what is the problem?
RoyColt
started grow question 3y ago
The colors of the leaves make me think. I don't give a knock during these weeks of bloom time. Do you think this is a lack of calmag? or this is normal:)?

Losing colors :'(
I watered only 2L of water without nutrients this week (pot 30 L) You can see it on the diary photos, the plans have lost their colors (yellow). I wanted to know what exactly it was due to, because I read on the net a lack of nitrogen but I would like the expert opinion Thanks !

Spots on leaves
One of my girls seems to have some spots on the leaves. She has been like that ever since sprouting. Is it just genetics or is it potentially a disease?

HELP—Trained eye needed for a nutrient deficiency diagnostic!!!—HELP
Can anyone help me with diagnosing what appears to be a nutrient deficiency? I used Jobe's fertilizer sticks (13-4-5) [I know, horrible stuff but its all I could get for the next two weeks] which I diluted to 1/8, 1/4, 1/2 of the recommended amount as per label. CHEERS!

Why do I have rapidly spreading yellow on my leaves?
I have this yellow spreading on some of the larger leaves and it's moving super fast. Please help. I've done research and it says it's a deficiency, mostly likely cal/mag. I added that and it got worse, now I'm thinking nutrient lockout? The pH is fine. What do?!

I'm entering week 7, what's happening?
I'm entering week 7 from germination. I'm using a soil for herbs/lawns (pH 8) as an amendment—not ideal for cannabis. I'm testing it, but leaves look like this. I fertilize and already flushed. Using 1ml grow + 1.6ml bloom Biobizz in 500ml water (pot is 3.2L).

Leaves losing "color"/turning yellow-ish. (autopot without nutes)
I've been using autopot system wihtout nutrients, plants now went to bloom. Could the smallest of the bunch (NorthenLight left down corner) have some defiency? As others are not "complaining", at least yet. Should purchase nutes that work with my autopot, only biobizz left now.
