HomeGrow Basic (100x100x200) with Cooltube 400W HPS (Pics)

I have recently bought all the necesary to make an indoor.

The seeds are Thai Fantasy and Original Berry, from Kannabia.

I use as fertilicers Terra Vega and Power Zine, I water my plants with 20 ml by 10l water of Terra Vega and 40 ml by 10 l water of Power Zine, I have started using them on July 7

The soil it's Terra Professional by Canna

The light it's a cooltube with a 400W agrolite lamp and it's above the plants like 55 cm. I use a temporiser set with 18 hours of light and 6 hours of darkness.

The water's PH is 6,5

June 18 I started to germinate the seeds, I bought 10 female seeds and 8 germinated

On July 5 the HomeGrow was all set and I place the plants inside, the plants are inside 2 l cubes

Measures (temperatures and moist maximun and minimun) and heights in cm (by order in the pic)

Pics from 8 July, the first pic are all the plants and the three next are more close pics of the three first ones.

Any coments or suggestions are welcome.

pretty sweet but can you at least fix water to be 6.9 to 7.0 ph? and degree should be 68-70

I was told and I have read that it's better to have PH between 6.0 and 6.5

The degrees are in celsius (world wide measure except for US)

30 celsius = 86 fahrenheit

nice start dude, i have also been told that about the ph, been doing it and i am getting alot of bud...

I have a question, I was told by a friend that it needs a week more in order to change to flowering, but I have read that the usual period of time to grow it's about two months.

So what is right then?

looks nice,did you buy a cool tube,cooltube reflector or did you make one? if homemade,can i see a pic of your cool tube? (if possible,Thanks) -peace

p.s.
its up to you when to switch to 12/12,i agree with your friend,i'd wait another week (maybe 2) to flip. it just all depends on how tall they can get and still be under the light with enough space between the cool tube to not fry them or make them react to heat issues.

the usual cycle is 8 weeks veg,and 8-12 weeks flowering (depends on alot of variables and strain though)

The cooltube I bought it had a reflector.

How many cm I have to left between the plants and the cooltube to calculate how much the plants can grow? (in order to know when to put the plants to flowering)

well usually most strain double,sometimes even triple during the flowering process.the main growth usually happens a til about 3-4 weeks into flowering

I have a problem with some leaves, they have yellow spots.

I have tried to move up the cooltube and retire the fertilizants.

Anybody knows what kind of problem can be this?

The higrometer it's crashed, may be tomorrow I can buy another one.

Looking good.

yeh they DO look nice. I would say you could change the light anytime you want to now.
