3 possible reasons. 1. This plant wants more nitrogen or ph levels are slightly too high. 2. This plant is more sensitive to light and doesn't like it being so close. 3. This plant has red /purple genetics and a different "pigment" 🌱👍🌿

CalMag issue. If your giving them enough nitrogen (talking about BioGrow) then this is definitely a calmag deficiency. 😎

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)

Going coco with coco coir!
How often should coco be watered? Some people say every day some people say wait till coco dries up a bit, then water? Been watering every 3-4 days and ive had all kinds of deficiencies. Not sure if it’s from the amount of nutes I use or I just don’t water often ? going coconuts

Bottom fan leaves turning Yellow on week 8... Emergency, or all good ?
I know It's a Nitrogen deficiency. No nuts during veg (and fine!), and she's having flowering nuts since 2 days. I know it's normal at the end of the flowering, but i'm wondering if that's too soon !? Not sure how many time left before harvest!? Big problem or not?

What’s your opinion on this one?
What you think about it? Is she getting too much? I’m not giving her too much in my opinion. Her stems are purple and the leaves are yellowing a bit. Watering always with ph 6,3-6,5. Thanks for your help! Happy growing!

The leaves started to turn yellow from the inside out. I don't know if it's a disability or an overdose. I'm using Biobizz. Someone solve? Is it in flowering with about 5 weeks to harvest, is it worth stirring or better leaving it like this?
