Those look good nugachino, I do notice some yellowish in the leaves, is it hard to determine deficiency's with indoors and it looks like you have it under control

Cheers Pipenut.
It could look a whole lot better. I mean. About a month ago it was the tops that were yellowing. Now its the lower leaves...

I've done all kinds of shite wrong with this one. From too much water. Bad pH. To having to move it from a few different pots. And underwatering at one point.

They're all different in their tolerances. Some can be just about dropkicked around the room and not care. others will fall over the second you do something wrong.

Also. This one was bag seed. So. Guessing games were bound to happen.

Keeping plants in check comes a whole lot easier if you have an EC pen to keep an eye on TDS, ph, etc...
I'm going by the old analog water and dirt test strips and the like. Thinking it would be easier with the digital version... Just looking at my plants.

Nugachino is right. Even plants of the same strain can have different needs. Doesn't look bad especially for 90w cob. Did you switch to bloom nutes at switch to 12/12? Might explain early yellowing of lower leaves.

Definitely worth investing in ph and ec meter. Just gotta remember to keep them calibrated, that was my problem in the beginning of this grow lol. After got ph meter in check been pretty easy.

I just read that too somewhere recently that marijuana in particular is odd in that it can use the light spectrum produced by a HPS lamp for their entire life cycle.

All I know from experience is it is amazing for flowering.

With a SOG you can flower a dozen plants under a single 150w HPS. I wouldn't try to grow tree under one. Florescents are great for mothers and cloning. They can also work fine for flowering if you get the warm spectrum bulbs.

I don't know how big autoflower plants get though as I would never buy that monsanto-ish freak of nature stuff. But, maybe I'm a little out of place in this crazy world.

150w hps grows one auto quite well. start to finish.

I was wondering if I could grow 1 auto flower with a 150 watt HPS light. Any input will be greatly appreciated. Thanks

I grew this single plant under a 195 watt T-5ho fixture. Its not an auto flower but it just shows that yes you can grow successful with low wattage lighting if you are limited by space or lighting.
