I have been reading and reading and belive it "was" bc of defincy. Would like to get some options.

Received the plant from a friend 3 weeks ago. Going to be a mother plant

Fox farm soil(25%) and coco coil(75%) mix

Under 4" t5 4 bulb

LSD strain

Using RO water

First week only watered once with cal-mag. No nutes at all. That is when everything started going down hill(she was extremely heathly when I got her). Tips of water leaves started getting Brown spots . Started with the larger lower leaves then worked it's way up. Freaked out and thought I did something wrong with the cal-mag and flushed at the end off week one. (Noob move I know) I also had a fan blowing directly on her throughout this week which I found out was not the right thing to do. Fan now above her between her and the light.

Week two I get liquid karma, silica blast, and pure blend pro (grow) as well as more cal-mag

Next water(waited till she was really thirsty before watering after the flush). 1.1ec 6.2ish ph with all nutes stated above. Leaves that had Brown spots all started to dry up and fall off and started to see yellowing with throughout older growth. Black spots on the tips of leaves continued to move to higher leaves.

Now to today. The beginning of 3rd week. Noticed that the roots were growing out the bottom of the small pot she was in so moved her to a 5g smart pot and watered her this time dropping the ec to 0.9 due to new soil coco mix and ph stayed the same at 6.2ish. Noticed tips of new growth are turning black as well and it seems like nute burn but I am not sure.
