Hi there, just started my first hydro grow, and am right now sprouting hawaiian haze x plum from seed. It's been about 5 days since it first popped out of my rockwool, and has been growing relatively consistently day to day under a 400w MH @ ~3.5 feet above. I am slightly concerned however as it seems like the stem is getting a bit wobbly, and the cotyledon seems to be drooping. (see pic). Am I all good, or is my seedling suffering / what can I do to remedy it?


Thanks guys, great boards, and tons of awesome information

Sorry, don't know why the image uploads on its side...

It is stretching for the light. When you transplant it into your new medium make sure to bury it down pretty deep to the the stem is covered by the medium (hydroton,etc) . The light should be moved slightly closer during seedling stage

Looks on track

Extra stretching is normal when starting from seed.

seedlings dont need much light to get goin; I use 1 regular bulb, or 1 CFL til they reach some serrated leaves.

Thanks for the input guys, I just switched over to a 100w equiv cfl + reflector ~ 2 inches above

Thats perfect until your ready to put it in your new medium. :thumbsup:

keep us posted.

Put a small fan on that lil one to create a MILD breeze. All you want is just a lil "wiggle" from the plant. The gentle rocking back and forth will help strengthen the stem before it becomes top heavy and starts going in the wrong direction.

looks great I agree with tiny little air flow will give it some stregnth.

Just thought I'd give you guys an update (see pic) :-)


I am having some brown spotting issues in random places across the plant though and I'm not sure exactly what's causing it...

It seems like its either light burn or mg deficiency, but my reflector is ~18 inches above the plant, and I added some epsom salts when I fed it, so I'm not sure... pH is good at 5.5 (calibrated test)

Should I dare say it guys...SHOULD I???

CAL-MAG SHALL BE YOUR SAVING GRACE SIR!!!!

Picked up some calmag+ today, and added about 5ml/gal. I'm going to change out the water/ refeed either tomorrow or the day after anyway, so we'll see what happens

Here's a pic of a really bad leaf near at the bottom of the plant.

Could this be a phosphorous deficiency? Some stems do seem a bit red...

This isn't really representative of the rest of the plant (see above pic) but some leaves look like they're also headed down this road...

Might also be Mg, just dump and start fresh with the Calmag and watch for signs :thumbsup:

Okay...so I think we need to address this here. Adding cal-mag will not fix your old growth. It will only make sure the new growth will not experience the same problem. When possible, take those crappy looking leaves off (they can lead to molds, etc....when you leave them around. Just the maintenance piece of growing.

Cal-mag was the issue...it was locking out all of your nutes...and now you should be fine. Give us an update in a week...If the problem persists. The answer would then be your PH. Some strains like querkle, grape ape, and p kush...always need LOOOOOOW PH levels. 5.2-5.7 would be perfect during VEG! It all depends on your environment, water source, medium, nutes, and strain.

Enjoy your first seedling man...Even my first hydro grow from seed is on here. God damn did I make some rookie mistakes!:D

Good job so far and Good luck!:hippy:

i have a recoomendation for you and your new seedling. once it pops up get the seedling into it is perminate growing pot as soon as possible. your seedling is going send out its tap root. the tap root is the plants first anchor root and if it just curled up under your cube it is the first part of stress in ts bery early life. we all know stress is bad for your plant.
studies have shown that if that tap root is allowed to curl up under neather it is more likely you will have a male plant. so the sooner you can get it into its home the better off you will be. the better off the plant will be. so take a few minutes once you see the seed pop get it to it home right away,
i grow in rockwool using 3 inch net pots filled with aquarium or pea gravel. i soak my cudes in a 25% solution of ces nutes( it has a ph buffer in it to bring my water to 6.5) rockwool has a ph over 8 so soaking it bring the ph down to the recommended 6.5.) i will get the pots ready adding my gravel and cube then fill in around the cube making sure it is strudy and ready to go. i then put the seed in the cube and cover with a dome.
this way if i have a good seed and it pops then it in its perminate home and all i have to do is move it into my system. i never have to touch any part of the seedling again.

