Nitrogen Deficiency: Veg Schedule Accidentally Gave Flower Nutes

Hello fellow growers,

I've been using HGV nutrients for my cultivation, and I recently encountered some issues with my plants. About three weeks ago, I transplanted my cubes into cups. After the first week, I noticed that the plants seemed hungry, so I fed them with my nutrient mix.

However, over the course of these three weeks, I've observed stunted growth, droopy and yellowing leaves, even though the stalks remain green, and the roots continue to look healthy and grow. I suspected a drainage problem in my cups, which I addressed by letting them dry out.

However, I realized that the leaves were not recovering as expected, and upon further investigation, I discovered that I had been feeding my plants with 'Base + Flower' nutrients when I should have been using 'Base + Veg.' I switched to the correct nutrient mix on Sunday and have fed them once since then.

Now, my plants seem to be improving, but I want to ensure a faster recovery. Are there any additional steps or tips you can recommend to help them recover more quickly?

Below is what Nutes are in the formula.

HGV Growth Formula

• Total Nitrogen (N)......................3%
  • 3% Nitrate Nitrogen
• Available Phosphate (P2O5)............6%
• Soluble Potash (K2O)...................22%
• Magnesium (Mg)...............2.5%
• Boron (B)....................0.02%
• Iron (Fe)....................0.15%
  • 0.15% Chelated Iron
• Molybdenum (Mo)................0.008%

HGV Base Formula

• Total Nitrogen (N)...............14.5%
  • 14.5% Nitrate Nitrogen
• Calcium (Ca)...............19%

HGV Flowering Formula

• Available Phosphate (P2O5)............10%
• Soluble Potash (K2O)...................26%
• Magnesium (Mg)...............2.5%
• Boron (B)....................0.02%
• Iron (Fe)....................0.15%
  • 0.15% Chelated Iron
• Molybdenum (Mo)................0.008%

I'm glad you got it fixed, but the nutes weren't the issue.
There's not enough of a difference in the two 'B' parts to cause any issues, and certainly not the symptoms you described.
Using the flowering 'B' with the CalNitrate is still a perfectly reasonable NPK ratio for growing.

If that was the problem, all you need now is time and patience

At this point they're looking much better since we changed the nutes to what it is supposed to be. It was def showing signs of N deficiency. I mean, the biggest difference is 10% Phosphate vs 6% nitrate.

Correlation isn't causation.

It's all but impossible to have a Nitrogen deficiency using a CalNitrate 2 part mix, regardless of the second part formulation.

Your symptoms are consistent with a watering issue, not a Nitrogen deficiency.

The plants got better because you fixed the watering, not because you swapped the 'B' formula.

Hope so... Either way it's looking MUCH better now since we've witched the food and watered it one time.
