Nutrient Deficiency week6 ideas?

Can someone throw me some ideas. Or am
I crazy? I’ve had this yellowing on one plant since the beginning. I posted previously some people said it was probably new growth. PH has not been over 6.1 or under 5.6 the entire time. Ppm1450 on week 6. I just flipped the light over this week Bc i wanted to veg a little more. The yellow ish plant is smaller but thicker and bushier. They are different stains.

Really hard to say. It could be an iron deficiency, but I’ve never seen it it such a young plant.

A support ticket will help.

Hello @Dcmem we could use a support ticket to better analyze your situation.
But in the meantime try this for some self help.
Take a look and ILGM plant care

Make sure your environment is running efficiently.

From your post I’d say 1450ppm is too high. Even though the plant food manufacturer states a recommended level at maximum efficiency, are you at maximum efficiency on your; lighting, temperature, humidity, air circulation, air replacement, oxygen to your roots, etc,…

What nutrients do you use? 1450 ppm does seem quite high for your plants as they still look pretty young.

Do you use the well water for your nutrients or do you get ro or distilled water from somewhere else?

I used spring water originally then tap the last two changes. Using fox farm big bloom grow big

So how much cal mag should i be using? Or will using well water fix that?

Man i personally would use that well if it tests ok. No human added chemicals besides farm runoff. I love well and pond water. None where I am now…sux.

I have a couple 20 gallon catchments that I utilize, when they don’t run dry. Otherwise tap water at about 270ppm. I run them all through an aquarium multi-stage carbon filler to keep it the girl happy.
Fluval 07 Series Performance Canister Filter for Aquariums
All the while I chill the filtering water down to about 68 with some frozen 2 liter cola bottles of H2O.

Do you know your ppm of you water right out the tap? If it’s over 120ppm it’s considered hard water and might want to look into some nutrients specifically for hard water, especially if your ppms are closer to 200. Looking like it’s a magnesium deficiency with yellow on the veins and stunted growth. I would flush your plants with something like florakleen from GH to help break down all the salt build up then introduce the nutrients back at half strength maybe even less and watch your numbers to make sure they’re eating/drinking properly.
