GG#4 First Time Grow

5/28 Leaves are looking a lot better now that they have some room to spread themselves apart, no signs of furthering nutrient problems or overwatering issues. 5/29 Noticed what I'm pretty sure is a potassium deficiency. Freaked me out at first but the browning tips looks exactly like the picture I see online. It's not very widespread so I cut the effected leaves off, I'm hopeful it's residual effects of the insanely high ec. Regardless of the issues the plant is still growing really well and I was able to tie down a main branch around the entire pit almost except one area, but that ended up making it easier to water. 5/30 Potassium deficiency has spread a little but not much. Even though I watered till runoff yesterday (as I always try to do) the plant was dry and light today, so I watered her with nutrient solution at about 1.3 EC and runoff was about 2.2, little too high 6/1 Calcium toxicity. Shows as brown reddish spots and can present as potassium, manganese, iron etc deficiencies which is exactly what I've been seeing. There was quite a few leaves showing the blackish rust color so I cut them all and watered with nute solution at ~.72 EC. Will see if the problem continues to develop, however judging by the color of the growing shoots she is still growing quickly. 6/2 I found a couple of leaves that had evidence of damage but they were so hard to find I could very well have missed them the other days. I cut all effected leaves I could find off again, and will check tomorrow. Rearranged the plants a little to avoid this one from getting blasted by space heater. Untangled all growing shoots. 6/3 Found I think two or three effected leaves, mostly already effected leaves that I had just cut the currently effected blades off of the other days, and one leaf that looked too far damaged to be new damage but I will remain vigilant. Watered clean water, runoff ~1.75EC, almost where I want it.
