Hey folks having some issues with my plants they had started to yellow from the bottom up and have stunded in growth I read what I could and though it was a calcium issue.. add some calcium a few days ago but not all the way better tryed to figure it out on my own but I've to admit defeat... I think it may be a nitrogen issue but I'm grasping at straws here

Couple Of things really, I think its a potassium def, but i think you may also have thrips, there are some classic signs of thrips there man judging by the patterns of the leaves. Take a close look at some of the leaves with marks and see if you can find any bugs in the margins of the leaves. Other than that, a slight increase in PK booster should fix the problem Smile

Well its not easy when your plants are so far into flower. you dont want to spray anything on the bud, it might just be best to get some sticky traps in the tent and hope for the bestΒ

I think Macky is right. You can make your own magnesium solution by mixing 1/2 teaspoon of epsom salts to a quart or liter of water.Β  If you spray it on the leaves (when the lights are low), it will be absorbed right away, and the plants will look much better in 24 hours.Β  The trouble is you are in flower and you definitely don't want to spray your flowers.Β  Maybe one option would be to apply it to the fan leaves with a small paint brush. Turn your lights back up after the solution is absrorbed/dried.

Did you find any hints of bugs?Β  It does look like thrips in the photos.
