliage from previous run to add nutrition to soil? If using compost tea for immediate water soluble nutrients, isn’t that essentially a synthetic process in an organic system? When does it rain nutrients on plants organically?

I top dress with dry amendments and then just plain water. I use 3 things all organic. But I’m not using a “super soil”.

As far as adding foliage? You need a bin and some worms etc.

I’m not big on compost teas. I just use dry amendments and water. You just have to plan a few weeks ahead and allow the soil time to break down your amendments.

I would never add anything to finished compost tea because any little addition could change the microbe populations massively. Better to water in whatever you wanted to separately. In my opinion, as long the ppm isn't too low (ro water), there shouldn't be a need to adjust it.

I'm using organic super soil and also organic top dressing and adding teas and adding Biobiz liquid organic fert. First time so let's see how it goes. So far so good!

But is it normal to have 5-7 lower leaves turning yellow and falling off every day on the third week of flower?

Do you have pictures? Could be a deficiency of some sort.

It's natural that the plant drops the inner leaves closest to the stem about 4th week in flower, but like everything else it varies. Cheers!
