Can Anyone Tell Me What Is Wrong?

I noticed on some of the lower leaves on one of my White Rhino there are some spots on the top of the leaf. I have checked with the scope for mites(have none) I don`t have any other pests in or around my garden. This is only on a couple of the plants lower leaves. Any help would be greatly appreciated. I had this problem on my last run,some lower leaves would get these small spots on the tops. Only on certain plants,never all of them. All of them are in 3 gallon pots under 1 600 watt hps with temps getting no higher than 80 degrees F,and 50% rh. Good airflow under and around the plants. They are given distilled water and fox farm grow big for veg and tiger bloom for flowering(now in the 2nd week) Will be giving them guano tea starting this week. Keep It Green

i was going to say it wither dust or trichs, but there's also the browning/discoloration along the main veins - which is most likely linked? I don't know man.

How's your runoff pH?

I noticed on my white strains that they dump bottom leaves that look like crap, but the plant does fine. My Widows did a lot of that, I just ignored it and they quit it once they got a little bigger.

Now that I think about it,my last batch of WW did the same thing. Only the bottom leaves started to do that. Thanks for the insight

I will test runoff tomorrow when the lights are on(they just went off)

Let me know what it is, now I am curious.

I just got slammed with spider mites on day 47 of bloom.... son of a......

ouch...mites and its the hot season. That would suck about now. MR Neem Oil loves you though

I would say you have yourself a small case of potassium/manganese deficiency, as a result of pH lockout. Fix and adjust your pH levels and this should fix itself.

My second guess, without knowing your pH...is a magnesium deficiency. If this is the case, I'd take 1tbsp of Epsom salts and add to 1 gallon of RO water. I like to add the salt to a smaller amount (2 cups) of boiling water, so that it dissolves more completely (2-3) minutes at most), then add this mixture back to the rest of your gallon. Use this in your non-feeding waterings, and it should clear up.

It isn't nute burn, or that would be showing at the tips of your plants. And it isn't that you are over feeding or under feeding necessarily, but your pH is off, preventing the plant from accessing certain minerals/nutrients.
