It’s like a micronutrient def, Zn causes the necrosis on tips of the leaves in a immobile way. Maybe combined with Mn that causes that one in the middle of the leaf. Are u sure to give them enough calmag?

Yellow and fragile leaves 2 week
Couple leaves yellowing and bit curved up. I suggest there can be the options: 1) magnesium deficiency; 2) nitrogen deficiency; 3) Light burn. For case it is magnesium deficiency I sprayed the leaves with magnesium sulfate (solution - 1g per 1 liter), but it won't help.

Please help identify my Problem: Yellowing leaves with veins showing and some necrosis spots in third week of flower
The odd thing is that only some leaves in the middle of the plant are affected. My thoughts were Nitrogen or Manganese deficiency or maybe light burn (why in the mid of the plant tho?)? I feed Biobizz Bloom, Grow and TopMax, no Problems until now.

Yellowing Budsights Early Fower (organic grow)
I fed the plants yesterday and noticed that it was too warm in the tent. (86F) So I change the light time to 9pm-9am. As a result, the plants had 24 hours of darkness in the tent. When I turned on the light today I noticed that some of the buds had yellowed. pH (soil): 7,8-8,4

Seedling yellow leaf ?
A pair of second set leaves have sign of yellowness (it occurred a day before transplanting). I'm not sure whether it is Nitrogen deficiency or any root problems? (I will start adding more Veg nutrition which is rich in N this week) Can yellow leaves turn back into green?

Over watering? Asked a similar question before but want to save this plant
This has gotta be overwatering, right? The soil + pots I'm using don't seem to drain very well. Started drooping like this when I added a humidifier at around 70% relative humidity. Maybe pushed it over the edge? Going to home depot. Perlite? Change out the soil? Better pots?

Yellowing Too Fast Or Natural?
I'm roughly 2-3 weeks into flower. Over the last week, I've noticed more yellow leaves than normal. Majority are bigger, older fan leaves but some are moving up the plants. New growths are a nice green and buds look healthy. Am I under feeding or overreacting?

I need advice on what to do with this plant. I flushed her a bit and I think nutrient burining is not showing on new growth, what ppm should i feed her?
I watered only last week and mesaured runoff ppm and ph. Water was 350 ppm and 6 ph and runooff was 700ppm and 6.7 ph. Before when i fed her with 850 ppm runoff was 1500 ppm. I would continue to water only but there was a lot of yellow and pale leaves so gave her light dosage.

Any clue what this is? About to be week 6 and in flower. I'm thinking the start of nute burn? I gave it bloom boost in the last 3 waterings in less and less amounts. let the soil get very dry before watering with plain 6.2 pH water. Any input is appreciated
