1st Time Grower - Plant#1 Mystery Strain

Hey Growers, end of week 12 from seed Not much has changed this week, its been a slow bud growth. I feel it still needs to grow thicker, 2-3 weeks before flushing Smell is a bit stronger, hoping a sour flavor. It been difficult trying to maintain a steady humidity level due to weather outside. I will consider buying a stronger humidifier for my next grow. Trichomes are cloudy, no amber yet Some of the leaves have yellow-orange tips, this happened after I changed ph meters, my old one broke so I had to purchased a different ph meter at my local hydroponics store. Will keep you guys posted, see you next week
