Let There Be Weed - My 1st Grow

1) new yellow leaves with brown spots started to show up in Shakira. They are not easily plucked but they fell papery and "break easily". Possibilities are: - it's a calcium deficiency, but the pH is fine (6). CalMag is on its way. - the temperature of the water was too cold so there may be a problem with the nutrients Absorption - i defoliated too much and that generated nutrient deficiencies (not sure if this is a possibility) - because humidity is being a bitch, it can be a fungus. BUT she is sitted VERY close to another plant that doesn't how the same Simpsons. Fungicide is on its way too. 2) Gertrude's development is late compared to Shakira. Sher buds are still made only by white pistils. I wonder if I fucked up when I transplanted her to a new pot and now she won't grow, or if she's just slower because she USED TO BE in a smaller pot and have a high pH. Other than that plants are ok, and humidity is constantly high even though the dehumidifier is on 24hrs a day.
