Jack Herer automatic

Hello, a couple of weeks ago I started my first grow ever, but unfortunately due to overwatering she got larvae and died. So this is my second attempt of growing Jack Herer automatic in my attic. The first time I mixed 75 grams of fertilizer in the soil, this time I halved it, so appropx 37.5 grams, because the tips of the two leves that the had were starting to color and point up. It may have been becaute of the over watering, but I can always add fertilizer, but I can't take it away. I started giving it a whole lot less water and she's looking good for now. I'll also wait 2 to 3 days before watering again and hopefully it will go beter this time.
