Do you think it's too much or too little fertilizer? I enriched my old soil with worm humus and premix, all from Biobizz. The humidity is consistently at 60%, and I currently have a PPFD of about 430. Since the 2nd week, I've been adding half of the recommended amount of Bio Grow from Biobizz.

Yellow leaves at the bottom
Some few leaves, two older and two new ones, turned a little yellow. All of them on the bottom of the plant. I don't know if this is a normal development or perhaps Na deficiency? It's my first grow, so I don't have experience. Help would be appreciated.

My BB3 is having problems. Pale, leaves are drooping. 4 months old and has been in 11L BB Allmix for about 2-3 weeks. I'm watering with Biobizz (5ml Grow/1 Bloom), can't measure pH. I have thrips that I can't get rid of (treated with Neudorff insecticide and aphid-free). Light & temp are fine. Anyone have an idea?
