1st Grow - Northern Light - Journal (aka help me not screw up)

[KenneyHo]

Starter leaves turning yellow.

Update :

I gave them a flush on Friday, then nothing till last night. Switched the lights to 18/6. I think my fan was blowing too directly onto the seedlings so I moved it. They seem to be bouncing back and the new growth is looking good(I think).

If you see something I’m missing please don’t hesitate to say it! I take constructive feedback well according to my 1st Grade Teacher 🤣

[Canuck147]

Good start - transplanting happening any time soon?

[KenneyHo]

You read my mind. I was thinking about transplanting them into 3 Gal fabric pots this week.

[Canuck147]

Make sure you have some kind of riser underneath - needed for air circulation. I use old bbq grates.

[KenneyHo]

Added a grate under the pots. Thanks for the heads up!

[KenneyHo]

So I just had to order light #3 😳 One of the LEDs has already gone out on my new COB LED. I’ve ordered the Viparspectra 600w as I’ve read good things on it and I see people speak positively about the brand on here.

Day 17 since first seedling broke through the soil. Transplanted into 3 gal fabric pots, except for the runt. Removed the damaged leaves.

Tent: 32”x32”x63
Seeds: 4 x Northern Light Photo Feminized (Nirvana)
Medium: FFOF, Coco Pots > 3 Gal Fabric Pots
Nutes: FF Trio (Haven’t started feeding them yet)
PH: 6.5 PHd water with cal mag
24 Hour Temp Hi: 83
24 Hour Temp Lo: 69
24 Hour RH Hi: 65
24 Hour RH Lo: 50
Light: 23w CFLs for seedling then 800w COB LED ( that already has a busted bulb), awaiting a Vivarspectra v600 600w (260w actual)
Exhaust: 4 Inch 190 CFM w/ Carbon Filter

Looking at the picture with all 4 plants, Bottom Left is 19 Days, Top Left is 18 Days, Bottom Right is 16 Days (she has some early health issues), Top Right is 11 Days.

Tent: 32”x32”x63
Seeds: 4 x Northern Light Photo Feminized (Nirvana)
Medium: FFOF, Coco Pots > 3 Gal Fabric Pots
Nutes: FF Trio (Haven’t started feeding them yet)
Water: 6.5 PHd water with cal mag every 2 days
24 Hour Temp Hi: 82
24 Hour Temp Lo: 73
24 Hour RH Hi: 60
24 Hour RH Lo: 50
Light: 23w CFLs for seedling, currently under a Vivarspectra v600 600w (260w actual)
Exhaust: 4 Inch 190 CFM w/ Carbon Filter

[KenneyHo]

This one is still having some issues. She had the dying leaves earlier that I removed. Leaves curling up and tips drying up. Day 20 for her. Watering every other day with PHd 6.5 water and CalMag. No nutes yet. Temps and RH haven’t fluctuated past my previous post. Thoughts?

[KenneyHo]

Gave them a watering with CalMag this morning. Finally found good use for all of those RW-CDs...LOL!

[KenneyHo]

Picture with all 4; Top Left Day 21, Top Right Day 20, Bottom Right Day 18, Bottom Left Day 13.

A little slow growing but overall things are going well (I think). Downloaded a lux reader app (so take it for what it’s worth) and the readings were; 4,000 Average and 10,050 Max. May start with some 1/4 strength FF Trio next week and will be looking to top the two biggest.

Unfortunately lux readings do not really work with leds. They are not as easy to check as hps/mh etc. DrPhoton can probably provide a better answer to that.

[DrPhoton]

Yes thats right, lux meters cannot be used with monochromatic light sources such as red/blue LEDs. They show a much different reading compared to broad spectrum light sources and so no comparison and or usable data can be obtained from this.

There is also the issue of using lux meter apps which are highly inconsistant due to variable sensors. But also because they lack a cosine correction lens which is very important for off angle error correction.

[KenneyHo]

Redwasp DrPhoton thanks for the knowledge drop!

[KenneyHo]

[Redwasp]

The plants are looking great.

[Canuck147]

They do look great - fabulous color - although I'm just wondering why they are so deep in the pot?

[KenneyHo]

Misjudged the depth needed for the coco pots and didn’t take into account the soil settling. Once I Top and remove some of the lower leaves, I’ll add more soil to right below the “new” bottom shoots.

[Canuck147]

I hate to say it but those roots would have been so much happier with that much more soil below them - that's where you have to start the happiness is with the roots - cuz it's really the first thing they do. More roots = bigger and happier plant which results in bigger flowers.

[KenneyHo]

Lesson learned.

[KenneyHo]

Day 28 for “Nina Limon” #1 . About to top her and one of her sisters. She’s due for a watering. Just gave them 1/4 strength FF Trio week 1 schedule on Monday and wanted to let the soil get really dry before watering tonight with CalMag.

Should I water before topping or after? If you see it, say it as all feedback is welcome!
