Help with ppm

[Slothman]

I have a plant see (journal), and it's late flower I've been keeping the nutes pretty high but I noticed it was showing nute burn so I lowered the ppm and it's now down to 550 do plants need less nutes in late flower I thought they can handle more

it totally depends on your local conditions... if you have big lights, you will have big nutrition needs, small lights, less needs.

It depends how late in flower and a bunch of other factors. I often drop down to low feeding levels like that for the last couple weeks when I’m waiting for them to finish. Not much info to work with here....

I'm at work right now when I get home I'll update the post with pictures and more detailed info.

Plus depends on what yer feeding then

Meaning N P K %

Ratios do need to change in flower for sure

Hey Sloth, I’m sure you’ve got it covered already but make sure you know which ppm scale your pen tests vs. the scale the nutes feedchart based on. Pens vary between ppm 500/700 and so do nutrient brands, so if you’re not aligned it can result in over/ underfeeding. This is why I always go by EC instead of PPM.

Here’s some common brands and the scale they use just for reference.

I'm using cyco and I believe they use the 700 scale they're saying I should have it at 1650 ppm that seems high

Also my plant is doing this thing where the leaves are like crunching together
