Having some problems with a few plants in the group. Any help would be much appreciated. In most of the pictures you can see that something looks like it's been eating the fan leaves. We also have some deficiencies going on as well. So any help there would be great too. I put two of the same strain there together so you could see the discoloration between the healthy and the not so much regarding the deficiency. Thanks.

Sorry they're not great, all I had was the iphone. Pic's 6 - 11 seem to show the areas I'm worried about regarding the bugs the most. You can see the deficiency problems throughout. Using Fox Farm and Botincare CNS nutes, PH stays around 5.9-6.0.

On pic 5.jpg and pic 11.jpg I see light green speckles. Is there spider mites underneath those leaves. Also brown leaf tips indicate fertilizer burn might be caused by organic fertilizer reacting to hot weather. Organic fertilizer breaks down faster with heat.

For fertilizer burn use water without adding nutrients and for more severe cases flush clean water through pot. For spider mites use insectical soap such as Neem oil, azamax, floramite depending on what your mites are immune to already.
Mighty Wash? 91% isopropyl alcohol(very flammable - lights out for 5 minutes) in mist sprayer?
I don't know the effectiveness of the last 2 but I think isopropyl alcohol may produce quick results.

Hey AdvancedUser, thanks for the response. This batch of clones did come with some mites from the dispensary, they were quarantined and treated with azamax. But those were not what I was concerned with, in pic's 5.jpeg & 10.jpeg if you look to the left of the leaves with the little white dots (earlier mite damage) the middle leaf looks as though something's been chewing on the outside of the leafs. Thanks for the info on the fertilizer burn as well, I'll look into that.

look under the leaves with the brown spots is there brownish grey stuff caked on there. Might be a fungus. google search botrytis blight and phoma cannabis. Best to remove damaged leaves and spray entire plant with fungicide. Stop misting leaves, spores are spread from splashed water from infected leaves. When plant is healthier keep a lookout for the brown spots/grey-brown underneath and whenever you remove infected leaf, flame sterilize your blade or scissors with your lighter.
