Doesn't seem too extreme, and is only isolated to one strain and a handful of plants, but I want to catch it early and I'm not quite sure what this is.
Had a somewhat problematic veg cycle in my current garden, which was corrected a couple of weeks before I flipped. Now, 31 days into flower, I go into my garden today, and when I put on my "correcting" sunglasses, right away I noticed a problem on a small amount of the foliage, seemingly only on one strain, on a handful of plants. Maybe 3 or 4 plants out of 14 Qrazy Train plants. Brownish coloring/blotches seeming to begin at the edge of the foliage, working but staying between the veins at first, and hasn't overtaken all the way through the main middle vein of the leaf. The most affected leaves curl because of it in the spots where the edges of the leaf has "died off". Doesn't seem to overtake all the way to
Due to seemingly "hot" soil throughout veg, I didn't start feeding until I believe 16 days into flower. I've been feeding fairly lightly, no more than 1/2 strength.
I've been alternating water/feed, and yesterday was only going to be fresh pH'd water but I gave them 6ml/gal of Sweet Raw. Basically the only thing I've done different, as I haven't included Sweet Raw up until now. The previous feeding/watering was 5ml/gal PBP Bloom, 2ml/gal Hydroplex, 3ml/gal ProTekt, 3ml/gal CalMag+ I believe.
So, my theory is that they've depleted a lot of the nutrients remaining in the soilless medium (Sunshine Advanced #4 amended with organic dry nutes), and since I've been feeding light, they are just hungry. Being 31 days into flower, every strain in the garden has been looking great thus far - really starting to swell now and packing on the resin.
Anyways, on to the pics. In the HPS glare with correcting sunglasses on, this looked VERY prominent, dark brown almost black. In natural light it isn't nearly as prominent, roughly the same color just more faded. The pics are under the HPS glare with white balance set, which gives the deficiency a lighter color. Also took a couple pics of a couple leaves I snipped under natural light.
The problem seems to be only isolated to the "bud" leaves, near the upper parts of the colas. All of the older, larger foliage is unaffected.
Natural light
Very hard to see in this pic starting at the edges of the leaves... thought this pic came out better...
Cupping/curl, sort of
Hard to see the actual spots/coloring on the foliage in these pics, but it is what is causing the cupping/curl.
This plant seems to be the most affected
So if you can help me beat this little problem that popped out of nowhere quickly, I thank you very much in advance. Did lots of comparing in the diagnosis guide threads but I don't think I found a good match, or maybe I'm just stoned.
Either way wanted to see what you guys think!
