New plants curling under and turning yellow

Hey I am a new grower on my first time. I am gonna give a brief history to fully diagnose.

Started growing, just set up 6 26w 6500k CFLs and just moved them into place. Used miracle grow soil and I used some random all purpose plant food found at the local hardware store. About the same time I moved my plants closer to the lights (which I dont think is the problem) I fed them. I made some really dilute mix and they started curling under and turning yellow. Is this over/underwatering, too many nutes, or a pH problem???

Only reason I mention miracle grow potting mix is b/c I heard some people say its not the right pH and if it is the pH how do I test and/or fix the problem

Soon response is appreciated so I can fix my little ones asap

I'm not an expert , but from what I have seen those plants look about normal to me. The droopy leaves can mean either too much water or not enough water , :confused: the only way to be sure is to get a moisture meter or just feel how heavy the pot is. They say the maryjane likes to go dry between watering , and that OVER watering is one of the major mistakes new growers make. Do not rush to adding more nutes , especially in this early stage. Make a humidity dome and put a plant or two under it and see if it perks up. Good luck.

Thanks, I am going to try and let them go a little dry in between watering.

>>>Is is true that I see you can add a little Hydrogen Peroxide to get the roots some o2? Please let me know a definite yes or no cause I don't want to kill my babies :(<<<

It is very possible that I overwatered b/c I would water daily until a little water seeped out of the bottom.

I also nuted them at the same time so idk really, just kinda nervous and want to know how to get those little suckers green and perky again. Atm, the leaves are dry and one little guy is curling much worse

Pics to show the curling and in the last the funky purplish coloration on the underside of the leaf.

Well usually you'd have an answer by now but eveyone seems to be busy???

Im no expert so I cant give you a definate answer but maybe a few pointers.

As they are so young I dont think you should be adding nutes, I would flush them with plain water asap, then let that soil dry out a bit b4 watering again (the wilting looks like theres to much water in the soil) Your soil maybe a little high in E.c already does it say on the bag???

Next check the ph of your water/soil. Youll need a meter or some test strips for your water and it should say on the bag what ph the soil is. I start with soil thats ph7 and adjust my feed to 6.5 right the way through for my crops and dont really get any problems.

And finally make sure they have plenty of fresh air.

Im sure someone will add to this post soon enough, till then good luck dude.

As an afterthought get a good book.

When I started growing I relied heavily on The Indoor Bible by Jorge Cervantes but there are loads out there otherwise.

How not to grow dope
permalink

  1. Decide while stoned to become a weed baron
  2. Plant leftover bagseeds and go looking for lights
  3. Try to steal neighbor's floodlights, burn fingers, go to plan B after healing up
  4. Buy incandescent halogen lights at OfficeJerks cos they look real bright and one blacklight over at the head shop cos it's purpleyness is cool as fuck and makes the Jimi Hendrix velvet poster glow something wicked
  5. 4 out of 72 seeds sprout, fuckin ace!
  6. All 4 get stretchy, fall over and die
  7. Put the black light a little closer to cheer it up
  8. Smoked the dried out seedling, gave me a headache, so I planted some more bagseeds
  9. Dug out Uncle Bob's marijuana grow book from 1972, marveled at nail-thru-stem technique for improving potency
  10. 9 out of 147 sprout, fuckin ace!
  11. Put a pound of nails in salty water to get em good and rusty
  12. All 9 get stretchy, fall over and die
  13. I figured they wasn't getting enough light, so I stole granny's big ole heat lamp and a couple of headlights from some passing cars (damn they're hard to grab at stoplights)
  14. Planted more seeds, put more bullshit and a couple of dead fish in soil mix this time (hey it worked for the Indians and the Pilgrims)
  15. Neighbours complained about the shitty fish smell, I told them to rack off, so they called the cops, who confiscated all the 'evidence.'
  16. Saw story on Fox News about wicked intarwebs sites about marijuana growing warping kids brains, figured I wasn't warped enough
  17. Found pot growing website, figured I'd do a big favor for all those newbie idiots who'd never planted a seed and show em how to do it
  18. Typed Uncle Bob's entire 1972 Yippie Underground growbook into the pot growing website, waited for praises to flow in
  19. No one said nothing, so I typed it in again IN ALL CAPS SO THEY COULD READ IT BETTER
  20. Decided I'd hang around and learn something, there's this guy who says his friend's uncle's brother in law once knew a guy who grew like POUNDAGE in an old refrigerator
  21. Stole a refrigerator and put all my halogen lights in it along with a 5000 watt security light I found on top of a football stadium
  22. Planted 693 more seeds in old coconut shells and put a half a box of Miracle Gro granules on each one
  23. One sprouted and it screamed at me to kill it before it had to spend another second in that damn fridge
  24. Gave up tryin to be a weed baron
  25. Got stoned again decided to put the Arabs out of biz with a car the will run on leftover Mountain Dew
  26. Broke into a vending machine and stole 900 cans of Mountain Dew
  27. and so on...

Im using MG soil and also having the same problems. I suggest a different soil thats not full of so many nutes.

Hi,

I don't want to take over this post, but I am having a similar problem. Any additional info would be appriciated.

3.5 weeks into flowering, lots of yellowing at the bottom fan leaves, and severe claw. Here's some pics. Hydro, ebb and flow, 4 waters per 12 hours of light, standard organic bloom ferts with big bud added. Good PH. Low temps af 63 at night. Thanks....

MG soil has nutes already in it. they don't need any extra.

drooping can be from too much or too little watering. Just make sure top of soil is dry be4 watering. [ not too dry though]

They yellowing is not from how much you water. It's usually nute burn or somethings lacking like iron, calcium, or something else.

My suggestion is not to use MG. I had some plants in MG and the leafs curled up and turned yellow. Not to mention it feeds them for like 3 months and its hard to add your own nutes or know if the plant is getting what it needs.

hahahah it is worse. i check on mine ALLLLLLLLLLLL the time, its horrible. these plants have given me ocd. what i'd do man, is it looks like a watering situation, i'm not pro, but just from looking around on here, thats what im thinking. so, just let the soil dry out, see if your new sprouts start looking okay and give it a little water. let the soil become dry or feel/look dry before watering again. its important to water, but too much hurts too.
