PeppeItaliastarted grow question 6y ago
When I woke up, one of the plants has a tip of a leaf that is dry and burnt. I'm using a 300w LED. Two other plants only have slightly yellow tips on the upper leaves, just small tips. Too many nutrients?

Looks to me like a Potassium deficiency on that leaf(if near bottom of plant). Where on the plant are those pictures? yellow/brown tips can be either nutrients or light burn. Light burn usually has twisted leaves.

Burnt edges / yellowingWhat are all these burnt edges from? One of the burnt leaves is from the perimeter, so I'm not sure how it could be receiving enough light to burn. I also have a small amount of yellowing towards the bottom. That's normal during flowering if the low-light leaves die, right? Thx5y ago

Add nutes or to much?I don't know if it's a heat thing or a need more nutrient thing or too much nutrients. I have only added nutrients twice and it was measured out. I tested the soil with a cup of soil and five cups of distilled water the EC and PPM were almost non-existent

Is this due to the sun and hot weather?Some parts of some leaves are looking like they're burnt or something.
Is this due to the sun? Or do I have another problem?
It has been extremely hot last week (around 35 degrees all week). And the plant has been in direct sunlight (I've moved it into the shade yesterday)

Progressive yellowing on older fan leaves ~F14-F35Hi, past two weeks or so I've been noticing progressive chlorosis and eventually some necrosis starting from the edges of the leaves and working inwards.
Photos of this can be found in Week 18 Flower denoted by "For grow question #x 12/1"
Humidity low, could be related?

The leaves are wierd shaped, but growing fastHi everyone! Please tell me, is it a consequence of leaf scorch with light, or incorrect watering, or I was very in vain in the beginning added root booster? The big question is, is it worth waiting for a potential recovery?There's nothing like it at google
