Hello,
My name is Hugo and I'm looking forward to the day when I'll be smoking my own good quality cannabis, BUT I still have a lot to learn and I have a problem that I can't solve and i'm getting really frustrated. I It's the second time my 6 plants start to yellow at 3-4 weeks into bloom and when i change my light from MH (bright white light for the eye) to HPS (a lot more yellow looking light for the eye).
Gear
Grow tent: 100x100x180cm (40x40x70 inch)
Square 11L (2,9 Gallon) pots 22x22x26cm
Grow lamp MH 600 Watt Sonlight - Veg
Grow lamp HPS 600 Watt Sonlight - Bloom
Sonlight Digital Ballast 4D (Dimmer 250 / 400 / 600W / SL (Super Lumens)
LONG-GLOSS 50 V reflector
Carbon Filter: Prima Klima - Filter ECO line ø10cm - max 240m3/h
Extractor: Blauberg BI-Turbo ø10 cm - 187m3/h
Nutrients
Canna PH- (min) Grow 1 liter
Canna ph- (min) Bloom 1 liter
Canna PH+ (5%) 1 liter
Canna Terra Vega 1 liter
Canna Terra Flores 1 liter
Canna Rhizotonic 500ml
CannaZym 500 ml
CannaBoost Accelerator 250ml
Canna Cure 750ml (handspray)
Soil
Canna Seed Mix 25ltr
Canna Terra Professional 50 liter
Canna Terra professional plus 50 Liter
My first grow plants died due to the same problem that occurs now. Yellowing of all the fan leaves, then spreading. I don't think the problem is pH because I grow in soil giving water at pH:6-6,5-7 variating every time. Don't think it's nitrogen defiency because I had an nitrogen burn in veg and flushed them all and giving them low to medium quantity of CANNA bloom nutrients. I did have spider mites, but got rid of them with Canna Cure spray and BAC Plant vitality plus. I changed my light from MH to HPS (both 400 Watt), and the yellowing started. I find it hard to believe it has anything to do with the lighting but I'm getting desperate here.
Pictures coming later this day.
Thank you
