This looks like nute burn. Flush and make sure to give it calmag with the next feedings. Make sure you pH is good as well. Fixing this should stop the spread.

Hi people, need some serious help here. The new leaves look like sh¡T. They are kinda yellowish and the tops are necrosed. Some spots on the leaves too! I added some silica in the last water but I don't know if was the cause. Soil pH varies between 6.5 and 7.0. Any ideas?

Is this nute or sun burn? What should I do to save my babies ?
I upped the nutrients to week 2 of veg state (biobizz) and put the light to 50% intensity. I put the light at 6 inches above recommended height (which is recommended on the Mars Hydro website for beginners). . IS THIS NUTE BURN OR LIGHT BURN?

Is it time to flush or wait a week?
Hey what’s up grow gang, we’re approaching the final weeks of flowers, but I was curious as to if our grow is ready to be flushed, or if they possibly need another week of nutrients, and also the best flush technique for best results. Thank you for answering in advance!

Blätter gelb und fallen ab Blütewoche 9
Aktuell machen mir meine Pflanzen echt Sorgen, viele Blätter werden sehr schnell gelb und fallen von allein ab obwohl ich bei jedem gießen Dünge. Sollte ich noch mehr düngen und häufiger gießen? Die Buds sehen soweit gut aus nur sind bis jetzt immernoch mehr weiße Haare als Blüte

Yellow spots on leaves
Hi, I've noticed these spots on the leaves, does anyone know what they are please? Leaf Septoria? I hope not. It's a soil culture under leds, I used Biobizz products (Bio grow, bio bloom, top max) with biobizz calmag, I adjusted the ph to 6.5 with biobizz bio down. Thank you,

I'm still trying to raise my soils pH, I'm using Olympus up which has lime, should I give a higher dose or jus pH water till pH runoff goes up?
If I use nectar for the gods Olympus up which has lime in it and I'm having low soil pH probs, should I use more Olympus up and adjust my pH and would that help raise my soils pH? Or should I jus use pH water until my pH runoff is where I want it? Advice greatly appreciated.

Nutrient Burn or Deficiency?
I recently fed her nutes and two days later I am seeing this yellowing on the baby sugar leaves on top buds only. Do I flush? Or is this a nutrient deficiency and not a nutrient burn?

PH Fluctuations and/or Nutrient Issues?
I'm Running a Recirculating Deep Water Culture System( hydro). Had PH dropping dramatically a few days back but did a full water change and everything has stabilized. Just Flipped to a 12/12. Does it look like that was the issue or is it nutrient toxicity/deficiency. Or Stress?
