Hi,
My first post here, so hi, hello, great to be a part of this community! Now let me preface with the following - I'm sorry if this thread is misplaced, I'm sorry if I'm being an incompetent idiot with my plant and I make you mad, and also apologies for spelling errors, bad grammar etc as English isn't my native language.
This is my first grow, I'm doing my best to educate myself using tons of articles, materials, other people's diaries, and so on but..
one of my plant (the bubblegum) started crossing leaves, some of which also started turning yellow without any consistent pattern to where the yellowing starts. Some in the middle, some on the edges, one has just a small spot on the tip. I'm keeping it cool but I'm curious about what the cause may be. Too much heat? pH off? K deficiency? What do you think? Pics attached.
1. Plants - Gorilla Cookies Auto (1) and Bubblegum Auto (1)
2. Week 5 in progress
3. Grow - indoor tent 60x60 cm (3.9 sqrt feet)
4. Light - HPS 400w (budget setup, hence no LED)
5. Distance of the HPS lights from the top of the canopy - 20 inches
6. Medium - soil Canna Terra Pro
7. Pots - plastic 17l with drainage holes
8. Nutes -
BioBizz bio-grow (1ml/1l.) /
BioBizz Top Max (1ml/1l.) /
BioBizz Bio-Bloom (2ml/1l.) - TDS - I can't tell you I don't have the EC meter
9. Water pH 6.3-6.5 and temp 72-75f (22-24 C) (I water when pots are light and soil is dry up to about 3 inches)
10. Training technique - LST only, no trimming and defoliation (first time so I'm a bit scared to go all in with the scissors)
11. Temps - Day btw 80-85f (27-30 C) and night between 76-80f (24-27 C) / day temp tends to run higher occasionally even up to 88-89 (31-32 C) but this is a rarity and usually lasts for about 2-3 hrs)
12. rH fairly low due to the climate I live in but around 50% but sometimes drops below 40% when humidifier runs out of water at night)
13. Ventilation is good (I think?), 2 inline fans (1in/1out) and 1 fan blowing air on plants from about 18 inches away
p.s.: Don't judge me on the investment in the boost buddy CO2 bag. Little did I know before buying it :P
