Neut burn?

[Pleb Scrubber]

Thanks for the detailed feedback.

Im using the merlin-method to flush right now.

 

iatd:

I have been using the EC as a guide to how much water or neuts the plants are using rather than the PH.

Could be a mistake?

 

The PH tends to slowly creep up, when it hits 6.2 I knock it down to 5.8 again.

 

I will try a little lower as suggested... 5.6 assuming that it will keep creeping up.

 

 

-----------------------

update:

 

First flush brought the PH from 5.9 up to 6.5

and EC/PPM from 188 to 235...

 

Dumping/Flushing again...

Hey pleb. I used to do it that way until my uncle told me about using ph to gauge it. I like to let my ph rise also, and bump it back down. It usually takes my 150 lt res a week to go from 5.5 to 6.1 ish. I havn't had any problems with over fert this grow.

I may not have explained my neut readings properly earlier... as I was just telling you the reading of the res including neuts and the water.

 

My tap water, before adding anything is around 0.4 EC, so when I said 2.2, I should of said 1.8(neut strength minus water)

 

2.1 was the neut strength where it started to burn.

 

I have flushed 3 times and started them back on 1.8 again, dropped the PH to 5.6 this time.

 

Thanks for your help.

Aint no expert, but im pretty sure you still take the EC of the tap water into account, and you dont really want to go above 2. I think...

[Pleb Scrubber]

ok

 

Ive been following the neut calculator on the ducthmaster site.

They say their numbers are based on pure 0.0ec water, and to adjust accordingly?

an extra 0.4 makes a huge difference...

 

Once I get enough rainwater, ill be using that which has an ec of less than 0.1

Another tip I heard the other night from a legendary grower is water out of your AC... Usually has a pH of 7 and EC of 0 apparently..
