PE636's Purple Kush Coco Grow

Noticed some classic Calcium deficiency signs on the PK last night, a handful of upper leaves with lots of brown spots and a little wilting, will get some pix at lights on today....
I've been giving lots of calmag so decided to check my ph meter. It was reading .6 high! Thought I was feeding 5.8 or so and it was more like 5.2 ... A quick perusal of the forums and web show this low ph could cause Calcium problems especially in coco. So starting today I will raise the ph over a few days and hopefully that will fix things up. The two white widows are showing no signs of problems but I'm sure 5.2 is lower than ideal!

The apparent Calcium problem on the PK does not seem to be getting any worse. Removed a bunch more leaves and small shoots especially from the white widow plants the colas are very leafy compared to the PK! Day 35 from the flip about 25 from start of bud formation

Day 30 of flowering or day 42 of 12/12.
White widows are both looking super healthy and pumping out the good stuff!

Purple Kush is doing well, buds are fattening up slowly but surely and look pretty frosty as well. You can see some of the damage from the alleged calcium problem, hopefully it doesn't affect the buds too much it seems to be on just the same handful of fan leaves, might have gotten a bit worse since I noticed but hasn't spread.

Me too! I really don't know how much to expect since it's my first time. I've smoked a lotta weed over the years though and this looks like a good bit! Any guesses what I might be looking at? Hard to tell from pix I suppose. I guess the buds have quite a bit of swelling to do yet as long as I don't screw anything up between now and the finish line!
