leafs with brown spots and olders become yellow and curled
GoldenWeedGrowerstarted grow question 5y ago
I'm trying to figure out what is the problem with the growing of my plant.
The upper leafs are quite normal, even if they tend to bend downwards.
The old leafs start with brown spots and then they become yellow and curled on the peaks.
Please help me to understand what's going on

You need a full res change. That will probably solve all your problems. Check my GDP diary veg weeks 4 and 5. Same issue.

Nutrient deficiency? If yes, what's the best course of action to salvage the situation?First time grower of 3 autos, at week 8, lower leaves started turning yellow, top leaves started to get smaller/develop brown spots 2 weeks ago. Is this a nutrient deficiency problem? Soil should have been fertilized for 3 months, but I'm thinking they burned through it.Leaves. Color - Pale

Brown little spots on leavesHi, I went on vacation for 4 days, the ec went from 1.2 to 0.5 and many small dots appeared on a lot of leaves. Do you think it's due to that ? The ph went from 6.2 to 6.4 but I don't think that's it...
Thank you for your answer :D

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.
