AvT deficiency in flower, day 48

[Saosin]

Hey everyone, can you please help me out with this deficiency? It looks like phosphorus and/or nitrogen but I'm not sure. It is affecting some leaves on the bottom and some in the middle.

Medium is happy frog and ocean forest 50/50 mix. No extra nutrients are being given. Water is r/o and the ph is good as my other two autos (fantasmo and another AvT) are doing great with it.

This Avt is on day 48 and the growth is definitely slower than my other, which is only 1 day older. This seems to be too early in flower to start yellowing and there's some spotting on the leaves too.

The light is a 400w hps and temps are 79 to 81 max. Light cycle is 22/2. Humidity is very low. 20 to 25%

What kind of deficiency is this? Should I give some nutes? I usually just grow in soil with no extra nutes and they do well. Thank you all for the help.

...looks like mainly N defc., some of which is normal for this stage,...I'd start light feeds of bloom nutes, the soil isn't enough anymore, not to make fatter buds at least,.....

Okay, cool. Thanks. Do you have any good organic nutrients to recommend?

the cheap and easy (mostly) organic nutes is the liquid foxfarm stuff. You get what you pay for. They work, lots of people use them. If I were in soil, I'd go with Earth Juice (organic). There are so many brands. AFN has Remo on the site, kind of pricey.

The earth juice stuff looks good. I think I'll give it a try. Thanks for the suggestions.

General Organics is good too,...
