Extechs company website has it cheaper. I think its 99 was 10% when i looked 5to6 months ago. That ph meter is the ticket! Front row seat right there bud...BUY IT. You wont regret it. Keep the lens hydrated for it work right. If you notice it dry. Rehydrate it!!

Read the user manual on how to properly care for it and store it. Mine is a ph 100

That ph110 is a refillable one. I'd just stk with the ph100 not the 110 in that link

Been growing this girl a long time. Basically perfect leaves until recently. You can see in the pictures below the leaves have very recently gotten a yellow tinge. Anyone know what deficiency that might be?

Thanks!!!

This is a really bad forum to ask these types of growing questions. People will jump to conclusions without asking relevant questions.

As @TintEastwood already pointed out
Grow / tent size
Pot size
Medium
Nute mix
Nute usage
EC
PH
Lighting
Temp/humidy

We need to know all this info before ANYONE can even begin to help you.

From your photo it looks like this plant is in a pot somewhere in size between a solo cup and a 1 gallon pot and is in the 4th or 5th week of flower in soil. is this correct?

Whats refillable on the ph110? To keep the probe hydrated?

Go buy advanced nutrients revive. Clip those brown leaves off and you are good to go.

Seems like a lot of N for flowering... 15? not to mention the above from Tint... may be a combo.
