Nitrogen Deficiency?

So my plants are starting to get pretty bushy, and in the last couple days a fair number of leaves have yellowed and died. The leaves are all on the bottom of the plants and they are the more tucked away leaves on the plants, but the canopy is still perfectly healthy. I can't tell if this is normal leaf loss or nitrogen deficiency. They are currently in roots organic formula 707 soil, under 1000 watts of metal halide light, and I'm using house and garden soil nutrients. Any help would be much appreciated thanks!

Post your NPk ratios on the nutes you are using. It will help and say a lot. Are you high in p and k ?

^^^. Watch out. That is high in p for veg. But thats my opinion. a good ratio for veg is 3-1-2 or even a 1-1-1 and flower is a 1-3-2. Check this out. http://www.ces.ncsu.edu/depts/hort/consumer/quickref/fertilizer/nutri_def.html

I'm using House and Garden Soil A and B, Algae Extract, Drip Clean, Multi Zen, Root Excelerator, and Magic Green. Then also Mad Farmer Silica Shield, NUTS, and finally fish emulsion.

What are the NPK ratios on what you using. No idea what those names are. That seems like a lot of stuff to me.

The NPK ratio on the base nutrients is:
Soil A NPK Formula: 2.3-0-2.3
Soil B NPK Formula: 1-1.1-3.6


The two are added to the water in equal proportions.

commonly misdiagnosed as Nitrogen deficiency, it is Iron deficiency. when its N the yellowing starts on the outer edges, Iron starts from the vein.

They look pretty good to me. Just keep checking on the growth to see if your on the right track. But they look nice and green to me. Don't see any yellowing. I wouldn't be worried about what you lost. You will be fine. Just keep it up and try not to lose anymore.

i also say they look good. your nutrient deficiency can be resolved by using a well balanced liquid fertilizer. easy on the leaf removal. GL
