First grow, Sweet ZZ RQS

Week 5 and its been a hard week on my sweet zz lady. Stressful week filled with so many first time grower mistakes. I think in this week I commited every growing sin there is. First error i made was to over water which i believe in turn lead to over feeding. And to add insult to injury my ph tester was off and the water ph level was actually 8.2 and not the ph6.5 I believed I was feeding her. So all in all i have over watered and caused her to be sad/stressed and droopy, then over fed causing nutrient burn on the leaves and most likely nutrient lock out. Also signs of calcium and magnesium deficiency have well and truly set in. Its been a heart breaking week. Was almost going to pull the plug and scrap the grow. But then if I was to give up, what would I learn. I guess the best way of learning how to do something is learning how not to do it. First time growing and I have to admit, having a first few great growing weeks had maybe made me over confident and that's when the mistakes began. I am not going to give up on her and I will see this grow through to the end and learn from it. To tackle all my problem's I first let her dry out for 3 days then I flushed her with ph adjusted water only (new ph pen properly calibrated). I removed the worst of the infected leaves and any others that have deteriorated as the week went on. When she was ready for more water I added in some biobizz cal-mag to try and get on top of her calcium and magnesium deficiency. I'm watching her closely and will never take her for granted again. I hope all this hasn't been to stressful on her and I can get her to harvest. Shout out to those how took the time to give me some much needed advise this week, was truly appreciated. Many thanks.
