Do you think it's to much or not enough of it,i had a idea it was the k but wasn't a 100% on it,i definitely knew that was a ca deficiency but again is it to much or not enough, i got shogun cal-mag ere an shogun pk 9/18.i made a mistake of giving them advanced nutrients B52 an that's got 4% k init,only a few feeds with it but then i noticed the 4% k in it an stopped, so they were having the k at 18% from the pk 9/18 plus what was in the actual bloom which i have no idea on the NPK cause dutch pro don't let you know on the labels, so im assuming it's way to much,even though i only been using 10ml of A an 10ml of B which it no way enough feed for 5 weeks in flower i know this but the directions on the shogun pk 9/18 state to drop your main feed by 25-50% because of the high amount of k,i lowerd mine lower not much,there not hungry unless there needing more k but i can't see it,thats why i ask if i have put to much or not enough in,it's only centered under the light,that picture were the leaves are yellow an drying edges is the only branch on the plant that looks like that the rest are ok,like i said it's only centered under the hpsLooks like the start of a Ca- to me as well. The other one is a K issue in my opinion. For the Ca, go with both foliar and root drench applications, you've caught it early so can probably easily stop progression. K issues are pretty easy too, I usually go for seaweed but other products will work, too.
My own experience with bleaching, the plants looked just like someone had thrown bleach on them. Uneven areas, bleached white. I wonder if I have any pix still... hold on, gimme a sec. The bleaching started after I put the 600W HPS they'd been under on a mover.
