Can you guys take a look at my plants and let me know what you think about them?

I am growing with a soil that is seemingly extremely clumpy. Drainage appears to be an issue, and I only need to water once a week at best but they still appear overwatered.

What do you guys think? Is it also possible to improve drainage mid-grow?

They have all been in veg for about a month now, and the shortest is about 10" tall and the tallest around 19". I'm growing 6 total - 3x master kush, 1 dinafem powerkush, 1 dinafem moby dick, and 1 G13 Pineapple Express.

I've fed them twice now with FF big bloom and grow big at about 1/2 strength.

+ REP for any help :blsmoke:

The fourth pic, of the PowerKush appears the worst.

I have noticed some small black gnats (?), what kind of damage could they do?

They Could Be Spider mites and you dont want those, they can hurt ur plant and suck out shit that the plants need. take a magnifine glass to it and if they are clawling around you might have mites. you might have to spray ur plants down.

You definitely have a N deficiency, but I'm not positive that it's the cause of those really bad, spotted leaves. I haven't read up on severe N deficiencies lately, so necrosis could be one of the more severe symptoms. Could be magnesium too, as those problems sometimes start mid-plant. Either way, they need some veg nutes, including some mag. You're soil doesn't look too bad, i see some perlite in there so the drainage shouldn't be too terrible. How's the temps? If they're in the lower 70's that would cause the soil to take awhile to dry out, as would a lack of a good fan blowing on them. As for the deficiencies...either the roots are drowning, the PH is off, or they simply need more food. I think you're best bet would be to start foliar feeding until you get to the bottom of the problem. :)

Thank you for your help.

I added a decent oscillating fan into the tent last night (all I had was a little non-oscillating fan for movement), and now have my vent fan running 24/7 instead of just when the lights were on.

I also fed the plants yesterday, but only did a light watering as I was scared to do much more (I had waited 8 days).

Also foliar fed this morning Big Bloom and Grow Big according to the instructions on the side of the bottle.

Fingers are crossed!

Spider mites don't fly though right? These appear to just be your typical black gnats, and not many of them. Will probably try this method to get rid of them:

Step #1
Get a small glass or mug (clear seems to catch more i have no idea why!!)
Step #2
Pour some vinegar (apple cider vinegar I use) into the mug about 1/3 full is good maybe a little less.
Step #3
Drop a few drops of dishsoap into the mug (to add a little zest )
Step #4
Put the mug into the area with the most gnats (you can put mugs/glasses in different rooms if they are in those as well)
Step #5
Let the mug do its magic
