Can anyone identify these leaf problems?

[Pvnuts]

Pic #1-- leaves are pale, does that indicate under nutritien?

Pic #2-- what does the black on this leaf tellin me?

Pic #3-- notice the tip of the leaf on the left. Is that too much nitrogen?

Pic #4-- in the middle some of the smaller leaves are curled.

what is your set up like? medium,nutrients,ppm,ph and water type? this will help with getting a better response but from just looking and seeing that the top of the plant thats right under the net you have a definite nutrient problem and the last picture on the corner bottom right looks like a pest on your leaves.

I'm using promix for my dirt. My water ph is always at about 5.8. I'm careful with nutrients cause I almost killed them all. I just started feeding them again two waters ago with 500ppm. I'm going to add another 500ppm on my next watering. At least that was the plan.

So I need to add more nutrients or less?

As for pests, what do you think I have?

You have alot of pests. Im guessing : gnats, thrips and spider mites for starters

500 ppm?? how old are those plants? and to me it looks like thrips on the leaves but pest in the medium can cause problems as well

My plants are about 4 months old.

My plants are about 4 months old.

yea now that you said they are 4 months old and only getting 500ppm that is pretty light ,thats about what i feed a 2 week old clone. Yea they are malnourished my friend wow 4 months they are screaming for more food , that is probably the leading cause to all your problems. This Is what i usually do everyone has different method but this works for me

@ .7 conversion
Rooted clone: 0-200ppm
1-2 weeks from clone : 200-500ppm
3-5 weeks from clone: 500-800ppm
Bloom week 1-4: 800-900ppm
bloom week 5-6 :900-1100
bloom week 7: 400ppm
bloom week 8:flush
if you have a strain longer then 8 weeks then i would jus stay around 900-1000 until you want to flower. NOTE every strain is different so you have to just watch it and be light because its easier to add sumthing but hard to take out
