DWC stunted and yellowing. Why no growth? :(

[Urso hidro]

4 week plant. Plant was becoming yellow on the 3rd week so I raised the ppm to 360 and the leaves tips burned, so I lowered to 320ppm. Using Reverse osmosis water with 1 ml/gallon Armor Si, 2ml/gal calmag, 1ml/gal micro 1ml/gal gro 1ml/gal bloom
Ph adjusted to 5.5 let it raise to 6.2 and lower it back to 5.5. Why no growth?

Do you have a fan blowing on the little lady?

She's a little lady at this point. No need for all the stuff. Just micro and grow will get you going.

Use ec when talking dissolved solids. I have no idea what ratio your meter uses. Ec is ec no matter what meter you use.

Ph 5.8 in veg. 6.2 in flower. Or about in that area.

Also...thats 4 weeks....wtf. you have had issues from the get go. Plant should be 18" tall and bushy as fuck after 4 weeks.

My first guess would be to hot tho.

What lights? What temps? What temp is your water?

Also res temp 66f, room temp 70f rh 60% 15.000 lux light (3000k quantum board)

A seedling like that should still be in a dome.Whats the seedling in?

300 ppm=0.6ec 360 ppm =0.72ec
There is a fan blowing her

In a tent. I could raise the humidity with a humidfier up to 80% if needed.

Id start another seed in a cube while you work on this one if you have one.

Calibrate your pH pen if that's what you're using, and do it weekly. That plant has probably no nutrients available in solution.

That and light distance. Seedlings are very sensitive to light. You don't need much, just enough to stop stretching.

@Failmore also mentioned that it might be to strong sauce, I'm not to familiar with GH dosings(ml/gallon)

My last grow at 30 days.


Honesty pull your res. Fill with ph tap water.

See how things look after a few days.

Tap water has enough crap in it for that plant for now.

No, waste of time.Just cut a plastic bottle to make a dome,drill some air holes.Remove the water and reset.Just a little A and B nothing else.You need some clay pebbles in that net pot.

That little plant is in a tent with led lighting, and the air temp is 70F? Do you have an IR thermometer.
That's probably *way* too cold.

Ph 5.8 calibrated pen. 3.2 ft from lamp. I use a luxmeter 15.000 lux.

I'm not using clay pebbles, only a cloning collar.

Outside the tent is 60f. It is cold here.

Thanks for all replies. I think I will lower the light, see how it goes. Change the water to tap ph'ed if no improvements. Maybe it's just better to start over.

No, I'm just confirming/asking; the air temp in the tent/plants environment is 70F? I duno for sure about all the other possibilities, but that is for sure too cold. If you directly measured the plant I'd expect or guess it would be in the range of 65-68F. It should be 80*F+. The plant, not the air.

A little dome over the plant will increase temp and humidty.Ill ask again what was the seed planted in?

 

[myke]

also what is the water level to the net pot?

OP has the plant in a cloning plug....and that is it...nothing is in the net pot. Not sure if that is a thing people do.
