Toronto outdoor Cinderella 99 and G13

Well here I am at week 9 the G13 seem to be fine Cinderella 99's one of them starting to come along now number one number two showed a couple of these spots as you'll see in the pictures and just from reading a whole bunch of Articles and asking a few questions here and there I kind of figured out that was probably a Calcium deficiency so I added a bit more calmag just to those two and I pump them up till like 5 mil per gallon now I hope I'm right with my conclusion that it's a Calcium deficiency I guess we'll find out in the next couple of days I'll post an update with pictures to let you know what's going on and if I'm doing the wrong thing let me know before I kill them all please it's been a heat wave sitting around 90 for the past week and a half and then at night time only drops down about 80 humidity around 60 all in all it seems to have been a good week. Well I may have jumped to conclusions on the calcium thing there's no other problems with the plant but I was told by someone who has really good experience with this and I've looked at some of his or her grows and the information and knowledge that they have, I believe they know what they're talking about, and they says potassium, so I was advised to make sure that my pH is lower around 5.6-5.7 and basically bump up the bloom a little. this will help provide the needed potassium and hopefully clean up the problem that I may have created for myself by adding more cal-mag than I probably should have. I don't think I have done any long term damage, but time will tell. Most of the plants leaves and everything in between looks pretty good so we'll just have to wait and see. There's plenty of time to go before they either die or I cut them down and enjoy them. hopefully it's the latter. we'll wait and see. I changed the nutes this week as advised and am in the process of getting the ph down around 5.6-5.6. for potassium uptake
