It’s the first symptom of over feeding. The plant isn’t using all the nutrients and salt start to form in the substrate. You’re just slightly a bit to high, lower your feeding solution (100-200ppm less). Control the EC of the drain before and reduce your feeding solution.

This has happened to me a few times and its always right at the beginning of flower. I believe its the very beginning of nitrogen toxicity. As the plant shifts into flower, it wont need as much nitrogen. I just backed completely off my veg fert (Your Part A I believe), and the yellowing never progressed past the very tip! Hope this helps, plants look great!

It's likely either heat stress or too much bloom nutes locking out your micros.

DeformationHello friends, how are you?
I have a big question about one of my plants. Right after the appearance of the first two pairs of leaves, I noticed it's not doing very well. It's now 15 days old and seems to be starting to flower.

What happens to my autos ? Too much fertilizer ? Nutrient block ?First week I tried the devil and fertilized my autos as little as possible, knowing it was useless... Big mistake.
After that I could see signs of too much fertilizer, i.e. pointed leaves and since then, slow growth with very small leaves. What has happened?

Northern Lights Auto, quite short and bushy, fan leaves shielding light - should I defoliate?First time grower with a quite short Northern Lights Auto in week 6. The fan leaves seem to shield a lot of light from the inner leaves, also touching ground. Should I trim the fan leaves? Or should I keep them, since it already seems stressed enough for it's short life…

Feeding right after repotting (coco coir).After repotting an auto flowering plant I get runoff EC of 800, while feeding water has EC 1200.
I guess EC gets diluted (biggest part of coco coir is new).
Should I increase EC of the feeding water?
I see slower growth but it may as well be due to stress of repotting.Setup. Strain - Autoflowering

Too small auto having pistils. Is there any way to promote veg growth?My almost 5 week old gorilla cookies auto is very small for its age but has pistils.
Is there any way to promote veg growth or should I give up?
Plant was neglected for first 2 weeks: cold temperature, water with too high pH, coco coir with no nutrients...

What is that?Yesterday evening feed 0.5 litre EC 1400 pH 5.9. Runoff was EC 900 pH5.6
Increased light intensity to PPFD 600.
This morning larger upper leaves are in "praying" position, one leaf closer to bottom looks sick.
If it's a light burn, why not on upper leaves?

Some guidance for ScrOG please@22cm & preflowering for about 4-5 days. Haven't noticed any stretching (~2-3cm)
When do I start with the ScrOG and at what height should one set the net ?
Also curious about defoliation: Right now, I keep tucking the fan leaves under the smaller ones.
