Hello everyone.
I have these brown spots on my leaves, and no idea what it is. Hopefully you can help me.
Problem: -Brown spots on leaves. Still very small but I wouldn't want it to increase since my plant is young.
-begining of yellowing on one leaf
-First true leaf all droopy and yellow spot.
Medium/grow method: Soil, biobizz light mix
Feed and supplements used: Alc a mic 1.5ml/L. Fed twice the biobizz Bio-Grow at 0.75ml/L so far. Did some foliar feed with water + alg a mic yesterday.
water source: "Cristaline" bottled wated, pH 7.7.
Strain/age: DP's AutoBlackberry Kush, day 15 today.
light used: Mars hydro 300w (135w) at 22inches (recommended 18 to 30 inches)
Climate: 50% humidity, 20-22°C
Additional info: I followed Biobizz advices, they said you don't need to check pH when using their soil and nutes. They also said to start at 1ml/l of grow, and to feed everytime.
I actually just checked the pH of what I fed them this night, and it is the exact same as my water: 7.7.
My best guesses would be nute burn (since I fed them twice already), or wrong pH (despite what Biobizz says), or maybe light burn from the foliar feed? But It wasnt the first time I did it, and they enjoy it like crazy usually (praying hands whenever I do it).
Also, the second plant is fine, and growing strong (although her first true leaves are also a bit droopy).
edit: it might actually be wind burn. Since the stem is weak, my fan was mainly blowing toward her to thicken it. i've moved it much futher away now. however, it does not explain why the first true leaf is dying. Any advice appreciated!
Edit2: decided to cut the sick part of the first true leaf. It really looked Bad, like it was being eaten... See the last pic.
