First Grow - Meph CDLC

Issues!! For the first time, I open the tent and leaves are clawing, tips are burnt, THE END IS NIGH! After freaking out and over-Googling, I rethink how much CalMag I'm using, how much I'm watering and if I should be using distilled water over tap (I shouldn't). Switched to tap- Not watering enough also contributed. Watering every other day now, instead of every 3rd day. Added 1 tsp CalMag to every water/feed but still feeding every third day (so WxWxFxWxWxF so just feeding once a week, and Recharge for 1 W per week). I'm adding 2 tsp of BULK this week, then 4 tsp in Week 9, and 8 tsp for Week 10. Some rust spots on Day 50 but by 53 seemed confined to just few older leaves, clawing improved and tips stopped burning after the CalMag change. Day 52 Needed garden staples and Defol to get some light in, lots of bright green growth now looks happier. Can't wait to see where this goes! Just WOW Mephisto!
