Hi Im new to this forum and to growing, I have a few plants growing indoors and the past few days they seem to have come under attack. Any new leaves that come through are showing signs of something eating them, I have examined the plants for signs of spidermite but there is no evidence to suggest this is the problem. Can some body take a look at the pics I have attached and advise me please?
That looks like a nute burn rather than bugs.
Have you checked your PPMs and your PH?

I cant say one way or another. The first pic looks like bugs but if you cant find them then maybe it is nute burn. I see upon closer inspection your using coco. Let's talk about your schedule and see if it is nute burn or not. I grow in coco so I might be able to help there some and compare your schedule with mine. Take some different pictures and try and get them close to the damage for a better look.
For pure coco I water about every 3 days. The top of the coco should be pretty dry before the next watering. If you were to reach your hand deep you would find the pot still has water even though the top is dried out. The best way to water coco is by hand and pick up the pot before you water. You should be able to feel the difference real quick and pretty soon you will learn how to gauge your plants current moisture content.
For nutes I'm not picky. I use General Hydroponics Maxi Series which is a powder. I mix it with water to make a solution and then add that to my reservoir or to a bucket of water if your going to hand water. Either way the nutes and plant water should be mixed well together and then poured over the coco. Pour till you see about 10% run off and your good. I keep my PPM's at 800 for veg and 1400 for flowering. I work my way up to those numbers over the course of a week. The GH powders have ph buffers in them already so all I ever do is verify the ph is correct and usually whatever the number says I am happy with so I am good. Very low maintaince and prep, and pretty inexpensive.
Keep in mind that the leaves wont repair themselves. They may correct slightly but then they will eventually fall off. So to know what's what you need to be looking at the top growth for signs of problems or corrections.
Check the underside of your leaves with a loop of some sort. Mites are very hard to see. Check the top part of your media as well for larvae. Could be a moth just snuck in and did some damage. I found a giant locust in my the other day. I live in the city for crying out loud, where did a 3" grass hopper come from? I swear it was right out of the Bible or something. A plague of locusts (just 1) chilling on top of my best mom and chawing away on that bitch. I drop kicked that fucker so far away, only to rediscover him back in the room 20 minutes later. I tossed his sorry MJ eatin ass in the disposal and made that the end of it!
The second picture says it all. Those holes and the rough edges are not from bug bites. It happens when things go wrong...what specifically I forget! I have seen it before on my own plants. Seems like I have seen that during stressful times. Did you do something different recently?
Did you FIM them, top them or pinch them in anyway? I think that's where I have seen that before. Also, did you do anything weird with the lights such as put them into flower, take them out of flower and then put them back into flower again? Seems like the lower leaves are telling me that you did that at some point which is why the leaves are all stretched out and not even. Early sexing perhaps?
By the way, other then bugs and possible nutes issues, the other two possible causes will correct themselves in about a week when the new growth comes in.
