Hi all,
I hope you people can help me with my first attempt on indoor growing. I planted 3x Arjan's Haze #3 (70% Sativa, 30% Indica, small sized) on the 14th, they sprouted on the 17th. The small pots have 7 cm side length. Lighting is 2x80W PL-L, about 15 cm away from the plants now (I started with half a meter, hence the thin & tall growth). Daylight temperature (18 hours) 26-28°C, nighttime 18-19, ventilation 160 m³/h duct blower running at 170V + 5W fan blowing towards the lamp, 60x60x120cm box.
The soil is Frux sowing + cutting soil, ec 0.3-0.7, ph 5.5-6.5. Tap water should be somewhere around 7-7.5 ph.
I have larger seed pots (0.7l), also 8.6l and 11l. And I have a bag of Growmix soil, ec 1.2-1.6 plus Biobizz BioGrow fertilizer.
Here is a photo from the 23rd
The second plant had problems with getting rid of its seed shell, so I manually removed it.
One from the 25th. Identical camera settings, gives you an idea about how dark the setup initially was.
And one from the 29th
Something is clearly wrong, especially with the plant in the front, which matured first. Stems are violet, and the smaller leaves are starting to get violet too. The other plants are also losing vigor. Growth has slowed down, resp. stopped for the one in front.
I've read about too much nitrogen as a possible cause, but I didn't use any fertilizer, and I don't have gauges for ph, ec values and so on.
I thought maybe I overwatered, but the soil is rather dried out now, and it doesn't seem to change anything.
I'd be happy about any ideas...
