Tubington9
started grow question 5y ago
I seem to be experiencing nutrient burn and nitrogen toxicity, is this fixed by just flushing with PH’d water for the next couple feedings?

Nutrient Burn?
Is this nutrient burn? I started giving her nutes on week 2 at eighth strength (Bio Bizz grow .2ml/L), then slightly increasing to quarter on week 3. The soil I'm using comes lightly fertilized, so maybe it was too early at week 2 and 3?

Leaves tips look burned
Any suggestion of how could make her look healthier? Tips look burnt and leave color is not great. Also my plant is very short, 25cm. I didn't feed her any nutrients so far, only water pH6.5. The soil (atami kilomix) was heavy fertilized with bat guano. Is she needing something?

Weed doctors to the rescue
Day 44, fb auto, my happy girl developed those dark spots at the top... Is this a Calmag deficiency? Although I'm giving her calmag every feeding. I think there are also first burnt tips. I'm about to water her tonight, what should or should not give her? Thanks for your inputs🙏

Why is One growing perfect the other is struggling
Why is one of them doing so well growing better deep green leaves and the other is at least 2 inch shorter and leaves are yellowish. I’ve been feeding them both the same I’ve missed the shoter one of the soil is still damp. I’m guessing nutrient over load so thinking do a flush

What do these yellow markings on the leave tips mean?
What do these yellow tips on the leaves mean? Are my lights to close? Looks like light burn to me and have adjusted the lights up 10cm for now. Still wanted to make sure since I thought they need more lights during flower. Thanks heaps

Nutrient burn or under watering?
several leaves getting yellow at the tips. have not made any major changes to the environment in over 2 weeks. Water ph is 6.3. I am leaning towards under watering since the bigger of the 2 seems more affected. How would a more experienced grower proceed?
