Is this some sort of immobile nutrient deficiency or excess? Could this be caused by heat and light stress? She is 80cm tall and almost touches the lights in the tent. I'm usually suffering from Calmag and Nitrogen issues and haven't yet experienced yellowing from the top. Thanks

Manchas en hoja
Hola! Aparecieron estas manchas en una hoja de una GG#4 de zamnesia en su quienta semana vegetativa. No es algo que me preocupe, ya que la planta tiene una apariencia sana y crece vigorosa. Pero nunca vi este tipo de manchas y me gustaría saber su posibles motivos. Un saludo!

Yellowing leaves, why?
Her leaves started to yellow, probably because she was dried out for one day, so I watered her properly with 1.5l with 5ml of biocanna flores(first time). After 3days I would expect her to be dry again, but the soil is still quite moist. Why is she drinking a bit less?

What deficiency is this ?
What is happening to my plant right now ? I believe it is calcium deficiency also could be Manganese from the pictures. I did not add CalMag during the first weeks. Usually Calcium deficiency shows after 4 weeks and during flower but not likely in soil. Started around 6th week

Can anyone tell what is causing these yellow tips on new growth on this plant?
I noticed my DLI was around 42 at the top of this plant so the light may have been too strong, or it could be a nutrient issue? Using CoM Stonington soil, plant is 26 days old. Haven't added any nutrients to the soil yet.

Week 8 (4 weeks into flowering) - Possible Nitrogen / Cal-Mag issue?
Plants show signs of what i assume to be a deficiency. Stopped feeding nitrogen Week 7 according to schedule. Symptoms are not on every leaf but some the upper foliage. Yellowing, burnt tips and rusty spots. My guess is lack of Cal-Mag & Nitrogen. Is my guess correct?

Yellow parts on very young leaves
She's only 2 weeks old and some leaves started yellowing. Should I be concerned or it's a normal thing? Watered her a few times with distilled water (no nutes). Also, there is about 30-40cm distance between the plant and the light (SF1000, put on ~50 power)
