Low ph runoff coco

[Bubu_83]

Hello I am new this way, I have a problem with my plants. I am watering with ph 5.8-5.9 ec 1,7 in flowering and the 4,6 drainage is of ph ec 1.9. Use water of at least rested faucet 24h, the Coco a+b, the Coco to booster and the stimulator Coco bloom of b´cuzz. The water of my zone is of 384 ppm (0,6 ms/cm) ph I regulate it with ortofosfórico acid after adding the nutrients. I badly feel it by my English.

4.6 is for ph runoff?

some batches of coir have perfect runoff stability
some batches have very high (7+) but rare
some batches have very low (in the 4's) and is more common

this varies within batches from the same brand, and some brands are better, but even the really expensive brands put out bad batches

i have dealt with all three... very, very difficult to alter within the grow cycle... sometimes you can, but mostly not. although dangerous to use, hydrated lime has worked in the past, but it is touchy and the acidic coir fights you all the way through. would suggest transplanting if possible. if continuing to use coir, test each bag before you plant em.

If, 4,6 even 4 in some occasion.

The Coco I have used it without mixing nothing I have verified ph of the Coco that has exceeded to me (this without using) using a mixture of the Coco and distilled water to 1:1.5 and the 6,7 result is ph of and ec 0,1, I suppose that the Coco this good.

The plants are in their week 6 of flowering reason why I believe that it is not good for making a transplant.

Some idea?

Hi , your root zone ph is dropping because you are feeding too much ! 1,7 ec is very high, lower it down to 1,2 until your plants do better, then slowly work up from there.
ph of runoff should be more like 5,7-6,3 . Do a small flush with1-2 container size in volume of nutrient water with 1 EC ph 5.8-6 to flush out the built up salts, as your runoff EC of 1,9 means there's definitely salts being accumulated ! Then make new res 1-1.2EC and ph 5.8
Good luck!

The problem I see here is that to use 1.2 I can not use all products, ie I use a + b Bcuzz bloom stimulator (1 ml / liter) and Bloombastic (1ml/liter)

That ec would be advisable for each stage of the plant or week?

My tap water has a ec of 0.6ms/cm, then I have little margin for fertilizers. How do I do?

 

[Nifty_PoT]

hmm , well i don't know much about Bcuzz range but , i would leave the bloom stim and bloombastic for now , just use a+ b ideally with RO water to an EC of 1-1.2, even if you have to use tapwater lower ec to 1,2 (some other users might chime in with using hard water and Bcuzz as i only have experience with soft water).

Im assuming your plants aren't healthy ? so just lower the EC until plants look better however long that takes , runoff ph should then be higher... hard water isint a real nice thing to work with unless you know exactly whats in it.

 

[Bubu_83]

The plants show deficiencies are wrong, not if blockage or excess. At the moment I have no access to RO water, I'll do what you tell me aver as plants develop. tonight will try to upload some pictures so you can see how they are and need.

Thank you.

I still stick to this advice , looks like you have a nutrient lockout, due to salt accumulation . Flush till runoff ph/ec is what u put in the top (1,2ec/ph6). they should recover .

Flush for sure! Then feed less. Try to find a way to use better water. RO filters are not that expensive...

 

[Bubu_83]

Thanks for the tips. I'm going to do what they are advising me aver if they improve, which is the maximum I can use ec for the crop?

I have installed in a reverse osmosis home the problem is that a lot of water and I discard large water bills were coming, so I decided to use tap water.

Tomorrow are the flush and I will comment changes.

Greetings.
