Fixing nitrogen deficiency

Hi guys,
The plant has been growing quite fast then growth seems stunted.


i checked and PH was in good range so this seems like a nitrogen deficit.

My current nut feed has
1.22% potassium
1.7 calc
0.56 nitrogen
0.3 magnesium
0.4 sulfur

how should I fix this without getting surplus in other nutrients?

You're missing all of the micros. Its no wonder the plant is deficient. Feed it with a complete plant food, not amendment intended for use on the lawn. Cheers!

Sorry the missing info, of the feed also has
Phosphorus .05%
iron 80mg/kg
Manganese 20mg/kg
Zinc 22mg/kg
Sodium .55%

Magnesium nitrate would be my first choice. It's also good for stabilizing the nutrient solution. Do you measure the EC on the feeding solution?

It's probably not deficient if you feed them at recommended dosage. More common with nutrient lockout from overfeeding, every single feeding chart is to strong IMO. Hope that helps. Cheers!

Thank you for guiding me through this.

it’s a bit confusing to me when I basically fed nothing to the plant, only waters it to avoid nut burnt or overfeeding, then I started seeing the yellowing leaves so I started feeding with the recommended dose. However, the grow seems stunted (before feeding nut)
