It’s my first time growing and I’m here to ask for your help please. It’s day 56 and the leaves have some spots and yellow edges.
I’ve been trying to make it as simple and natural as possible, from my research I tried to use the following, I’ll share more info:
Strain: blackberry auto
Day 1: August 7th
Soil & Veg: planted in the final pot (16l) with plagron lightmix adding only Mycorrhiza in the soil and adding bacto once a week during waterings
Nutrients: started using 1-2ml/1liter (for 4 plants) organic bloom BAC during second week of flowering (Day 36, day 45, day 51)
Average temperature: 22 celsius
Average humidity: 62%
Light: 18h, Led series 600 (Viparspectra)
Both of the blackberries have the same symptoms, do they look sick? Maybe it’s due to nutrients and I should cut the BAC? Light? I’m a bit lost.
Welcome to GN. Your blackberry looks great. It might be early signs of nutrient burn or a pH issue with your water or soil. I think I can also see signs of spider mites. Look under the leaves and look for really small insects or webs. Plan B might be needed.
Thanks a lot @chrisj! I’ll check more carefully for spider mites, so far I couldn’t find any insects or webs. In case I do find them, any special tips to treat them during flowering?
