Hi! I have one leaf that’s getting yellow/brown spots and some cuts? I would like your help trying to figure out what it might be.
Also I said one leaf but there’s another with a cut and some new inside growth that has yellow spots also (I will put pics of every leaf affected and the whole plant).
I have searched for reasons but this is my first grow so I am have a hard time trying to figure it out…
All help is appreciated, thank you in advance!
- What strain: Malibu Krush (Gelato x OG kush , 60% Indica) - photo
- Age of plant: 33 days
- Method: soil - BAC light mix (with blond and black peat, coconut, perlite, mycorrhiza and a light initial fertilizer)
- Vessels: started in a plastic about the size of solo cup and was transplanted when she was 11 days to a plastic of about 7-11 litters
- Started with only watter (ph 6,9) then at day 16 started feeding her using Biobizz Root Juice and Bio-Grow, 0,5mL of each diluted in 1 L of 6,9ph bottled water and at day 27 upped the nutrients to 0,75ml root juice + 1,5ml bio grow in 1,5L of water. The solution ph is 6,9 and ppm meter shows 210 and EC 0,4.
Also I usually water/feed every 2/3 days and right now around 250ml each time. - Method used to measure PH and TDS: I have one pen for ph and one for TDS/EC, I calibrated the PH one as soon as it arrived but not the TDS/EC (both from Pancellent, bought on Amazon)
- Indoor in a 0.8m x 0,8m x 1.80m grow tent
- Light system: Led SMD Proton 240w Innotech ( it’s dimmable) with a spectrum of 380nm to 780nm and Samsung 2835 Plus + Red 660nm LEDs.
I started with minimal intensity and right now have it at 60/65% (today I got it down to 45% because I thought maybe it was too much for her at this stage) - Current Light Schedule: 18/6
- Temps: day - around 23/24, 5°C / night - around 19/20°C
- Humidity; Day between 50-55% / Night gets to 70% (this is the last few days. Those have been varying a bit, had 3 days where I couldn’t get them over 30-40, and a while back (weeks) had some days where it almost got to 80%)
- Ventilation system; Yes, right now I have an Garden Highpro TTMax 125mm (220 - 280 m3/h) for exhaust connected to a carbon filter, and also and intake fan (190m3/h)
-AC, Humidifier, De-humidifier: No
-Co2: No
The snake looking thing was wiped easily ( shown on the amplified pics).
