1/2 strength nutrients? need a diagnosis please

running half strength nutrients on this white widow.

I was running it at full strength but it started to show signs of nitrogen tox so I cut everything in half. now its looking like this, any suggestions on what it may be?

set up is as follows

DWC

2galons water flora 3 part
nutrients in this order


ArmorSI-2.5ml
Calmag-5ml
micro- 7.5ml
gro-7.5ml
bloom7.5ml
ph down to 6.0
ppm is about 420 right now.

thanks for any help

 

thanks for the reply Mac, I really should play closer attention to my PH levels as a hydro grower.

I PH the water down to 5.9 on Friday when I changed the nutrient solution. Just checked it right now and its solid 6.2

is this a bit high? and if it is can I just add PH down to the nutrient solution mix it up and add the plant back to it? or do I need to mix up an entire new batch of nutrient?

(growing in DWC)

 

Anybody care to weigh in on the PH?

I ph'd the water down to 5.9 on Friday when I changed the nutrient solution, its now at 6.2.

could this be the issue?

 

Thanks so much for the response!

Just checked Nutrient solution is as follows

PPM is 470
PH 6.2
temp- 19.5C/ 67.1F

i usually run PPM quite a bit lower than 470 so its weird to see something looking like a deficency? allthugh i could be wrong and maybe its not a def?

any ideas guys?

thanks so much again!

 

Thanks for the input,

Anyone have any ideas?

5.2PH seems rather low?

ive always aimed for 5.8-6.2, should I be aiming for a lower PH?

thanks everyone!

 

yah so my 5.8-6.2 would be pretty well right in the sweet spot correct?

 

Anyone have any ideas what could be causing the plant to look that way?

 

any ideas if this is a PH issue or a nutrient def anybody??
