New Grower First ever grow, Northern Lights auto. Wish me luck!

Day 11 and second week since taproot appeared - the sunsails are coming along nicely and the 3rd node is beginning to come through.

Won't be long till this lil seedling is a lil vegging plant. Very very slight curling on the serrated tips of 2nd node leaves so think the increased lux is just about ok for now. Once the 3rd node is established I'll need to consider upping the dimmer on the SF1000.
On the minus side, this involves unscrewing the driver unit, removing a rubber plug on the underside and a small phillips screwdriver.
On the plus side, I'll only do this maybe two times during the grow, at the moment it's drawing around 30W and I've moved it around a foot lower. Next I'll bump to arond 60-65W draw and raise fully to find out what lux levels are at canopy level. Once established in veg in another couple of weeks, I'll up it to 100-110W draw for the rest of the grow.

Shes had a little drink today of around 150ml of the remaining 710ppm/pH5.9 1L mix after nothing yesterday, so had 1L in total over the week roughly every other day (in a widening circle around the leaves).

The second week environment has been nice and stable. I'll begin to lower the humidity over the next couple of weeks as it comes fully into veg stage, currently thinking around 45-50% RH in increments over a number of days.

Day 14: no water today. First set of leaves def grey and shivelled.

Looks like it might be a phosphorus deficiency, could be a root pH problem.
Will wait and see if other leaves become affected before trying anything.

So I'm just starting my first ever grow. :biggrin:

Details

Space:
2’x2’x4’ tent. I’ll be trying some LST to keep the height down
Veg/Flower Lights: Spider Farmer SF1000 quantum board running at 24hr schedule. Initially dimmed to lowest setting, around 10,500 lux @ 24" above coco.
Strain: 00 Seeds Northen Lights Auto
Grow Medium: 60/40 Coco/Perlite mix
Nutrients: Canna nutrients: Start, A/B, Rhizotonic, Calmag Agent, PK 13/14, Cannazym, Flush, Boost
Pot Size: Single 3 gallon fabric pot
Ventilation: 4” Black Orchid Mixed Flow inline exhaust fan at 187m3/h hooked up to a Carbon Filter (both in tent). Using passive intake at the moment and a 6” oscillating fan 6" above pot. Inline fan is hooked up to IC308 temp controller to keep temp between 20 and 25°C
Environment: Tent stabilised around 20-24C 60% RH. Got a small dehumidifer which on max setting can lower tent RH to around 40-42.
Water Source: Starting with distilled water at around 6.7pH /50ppm to which I'll add calmag to boost to around 200ppm before adding other nutrients. I have an Apera PC60 meter and a cheapo pen pH meter as backup.


I've got a couple of sensors running from a raspbery Pi to keep an eye on temp/soil temp, humidity and soil moisture.

This is the readings for the last the last 24Hrs.

Got a mini cam set up too as I want to try making a timelapse and for keeping an eye on things without opening up the tent too much.

Got my seed soaking in distilled water lowered to pH 5.5 for about 4hrs now. Will check in after around 12hrs to start with paper towel germination method.

How am I doing so far?
:peek:


Awesome set up bro,

Nice touch with the raspberry pi, i have subbed into your grow! Doing well so far buddy!!

Peace
