3 weeks old and dying please help. (Pics included)

Something is wrong with these plants please somone who knows what I should do I am having a hard time determining if its calcium defficiency or magnesium. Using Foxfarm Ocean soil and General hydroponics Flora Nova once a week. I know its not mites but what is it,

those babies look pretty healthy to me - maybe a little nute burn on one of them. try looking at the marijuana plant problems stickie in the general section to match up pics of problems

Your doing just fine. Looks to me like when you was watering them you splashed a little nutes/water on the leaves? New growth all looks good. I would'nt worry about it keep up the good work! Perhaps that one plant is a light feeder. Try cutting the nutes for just her in half. If the problem persist please update. IMO Much Love.

whats the ph of the nute mix?

Its tap water with 7-4-10 Flora Nova Grow from GH dont have a PH kit unfortunately.

i knew it. most peopl ewith these issuse never have a ph tester. stop the nutes tiil you do. a cheepo is only 7 or 8 bucks ( liquid one)
nutes will usualy lower the ph.
how much water do you give them and how often? also you are going to want to bump the phosphorus up when flowering.

I have Flora Nova Bloom complex for that but I am watering them every 2-3 days when soil dries out for oxygen to roots. I have been nutting every other water so nutting about once a week.

Also I havent sexxed them yet do I have to initiate flowering by going 12/12 they are on 24/0 atm but to see sex do I have to go 12/12 first to see the males/females?

ok, sounds about right. just stop your nutes till you get a tester or it will lock up.
it`s not a burn because most will start at the tips, that is all over kind of, and it`s not splashing the nute mix on the leaves, i do it all the time, my lower ones actualy lay right in it till the mix soaks in. not a problem. it causes problems that way if the light burns the mix into the leaf. thats not the case here by looking at it

18/6 is better. about 2 weeks into 12/12 you will see

how long would you reccomend I go from current state til i switch to 12/12?

get your ph thing fixed then it`s up to you. it depends on your lighting and your hight. let it recover a week to 10 days before switching

3 42w CFL and 1 16w blue/red LED panel Nirvana Bubblelicious is the strain.

i would get on it soon then. you dont have much light power. what is the kelvin on the cfl`s. to be honest with you you`re probably better off replacing that led, sorry but they suck

LED is good actually just not enough of it to do much but add a little light here and there.

have you aver used an hid, if not try it and compare the 2. there is no comparison.
what did your led set up cost?

50 bucks for the led panel but HID vs LED comparison LED wins per KWH if you check out youtube there is a side by side test done. I am only using CFL LED for the small heat and power.

YouTube - LED Marijuana Grow

check out the yield results taking into account that the LED used much less KW then the HID

use what ever works for situation, i`m not knocking you at all. i use a 430 watt hps 52,000 lumens and at 12/12 with a 450 cfm fan at 80 watts to run it and 2 oscilating fans going 24/7 my bill is only about 40 bucks more per month.
equiptment is cheeper, bills aren`t realy that much and the yield dosn`t compare. just something to think about if you intend on going further
