It's probably just from a water droplet or the soil splashing up on it. I've seen it on my first set of lower leaves where they get splashed from watering. Just keep a eye on it.

Raise Calcium up to 150ppm (2ml/l calmag), try not to point the fan directly to the plants. Peace

HARVEST TIME?
I don't know if I should harvest my plants yet. I've been giving them RO water for the last 1.5 week. One looks her pistils are getting too dark, while the other one has a lot of white pistils but many of her fan leaves and sugar leaves are turning yellow already. Should I cut?

Leaf Yellowing?
What is the yellowing in the last pic? The soil is top 20% Atami Cocos, bottom 80% store bought organic super soil. Watering tap water (EC 0.284/142 ppm), pH'd down from 7.9 to 6.5 with citric acid... I think that's probably the problem? Any advice for the high pH tap water?

Yellowing veins?
Any idea what could be causing this? The yellowing stems from the veins rather than between. Any picture I find online of something similar 404s. I might have fixed it in my next set of leaves, but still baffled.

What's my leaf saying?
I just moved my plants into a tent and watered, with nutrition (as above)... I saw two leaves that showed up with a rusty, burn to it... A few thoughts: 1- pH... It's been at about 6.5/7, but leaned a little high this reading. 2- Light burn... 3. Nutrition difficiency?

Weak yellowing leaves
Not every single time but quite often my plants are turning yellow in the middle of flowering. It starts from bottom and follows to top. I can basically “take off” leaves off stem and the upper ones getting dry and brittle. I’m also quite sure the ph level is correct. Any guess?

Upward curling leafs, burned tips, 2nd week of flower
So I'm two weeks into flower now and my leaves are getting burned tips (I'm guessing nitrogen deficiency due to the light green of the leaves or some lock out) leafs are also curling upwards :/. And some fading on some lower leafs. Using biobizz roughly 10ml each Any ideas

Can't deal with yellowing leaves in 4th week of flowering
Been having this problem for a few weeks. I suppose its deficiency of Mag and for the last week or so I've been giving increased portion of CalMag (for 1.5l of distilled water TriPart grow 2.1, micro 2.1, bloom 3, Calmag 12ml). Should I give them more time or its something else?
