First grow - how are they looking?

[Tic tac toke]

Hey! It's my first time growing and my first post on this forum!

I have been a lurker here for a while, and have just started my first grow so I'd like to get some feedback/thoughts on how I'm doing .

Setup
300w Viparspectra light set at 30" above the seedlings.
2x Fat Banana autos 2x Quick One autos.
2x2.5' Gorilla Shorty tent.
Prima Klima carbon filter.
Prima Klima Radialventilator 2-step 240/360 m3/h exhaust fan.
Humidifier.
1x 160mm clip on fan.
1x 200mm oscillating fan.
I will be adding a 200mm ducting as the passive intake as at night the tent has too much negative pressure, and I don't want to use the passive intake the tent has because of light leak.

Ranges
Temperature: 70 - 75f in the day, and lowest 68f in night.
D/N shifts: 18/6.
Humidity: 60 - 78%, usually averaging around 70-72% in the daytime.

Germination
Seeds in water -> Paper towel -> Jiffy pellets until the first set of serrated leaves appeared.

Yesterday I added the germinated Jiffy pellets (with mesh) into a 1.5L fabric pot with Biobizz Cocomix + ~20% Plagron perlite. The coco was pre-flushed with normal tap water, buffered with 7.5mg CalMag/gallon for 8 hours and then flushed again with 6.3pH distilled water to get the EC to under 100. The runoff pH was ~6 after the final flush.

Before transplanting I was watering lightly with 5.9pH water. Yesterday I transplanted the Jiffy pellets into the medium (making sure the medium was moist and not soaking wet/damp) and I am now on day 3.

I have one concern, the bottom left Fat Banana seedling + bottom right Quick One seedling are starting to look light green/yellow down the centre of the serrated leaves - any advice on what this could be? Am I being overly paranoid or is there something I need to address? (the Quick One - bottom right image on its own is a little blown out as I used the flash).

Other than that, how are you guys!

Looking good! The one thing I always say to new growers is "patients, patients, patients!! Let them work on there roots(which is what she is doing!) first! :smoking:

Thanks man! I will try and post progress pics each week as a journal.

Looking fine. All they need is you to smoke a doob and chill. Patience is sometimes the most forgotten tool and the hardest one to master.

Good start!!!
You may be running out of room later with 4 plants in a 2x2...
Good luck!

Thanks! Yeah, my idea is that I want to grow these for 1.5 - 2 weeks, and transplant the 2 strongest to their final 20L pots. The other two I will keep in the smaller 1.5L pots and see if I can get anything out of them. Do you think this is a good plan, or will this affect the stronger ones?

I have been doing a tonne of research online about EC/PPM for water. Unfortunately RO isn't an option for me, so I am considering either distilled water or tap water. My initial tap water reading is around 200PPM and 8.3pH. I leave my tap water out for 48 hours to dechlorinate and luckily my water isn't treated with chloramines, but it is treated with chlorine and chlorine dioxide.

Can I use distilled water if I supplement that water with CalMag and nutes to the desired PPM, or is it best to use my tap water and feed with nutes but offset the required PPM with my tap water's PPM? For example, if the PPM of my tap water is 200, and I need to feed ~400PPM to start, should I only add 200PPM of nutes to bring it to 400?

Haha, unfortunately I don't have any right now hence why I am growing some instead. Gotta make the most of the quarantine!

Distilled water for a whole grow would pay a good part of a cheap Amazon ro water system.
Cheapest ones are around 150$ US.
That's what i did as my well water was around 350-400 ppm.
After the ro system install,well water is now about 15- 20 ppm.Not perfect ro but damn close!

RO water would be ideal, however with the situation I am in I unfortunately cannot install one. However, I am incredibly lucky to be able to buy distilled water very, very cheaply and it's available within a 1 minute walk from where I live so I don't mind absorbing the cost.

In that case, would distilled still be ok to use? I have found conflict from answers online with some saying it's fine and others not recommending it. It's left me more confused than informed if I'm honest!
