Are these seedlings about the right size?

Are these things the right size. Planted beans on the 11/30, they popped on 12/6. So they are 12 days since popping open...
Any thoughts would be great.

G13 pinnaple express #2
Blue OG
And heavyweight seeds fruit punch.

All germinated one fruit punch runt.

2 other clones in here as well.

They look kind of small honestly.. how much light are they under? My plants were started around the same time and are all between 3-5 nodes tall and have been transplanted to 1 gallon pots.

Also starving for magnesium.

Day 17. I have trimmed off 4 fan leaves so the under growth could develop. It's a thunderwookie from bodhi. It's been in this 5 gal. bucket since day 10. Grown under 6500 k t-5s. I moved it under a 400 watt hps today to start flowering it. Loves my worm casting shakes.

Damn. I'm doing something wrong. They're only under 100 W of T fives. 6500 K.
NO3 306ppm
NH4 25ppm
P 51 ppm
K 218 ppm
Ca 165 ppm
Mg 83 ppm
Fe 2.5 ppm
Zn .7 ppm
Mm .7 ppm
Cu .02 ppm
Mo .006 ppm

Been waiting on more mag sulfate to bump ppm up to 100.

Could they be slow because of lack of light and magnesium.

I am getting 2. 6 bulb 325w t-5 6500k fixtures on Thursday.

Put them 1 inch away from the t-5 fixture with a fan that barely makes the leaves twitch. Been doin this a lot of years and I prefer soil over hydro. I would go with a 400 watt hps for flowering. Should be about the same price as one of the 6 bulbs t5 fixture.

What do you think about HPS vs the Fluence vypr plus LED? I was thinking either 2 600 hps in a 4x8 or two vyper plus fixtures.

For me I like hps

I’m having a hard time believing that your plants are that big at 17 days from seed.

I just poped some more seeds. My two 325w t5 fluorescent fixtures will be here on Friday. I am going to also vertically alternate 300 W LEDs (180 watt actual) On two sides of each fluorescent fixture.

I germinate with my cups on reptile heating pads with a styrofoam cup inverted on top to insulate. 6 bulb T-5's are the bomb for young plants keep them 1 or 2 inches away with a little fan AS SOON as they sprout. They are 6500k which is what you want for vegging young plants and clones. Run them 24 hours for the first 2 weeks. I start in 20 oz solo cups filled to the top with high quality soil. Your cups look half full LOL. Maximize your root zone. What is your temps? 80 f is optimal. They should need to be transplanted in 10-12 days. I use worm casting shakes on seedlings. I keep them moist but not soaked. I water a little everyday. After I transplant to 5 gal. buckets I continue to use the t5 until they are about 10 inches tall and again 1 inch away. This helps with transplant shock and the roots love the t-5 spectrum as well. What you see is what happens when quality genetics is combined with a skilled grower. I don't think i would like growing in that stuff your growing in nor do i think beginners should start out with hydroponics. Good Luck and believe it rookie.

Stack something under them or make adjustments so that they are 1 or 2 inches away from the t-5's. I think your light is to weak and too far away. You need to step up your game before you mess up some more seedlings.

The beast at day 20. Removed two more fan leaves since last pic.

How tall are your plants at day 20?

Get them closer 1 or 2 inches. It's ok just don't let the bulb touch them. Make sure the leaves twitch a bit in the breeze. I use a 4 inch fan that blows air down the length of the fixture. The beast has earned sole possession of 400 watts at day 21. It's been flowering since Tue. so it has stretched a bit too. 13" tall 22" wide. You should notice a difference in them in 12 hours. Like growing. You might need to transplant those bigger ones into their final home so your roots can start stretching out and taking in food. Those cups are only for the first 10-12 days. Having them this close to the light is going to put nutritional demands on them. Also it's cold on the floor they like to be warm. Room temp hi 70's or 80. You also pruned WAYYYYYY to early. Let them get some size on them first. I hope you have a little drainage hole in the cups bottom.
