It’s hard to say without seeing the entire plant and knowing more about your feeding and soil. But if they’re a decent age, then a little yellowing of a leaf or a dead tip isn’t really anything to worry about. If they’re young(less than a few weeks) and that’s happening, then I’d say it’s a nutrient deficiency. If that’s that case then it’d be hard to say which it is and whether it’s too much or too little. But they honestly look totally fine to me. Nice job!
@Kushrules Can you show more pics of the entire plant? And how old are they? And are you feeding them any nutes?
First 2 looks like a bit of nute burn, third looks like possible pests.
Does this look like a bug to anyone else?
Holy crap, Inspector Gadget. Yeah it kind of does. Now I have to get my reading glasses to look at those pictures again.
I agree with @Hellraiser your last picture has a few mites on there. Spider mites possibly so I would isolate completely. I’ve had these and used predators to get rid of the infestation but it was a nightmare. If you’re keeping it then attend to your main grow first then deal with that one as they will hitch a ride on you to get somewhere else. Spider mites, if that’s what the are, reproduce every 3 days so be ultra careful
The one on the right, waiting for lights to come back on got better pics
Using Vermisoil
Molasses, & cal-gro i think it is
Clones…i got them 2-3 weeks ago
Im assuming they were about 3-4 weeks old, guy i bought them from thinks i f***** his girl so he gave me a hard time & wouldn’t tell me much about them smh
Also, wouldn’t tell me which nutrients to buy/use
I got some money to burn, anyone down to help me ?
We can help no problem. I use Bio Novo nutes just now, a lot of folks here use AN nutes. Have a look around the forum for nutes there will be loads on here. Depends what part of the world you’re in as well as to what’s available and where. Have a look on here for light cycles for veg and flower. All the information you need is here just have a rummage through this forum and if your not sure ask.
Look for light cycles
Grow medium
PH and PPM
Nutrients
Lighting to name but a few. Happy hunting
