we need a lot more info to figure out your problems...
What kind of ferts are you feeding and how often ?
Are you feeding to run-off ?
What's the input pH of the nutrient ?
What's the run-off pH ?
What is your water source ?
If you're using bottled water, what's the label say (crystal springs drinking water, distilled water etc) ?

i just noticed that i was feeding them the past 2 weeks with ph of 5.2, i just now bumped it up to 5.8-6.2.

PH IN SOLUTION: 5.8
PPM OF sOLUTIoN: ~600

Nutrient solution is:
7ml of Canna A+B
6ml of Hygrozyme
5ml of molasses

PH of Runoff: 7.0


why is my ph of the runoff higher? doesnt make any sense to me. thanks!

im feeding to run off, using tap water with ppm of ~100.

heres a recent pic of her, all of her bottom leaves are dying!!!

Is that nute the Canna for coco ?
Are you feeding daily ?

pH of run-off 7.0... what brand of coco are you running ?

btw, what method are you using to measure the pH ?

 

[bombdotcom]

im using the General hydroponics tester where you just drop 3 drops into the vial of water and it changes it.

yes its the canna nutes for coco, my plant was looking great 3 weeks ago andits slowly started to degrade

im using botanicare cocogro bricks. My plants have been thriving for atelast a month or two.

Are you feeding daily ?

Sure looks hungry, possibly a salts build-up in the medium.
leech the coco thoroughly and follow it up with an immediate feeding and drop the hygrozyme.
Coco should be fed daily to a good amount of (10% or more) run-off to carry away excess salts.
If you were alternating feedings with straight water, this is why she looks so damn hungry.

i feed her nutrients every day, i never give her straight water...i also make sure the runoff is anyhwere from 20-40%

why is the ph of the run off so high?
