started grow question 4y ago
Could it be magnesium deficiency or something else? I'm already using biobizz cal-mag with the suggested dose. Tx

I don't think it's magnesium problem. Also not a calcium problem. Is it a lower leaf and has your pH been on point.

Just had a look at your diary. Have you got plenty of drainage because you plant looks a little over watered. Make sure you get run off when u water.

Autogrowing
Auto flowering, PH is 5.8 to 6.1 every day. Hydro set up. Botanicare grow, calmag, and hydroguard all given half the regular amount.
Finishing up second transition week. The bottom leaves started turning a little yellow but are now turning a lot more yellow. Assuming this is the plant just using it's own nutrients stored in the lower leaves. Any input? It's a hydro set up. Thank you everyone.

Deficiency or Genetics
Would you guys guess the yellowing on these leaves is more natural coloration from genetics or do you guys see something more? Plant is definately small but seems to be healthy and buds keep growing.

Living soil growing
Growing in living soil with dry amendments. It’s mid week 6 of flower and lower leaves are showing N/P deficiency. Nutrient teas don’t stop it. Really it has no effect it seems. So Is this supposed to happen at mid week 6? If not how to fix being 3 weeks from harvest?

Yellow tint on new growth
I've spotted some yellowing on new growth. I'm just in the end of Week 3 and am thinking it's caused by nutrient deficiencies? I've been sticking to 0.25ml/L and am planning to go to 1ml/L starting Week 4. Does anyone have any other ideas?
