Leaf burnt edgesOne leaf has burnt edges and is a little different looking, than the other leaves. Is this some kind of nutrient burn? I am using a light mix soil, and have not fed the plant with additional nutrients, except for a little root stimulant (half of recommenced dosage).5y ago

Leaf spots issueDoes anyone know what is causing the leaves to look like this?
Throughout the whole grow i've had brown spots as you can see in the older pictures, although adding calmag didn't really fix the issue.
If anyone has an idea of what this could be please let me know!5y ago

What am I facing? Plant is getting worst everyday, and I can't find the reason why. Thought it was a calmag def, but now I don't really now.When I switched to flower, I started watching some rusty spots on the leaves of the gelato.
After doing some research, I thought I was facing a calmag deficiency, and starting adding some calmag.
Plant is getting worst, I flushed the roots and water between 5.8 and 6 as canna ask6y ago

To my outdoor growing gurus.. How do I schedule a regular nute feed????doing an outdoor grow and dealing with a consistent rain schedule every couple of days. Can i supplement a feed and give more water (think that's a bad idea), or do I wait until the girls are thirsty again to give nutes? Possible too much rain stunting growth?3y ago

N issuesThis girl suffered from N deficiency very early. So I gave it nutes. Nutes gave it N toxicity. So I flushed the soil with ph’ed water. You guessed it, it’s lacking N now. The problem is the pot is still very yet and heavy so I don’t know if I should water with nutrientsFeeding. Deficiences
