PDS 1st Grow - Misty Kush

Started seeing some signs of nutrient burn after being told I was using too strong a solution so I have backed off and started using a new feed schedule. Due to sharing space with autoflowers I plan on keeping these in veg for another 2 - 4 weeks while the autos get closer to harvest. Misty Kush #1 - I have done very little to this plant since finishing topping it for the mainline. I am occasionally seeing some small brownspots on a few of the leaves that look like a minor calcium deficiency. It only appears on a small number of leaves. Raised the PH a little to 6.2 to try to help with calcium absorbtion. Misty Kush #2 - Finished its third set of toppings last week and has been recovering nicely.
