im using fox farm ocean forest and i cant get a pic up because my usb ports dont work
the water im using is spring water and i ph`d it around 6.5 so thats good, it could be overwatering but i doubt that would cause that though the seedlings you yellow
could it be a nitrogen defficency or what?
i dont wanna lose these so the quicker the response the more appreciated lol

depending on age.... it can be nitrogen deficiency

it can also be time for trasnplanting....

it can be different things

If you're past 3 weeks start nutes.. but start at 1/4 strength....... seedlings need watering once every 3-4 days ..... and nute only once a week...
Purple stem you often see at the start.. plus the bottom leaves will die off as upper leaves grow, just watch that it doesn't happen in new growth...... try to get a pic up.... Luck.

the stems arent purple the leaves are and sorry my usb ports are broke so i cant really get a pic up my bad guys
curling down is usually a sign of over watering right? ya ive been watering every other day, is that to much? i have a moisture meter but its a rapitesh one and its a POS lol
im on 18/6 lighting if that matters for like a dry out rate er anything

like i said... it probably need transplanting... you haven't told us what containers they're in.... or what you're using...

so i'm guessing that since you said its seedlings... i would guess you started off in cups... i don't know... but if you still have them in the same small ass cups for 3 weeks.. they need transplanting... thats what happens when you don't transplant... the brown color works it way from the the roots, up the stem, to the bottom leaves.. slowly killing the plant... turning the whole thing brown slowly...

thats my guess...

maybe it needs nutes... damn dude... at least explain your situation a little better so we can imagine it in our minds....

ok... cool... beer cups, 2 weeks ago...

depending on the size of the cup, the roots can take over in 2 weeks... actually, thats around my transplanting time, from small cups to bigger containers... i noticed if i didn't transplant in those 2 weeks, my plants started dying on me... because of the roots... it happened 1 time... i was like "what the fuck are you doing to me".... and i didn't get a response, ha... but seriously, i was going nuts thinking it might be nitro def... but it wasn't... my containers have clear bottom and i noticed the roots were piled up, fighting for space...

so you think it is because it needs to be transplated?
the seedlings themselves are still pretty tiny most r working on there 3rd node with the first and a little of the second nodes yellowing or browning and a few have purple in the leaves and i would guess that to be a Nitrogen defficency.. idk
i sure wish i could get sum pics up so these babies will survive
and ya there in 16 oz. cups with the rockwool cubes right on top, barely even covered by the soil

around the 2nd to 3rd node is when i needed to transplant...

and around the 3rd week is when many people add a diluted solution of nutes... and slowly add more strength each time....

so its most likely either 1 of those 2... but since you already transplanted, i would guess its nitro def... plus its around that time for nutes anyway...

if you're not using something like MG 3 month release for transfers and using soil that isn't high in NPK or doesn't have any at all.... you should give it nutes if its that age...
