Are these signs anything to worry about?

Hello,

First time grower. I can't identify what's happening in these pics. I would appreciate any help or interpretation. Thanks in advance.

First, this is probably nothing but I've seen it on a few leaves here and there so I just want to know what it is.

The second looks like the leaf has been getting chewed on by something but it's the dead of winter in the northeast where I live. I can't imagine what could be devouring marijuana leaves this time of year.

The third leaf just shows discoloration and an odd shape.

These are all different plants but I have seen the symptoms on a few others. Are these something to worry about?

They look fine. Just don't over water. I let my plants dry out(not seedlings) even to the point of wilting. Some say it is too stressful but I feel it makes them grow a stronger root systems. I have a cheap H2o meter to probe the pots. The best system is the weight of the pot, just pick them up. I use fabric pots, vivosun work for me. What strains are you growing. What lights ? Good luck.

Ok thanks. I'm growing in Promix with Mycorrhizae so I don't think overwatering will be an issue as it is a very porous medium.

I'm growing Girl Scout Cookies, A-Train, and Apollo Haze.

I am also growing with Pro-Mix HP & mycorrhizae. I find that the stuff works very well.

While it is a pretty porous material, you still want the medium to be on the drier side before you give em water again. Roots need oxygen. A constantly wet medium can inhibit oxygen from getting into the medium and that could promote root rot.

With good pot drainage, I found that during the later veg and early flowering, watering was every 3rd day. Later in flowering, sometimes watering was a little over 2 days as the ladies appetites got a little bigger.

Yes. You can use it on it's own or use it mixed in with soil.

I have grown both ways - straight Pro-Mix and a 2:1 black earth/Pro-Mix blend. My preference is a 2:1 black earth/Pro-Mix blend.

so is it better than Mokoko I'm using that with no issues but I wanna switch it up a little and do a comparison

Hey @adrenalytic I think you should check for thrips, if the lower leaves look rusty it could be them. I also zoomed in on the 1st pic and it does look like possible thrip. The third pic looks like the rusty drying of the leaves. Check the undersides of the leaves.

I have not done any grows in coco so I can't provide any insight into whether Pro-Mix is a better medium in that regard.

I think price is where Pro-Mix is a little better. A 50L bag of Mokoko is about $25 and this year, Crappy Tire was selling the 3.8 cubic feet (107L) bags of Pro-Mix for $33.