WOW MAN...6.5...you are growing some PH forgiving strains. Read up Sir...thats too high from clone or seedling. Even during veg state recommended is 5.5-6.0 (and 6.0 is high for most strains in this stage). If you doubt my expertise in this matter...I suggest you take a look at my projects.

Exactly what he said.

I've always read and been told that 5.2-5.7 is optimal pH range for most plants...

read up some more guys. i am hydro grower and 6.5 is the optium ph for the mj plant to utilze all the necessary nutes we add.if you get it to acidic you will burn your roots. i am not sure about dirt but 6.5 is the correct pn for hydro

here is a chart for you use if you dont believe me wen i tell you 6.5

Great find! But, that chart shows that I should be at 6.5, for soil, and you should be at 5.8, for hydro...

the reason we suppliment cal mag is that a plant needs a 5.0 ph to use it at optium levels. if we lower our ph down that far we block out other more important nutes

if you look a little more at it some of says experiment ph ranges. the company i use adds a ph buffer to their product and it is 6.5. i have to do no adjusting at all to my water it goes to 6.5 it have been working for me for years and i am not going to change it now. but i am just showing that 6.5 is the best ph for soil.
we add the cal mag because if we take our ph down to low we block out other more important nutes. so it is easier to just suppliment the small amount of cal amd mag needed for the plant

BUAH HA HA HA HA!!!!!!!!!! LMFAO! SO RIGHT

LEAFNUBIE...These people have been grpwing before you were a twinkle in Daddy's eye. Think twice before speaking in absolutes and by providing one piece of evidence. PH is relative to the strain, the medium, and nutes, etc. But, you are giving someone bad advice. Not necessary to provide half-assed knowledge.

I am glad you are in college, with friends in prep school, etc. By telling us that you are admitting to contributing to the delinquency of a minor. Bad FORM sir. Your posts are violating the rules of the forums.

And wow sir...When your PH IS HIGH, you can cause lockout...and too low below 4.5 will cause Lockout also. You obviously still have a lot to learn about true hydro growing...and not growing in your closet at the FRAT house.

You need to listen to what these people here are telling you...If you listened, you could increase your yield dramatically. Maybe double it. obviously you are new...and have had only a few posts...and recently started growing (being called on your shit, providing bad evidence that you were firther caled out on...and still falling back on your intial asseration...which was proven wrong by the facts you provided as the basis for your argument). Maybe you should listen to your professors a bit more too?

THIS IS WHAT WE CALL AN EPIC FAIL on your end.

Enjoy your first seedling man...Even my first hydro grow from seed is on here. God damn did I make some rookie mistakes!:D

Good job so far and Good luck!:hippy:[/QUOTE]
is it rookie mistakes or was it the ability to create a stable enviroment to grow. did we add more thinking it would help, did we think moving the light closer would make it grow faster, these are things everyone makes thinking they are going reinvent the wheel. basically we all have the knowlge and we know what to do we just think we are going to do it better.
now that you have found that what is the best way that works for you, you have created that stable enviroment that works best for you. and that is most of the so called rookie mistakes. thats why we have to dial it in so to speak it getting that enviroment stable........i am sorry i cannot stress it enough to everyone even new and old growers alike

Ok I was just gonna stay on the porch and let Marty have fun but oops I fell off the porch. Might I bring your attention to the highlighted part of the statement above. Yes everyone finds what works best for them and apparently 5.2 to about 6.0 in veg is avg and 5.5 to 6.5 is avg in flower. So if everyone needs to find their own sweet spot and the avg in both parts of a grow put you at 5.5 to 6.2ish through the entire grow, how can it be said that 6.5 is THE PH for everyone?? I'll stick with the averages and have less problems. :jointsmile:

ok, I definitely agree I was having lockout from too much Mg, but I also think i was having some serious salt issues, as I just found out that the water in my residence is conditioned, so I dumped and renuted with RO water + calmag, I'm throwing it into flowering tonight, as its about 12 inches now.

Anyway, thanks for all the input, raised my pH to 5.7 too, seems to be growing more rapidly now.
