Hey guys 2nd grow and I obviously have a problem. These rust spots on my leaves, what are they? Initially I thought lock out, so I flushed for 3 days but that didn’t seem to fix it problem is getting worse. Affecting growth big time. Pics below of all 4 planted at the same time. Clearly see bud development on the problem plant is far behind the others. Any help is appreciated. Don’t think it’s a ph problem my ph is consistently between 5.8 & 6 (in coco). Big concern is fungus, don’t want the others to be affected if that’s the case, but would like to save her if possible.
It could be rust. But I assume it would have spread to the others by now if it was. If it was nutrient build up, you think flushing would have stopped it. Not made it worse.
I'd be leaning more toward a deficiency maybe, like low in calcium. Are you supplementing calmag?
Another option could be your water source. Maybe too much chlorine I the water, but not likely since the other plants are fine..
If you can help us out, let us know your particulars. Feeding schedule, nutrients used, supplementation used, rh, avg temps. Ect..
Feed daily half strength of recommended dose (autos). I do use tap water but let it sit 24+ hours before using. Using GH flora bloom nutes and calmag. Temps between 75-80. Humidity fluctuates a lot low of 45 high of 70 RH. South fla schizo weather so it throws me curve balls all the time.

by Nebula Haze Here's a series of pictures of a couple marijuana clones I had a few years ago. I was experimenting with growing an entire plant from clone to harvest in a solo cup, which is why you can see flowering plants in such small containers. Each of these were flowered as soon as the...
I'm thinking boron or phosphorus deficiency. If it's phosphorus then it's early, if it's boron then it's fairly well established. Could be a boron issue from not enough Ca or K. Possibly too much N. What is your runoff pH and ppm?
thats crazy if its Phosphorus because your bloom nutrients should have plenty of phosphorus. I will say its a possibility because you have the purpling stems, but the veins in the leaves would be purplish too if that was the case!
Just hit your plant up with cal mag then phosphorus and find out whose right! lmao
