New Grower First Grow - 4 Different Auto Strains in Coco

I'm probably just paranoid. It just looked a little lighter than the day prior.

Just because you're paranoid doesn't mean they are not after you .

You are doing the right thing, never be afraid to post a picture you think may show the beginnings of a problem. It is always easier to repair something caught early.

Believe me, Exivious, you will know when something isn't wrong. You are probably just expecting it because it is your first grow, but you could be one of the lucky ones who gets through a smooth first grow. Being attentive is important, though.

...And here we are, my first real problem perhaps.

Day 12:

I didn't notice this around noon at feeding time and I'm fairly certain it wasn't there, but 6 hours later, the colorless dots were quite noticeable with the full-spectrum grow lights on. They're a little more subtle with a 4100k CFL (as pictured above).

It's most apparent on Forum Stomper (pictured above), though is noticeable on White Crack as well. Sour Crack and Fugue State are younger by 2 and 5 days respectively.

Theory 1: I was a little messy with watering. Droplets left on the leaves could have burned on contact. I mean, I hope that is what happened as that would represent the epitome of 'superficial damage'.
Theory 2: I upped P/K earlier today. I'm still well under GH's grow schedule.
Theory 3: I'm now off to look at deficiencies/toxicities to try to figure out what's more likely.

Doesn't look like powdery mildew. There are definitely no bugs in the tent.

More pictures please. Do you have a lupe or strong magnifier. You need to look under the leaf for insects (mites).

Here's the best pic I managed:

So much for 'colorless'... As you can see, it's sort of brown or coppery actually. I looked under every leaf and the whole tent seems sterile, save for the four plants.

What's interesting is the spotting is all toward the center of the leaf which is where it sort of 'cups' water droplets from feeding splash. Maybe I'm grasping at straws though.

Edit: Actually, here's a little near a tip:

Could this be really early septoria? I don't see any dark spot in the center, though.

I'm going to make an infirmary post.

Another spot I just found:

Could this actually be early stage calcium deficiency? I decreased CalMag a few days ago by 40%.

Oh please let this be it. I will raise CalMag immediately.

Why did you lower calmag?

There was some logic behind it, however misguided. I first started reading about growing just two days before biting the bullet and ordering all my supplies (about five days before germinating). My baseline early on became the ultra-conservative growweedeasy guides. They recommend a lot of traditional stuff like 'only feed nutrients every other watering' for coco. I thought since I was feeding daily, perhaps I would back off the usual CalMag dose just a little to avoid an accumulation of calcium toward the end of the grow. It would appear it might not accumulate in the substrate to the extent I had anticipated.

I'm about 95% sure this is the problem now. I'm going to do a light late feeding tonight to bolster calcium levels.

Edit: I just re-fed, this time with a hefty dose of CaliMagic. Day 10 is when I decreased from 5 mL to 3 mL.

Yesterday evening, Day 11, was when something just seemed wrong about the color of the older leaves to me (~30 hours after the first reduced CalMag feeding).There's something to seeing it in person, I think, which allowed me to intuit something was up before it became readily apparent in photos. This has been a valuable lesson, and I hope one that won't stunt growth and hurt my final yields too much.

You sir are thorough and detailed. I'm jealous.

Hahah thank you... I can drive myself crazy sometimes, or get myself into trouble over-thinking something (like calcium dosing), but hopefully it's a net positive.
