White dusty looking stuff
GeekSayWhatstarted grow question 5 years ago
I have a pure white substance on the top of my soil, should I be worried. My RH is at 50% and temp is around 26 in the day, and 21 at night. It doesn't seem to be effecting the plant at all. What should I do?
Thanks

I had the same on mine. Just scrape away all visable areas and dispose of. Can add more new soil if you like but let the top dry before watering again. Hope this helps

First Grow 4 weeks into Veg - Let my humidity get too high for 1 night. Need help with mold/septoria/?Last 3 days I've pruned diseased leaves every morning, foliar sprayed peroxide leaves & topsoil, & added some to watering solution. Is only affecting one plant in tent. Humidity no longer issue (was waiting 4 inline fan). If I keep pulling off leaves it's going to die anyway.Leaves. Other

Mould on seedlingThis seed was late to spawn. Now it finally opened, even if it's quite short on the soil. I can see a fluff of mould just below the cotyledons. What should I do? Can I save it or do I risk contaminating the rest of the plants in the growbox?Other. Mold

Genetics or budrot?Hi all, my Royal Jack Auto from RQS is in 7th to 8th week and on the tip of the main cola these red, brownish spots appeared. Humidity has been 50% yesterday and before 40-45%, plenty ventilation in the tent. Around 24 to 28 °C. Could this be the start of budrot or am I paranoid?Other. Mold

PM covered plant sentenced to death - What would you do?I'm about to destroy this plant. Each branch has heavy PM despite having ample airflow. I suspect due to the lack of direct sunshine, but I'm sure it's spread to other plants which will also be destroyed.
Is there anything I can do to salvage? What would you do?
Thanks!Week 15
