yellow/brown spots on lower leaves
AlpAge_Cinostarted grow question 3y ago
Hi, 2 of 8 got yellow/brown spots on lower leaves. I've watered them once a week and add calmag, pH=6,2 following b.a.c. instructions. Last watering, i forgot calmag so I did a second watering 5 days later with calmag. What could be the problem ?

They just need more food. Looks more like phosphorus and potassium deficiency starting, the burn straight tips say more then just a magnesium deficiency

Calcium deficiency.
Over watering could also cause this.
Even if only Watered once, it could cause the problem if the soil don't have enough perlite or vermiculite..
I would add a little more calmag in your next feeding. Goodluck broskie

Phosphorus? Potassium? CalMag? What is going on here?So in week 8 after flushing with EC 0.4 and giving extra PK 13/14 afterwards (EC 1.9) there are still problems occurring. I personally think itās a deficiency of potassium and phosphorus. Can anybody give me some advice or tell me how to fix it? Thanks!

Potassium, correct?I think this is the beginning of a potassium deficiency. The near neon green discoloration is what caught my eye. This leaf is affected the most.
Second week of flower. The Alga Bloom was just increased from 2 to 4ml/l earlier this week, so she should be alright. Right?

Possible N ToxicityI believe I have a N toxicity issue on my hands. Leaves are a dark evergreen color, and I'm noticing some leaves are curling left or right. I've experienced the full out clawing action a while back but never like this. Is anyone able to confirm? How do they look overall?Thank U!
