2 week old seedling need help

here I am at around 2 weeks and as u can see the two bottom leaves are starting
to yellow and the rest are drooping. Nitrogen or pH deficiency?


just a little info about the environment:

fox farm happy frog soil medium mixed with a little pro-mix
it's been going 24/0 1 26w cfl a room temp of 75f.
no nutes have been added yet. But I have maxicrop liquid seaweed 0 0 1 and earthworm castings 1 0 0
put a tiny bit of dolomite lime spreaded ontop of soil.
water has been as it's needed.. when the soil feels dry about an inch down.

I've been watering with tap water that I let sit out for awhile but obviously that pH is too high
so I went out and got this which is 5% Acidity


How much of ^^^ should I add to a 32fl oz spray bottle for 6.3-6.8 pH ?????

I went and got some pH testing strips from home depot and their shit. It says that fresh
tap water out of the spicket was like at a pH of 6 according to the colors...

You're way better off getting a digital pH pen... you should be checking the pH of your water/feed solution everytime...
A pH of 6 is a little LOW... in soil, you want more of a 6.5-ish and in hydro/soil-less you go for more of a 5.8-6.0
And you need to get some pH up and down... I've never used vinegar as a pH buffer before

As far as your plant... It almost looks hungry to me... try a very light feeding

should I spread some earthworm castings ontop or mix some liquid seaweed in some water ?

You are using nutrients. The soil contains nutrients, as do the castings and seaweed.

Just use plain water.

Seems like a classic case of over thinking it.

Change the light schedule to 20/4 or 18/6. There is such a thing as light saturation and it is bad for plants. People seem to think that cannabis not "needing" a dark period means that 24 hrs of intense light must be good for it.

Watering "as needed" can mean a lot of different things. "As needed" may be way to much. Is the soil drying out within the first few inches of the pot? Is the pot light when you water?

Give it some plain water, chill out on the light schedule and leave it alone for a week.

I only add grandma's unsulfered molasses to my water when feeding their first four weeks of life then when it starts to flower add more P to your water and even a little N. I use shultz bloom plus 10-54-10

Ive always thought that drooping of the leaves is due to over watering. This being because the weight of the excess water in the leaves is too much from them to hold up. Not sure if It's the case, looks a little low on N as well, could be either of the 2

You have nutrients in the soil and a cannabis seedling needs next to nothing. I usually leave mine on plain tap water the first 7 to 14 days of their life. My tapwater ppm is about 200 mostly cal/mag. My guess would be your nutrients are locked out because your pH is to high. Tap water often starts around 7 and can run as high as 8!

Get a pH pen and check your water's pH. Anyway that's what I'd do and I'm a newbie too and I grow hydro! LOL So you may want to wait for the grow gods to come along but that's what I'd do.
Good luck to you.

MG soil has tons off additives in it, your seedling doesnt need anything besides some domolite lime. Def a ph issue, like said above feed plain water at 6.5 with a digital pen (well worth the extra money). Ive been using the liquid drops and its alright but its still a guessing game with it.

the son of bitch got worse from last night.. tried to add a few drops of the vinegar. clearly went wrong
need to go out and get a pH pen.. anyone know where ?

amazon just got mine 2 days ago, 3 day shipping

and don't use household items to ph up and down. Doesn't work the same if you don't have a ph pen. and it's only a temp fix

I've been using ph Up and Down kit that I bought on Amazon and it's been working fine. Paid under 20$ I think.
This is what my plant looked like at days 12-13 . the soil is FF Ocean Forest. Happy frog has enough nutes in it for your plant for couple of weeks . what's your RH ? I know you only have 1 bulb on it but I've been told that taco looking leaves are heat related .

lmao ! found out i was feeding my girl water that was pHed at 4.2 after getting pH pen hahaha. got some pH up & down. guessing that was the problem

i have a similar problem with my 2 week old im thinking i have ph lock out.
