Rusty leaves, bacteria?

Looks like a P deficiency. Any blueish hue to the leaves? that would help confirm and easier to see with eye under normal lighting. Plant does look a little too lush, but i wouldn't starve the plant of a well-balanced diet. It may need less N when vege growth stops (i.e. leaves and stem growth), but it still needs a good chunk of it. Every nucleic acid needs N to be copied, otherwise cellular growth will be reduced. Ripening requires new cells and production of other molecules that involve N for sure. the over-simplified dogma that sorrounds "N" is often erroneous.

Hey mate, simple way to check if you nailed it down to those 2. Bacteria is like a socket on the leaf, so it makes the leaf a bit thicker. Its growing on there, u can more likely swipe it off. A leak of phosphor makes your leaf dry out. Drying out appears differently, leafs are thinner at those spots and crumble. They definetly leak a bit Phosphor, they overfed, its shown in the dark green color. So other nutrients lock out their phosphor intake. Lower your overall feed, For example i mix 50l like its 30l. So i take around 2/3 of the recommended amounts. Your plants also getting very tall, so i would suppercrop it, to even the height of buds. You could check my diaries i suppercrop a lot. To not break off any stems you simply have to press the part a bit together while snapping it. If you really break off something simply tape it back together and try again after 10days a few centimeter higher. Trust me, you will higher your yield by a lot. If you have any q, just PN me.👌

High Owopper, The deficiencies that you see here are not due a lack of any nutrient but are the problems cause by nutrient lockout due waaay too much nutrients and the wrong ones for sure! Stop giving any grow nutrients. Your plant doesn't need N anymore, it is craving for P, K and Calcium. Make sure to feed with the right pH value, between pH 6 and pH 6.5 for soil. Measure the EC, a cheap Chinese meter would do and cost around 20 dollars. The EC should never be higher then EC 2.0 and when you give the right nutrients EC 1.8 should be enough all the way till harvest. You want to water till 20% runoff to prevent nutrient salts building up inside the soil causing the EC to raise and the pH to swing. When you follow these rules your plant will reward you with big, fat, sticky, frosty and juicy buds! Happy Growing Buddy! 💚

Boost your mix to match a heavy flower period. Extra pk and less N..your leaves are very green..

Hey there man Great grow. I've had this same problem before. You just over did the nutrients don't worry I don't see it getting to much damage if you correct your problem. I suggest giving 50% what you have been giving I also suggest checking the run off water ph just to make sure the soil ph is not out of balance

Think phosphorus, some will say potassium ....
