nutrient burn or deficiency ?

[kenmastazz]

Hi,

one of my ladies is not happy and I can't figure out why

- Green Gelato Auto
- 36 days old from the seed popping
- greeleaf mega crop as recommended 4-5g per gallon
- tapwater 250ppm a lot of calcium very little magnesium
- tapwater + nutrients = 1000ppm
- cob lights 400watts
- humidity 50% temps 19-24° celsius
- ph 6.8
- biobizz light mix
- 9l pots

Im pretty sure is not over or underwatering its not my first grow so I have a little experience with weighing the pots etc.

thanks!

I run promix HP which is also peat based, and Mega Crop

I'd say add calmag to your feeding

Are you feeding every watering?
I feed every other day in my 1-3g pots, a d never any issues yet.i never plain water

I also don't see that it has ph buffers, are you pHing

I feed every watering and I don't ph after adding mega crop I get a ph of 6.8

I'd say add calmag

My friend uses her tap at like 200ppm and gas calmag issues

Add a full strength dose of calmag with the MC, bet it helps

every watering or once ?

Its hungry, but it could be a lockout. Feed PH? What is run off ppm (what ppm scale?) and PH? Do you let the grow medium dry out between watering or no? Id flush and start fresh with lower strength nutes for a little
