They dont seem to grow.I need advice from the more experienced.

Hi fellow growers !!



After many years i decided to grow again. I bought 4 seeds, and on 5th of novenber i had them sprouted.



One of the seedlings (northern lights)is really not growing, is pale and shows interveinal chlorosis.



So my info



I grow dwc



I use flora series trio



Temps in reservoir are 17 to 20 celsious.



Ppm around 900



Now about ph



I was moving from 5.2 to 5.9 i know 5.2 is low. For the last 4 dayz i am near 5.8.



Oh this seedling is under a 150w laputa ufo grow led.50 x 3w leds. I keep it 20 cm over the plant. Dunno actuall wattage and thats my first grow with leds from seedlings. I got another laputa over the og kush and i also got a galaxyhydro 300w over the ww and critical kush which i keep at 55 cm .



Temps are 22 to 25 w lights on and 17 to 19 w lights off.



Humidity around 40 percent.
I think thats all

Feeding too much will not cause them to grow faster. Ufo lights are weak so so not expect super fast development.

Also seed starts are slower.

I had grown with cfls and i know for sure that this light cant be wweaker than cfls at least for that stage.So the weak light assumption is out of the way.
But is my feeding too much ? The GH feeding schedule says i should go 1000-1200 ppm.I did less than that cuz i know less is more.
So my tap wwater is 215 ppm
what would u suggest my totall ppm should be at that stage ? we are at week 4
Thx

Your total ppm shout be about 7-800 at this point. Those are severely underfed. Set pH to 5.8 and feed those girls!

800 at 0.7 conversion that is ?

700-800 ppm?
but my readings are near 900 .

900 @ .7 scale, and are you including the 215ppm of tap in the 900? so 685 of nutrients and 215 of tap?

id say you can bump it up to 1000ppm of nutrients & 215ppm of tap for an overall ppm of 1200ish and you should start to see them turn around, you can probably go hotter and not have any issues, but i do not use the nutrients you referenced so im not speaking from expierience.

The GH feeding schedule is probably stating PPM values in .5 scale.

This should help you figure out your feed.

Y i got the chart
Yesterday i followed someones advice and i dropped the ppm. So i will check out how it goes and if lowering ppm was the wrong way to go i will start adding more nutes. By tonight that is .
Thx alot my friend
