Calcium deficiency. Add some Cal/Mag to your fertilizer line up, or if using it already, increase the dosage. Affected leaves won't recover, but new growth should mainly be fine once this is done.

Too little calcium in early flower?
I’m in the early weeks of flower and am seeing this happening. I thought it was due to an attempt at foliar feeding, but those initial problem leaves have been trimmed. Is this a calcium deficiency, and if so, how can I address it? (NLS top dress/coconut powder/recharge)

Defoliation
This is my first auto grow, I usually train and defoliate my photoperiodic plants. I thought just lst will be fine for my first autos. I have 3 bushy plants in my 80x80cm tent and the space is limited. I’m wondering if I can still defoliate them in week 4 of flowering.

Some unknown problem
These are my experimental plants. But it starts to happen whenever I water with calmag only. I water twice a week most of the time, once normally, + cal mag and other fertilizers and the second time I just balance the ec to 0.4 without fertilizers.

Clones with weird spots !
I took two clones from my NL from the side of my plant where I could notice few weird looking leaves. Since they were cuttings they had this spots and I cannot figure out what that is. The plant is growing as normal but looks weird. Is it something that could be fixed ?

Sugar leaves turning white
I am approaching end of flowering, it's 3 weeks remaining. One of the flowers on Laughing Buddha sugar leaves turn to white - first at the edges. I did cut them, should I worry? Or is it normal and genetics related? Pic with most leaves removed but I circled some with symptoms.

Bad appearance
the leaves seem a little clear, strange, I don't know if because they are new, but before they look darker, the amount of nutrients seemed good to me before, but I increased the N to see if that corrects it, I would like more accurate views. I have another genetic using the same

Do autoflower sugar leaves Yellow when the plants ready?
AutoFlowers and Yellowing sugar leaves. Do autoflowers behave the same as photo-period plants when in the last stages of Bloom, their sugar leaves turn yellow? My Maui Wowie are entering week 11 of a 9-10 week grow. (Ambers have Not arrived yet either)

Anyone have any good opinions on what this could be?
Hey guys, I’m about five days away from flipping the flower and I started noticing some spots on some of the leaves, I’m not quite sure if it’s a deficiency or small fungus, I took some close-up pictures it’s nothing serious at the moment but I want to catch it early

Does anybody know what the white tops are? Can be seen clearly on pictures 14 and 19 of week 13. I thought it might be light burn maybe, but it looks too healthy. I also noticed that they start to turn green after some days. Just being curious...
