Novice grower experiencing problems, possible deficiency.

Hey all!

I am completely new to growing. Purchased 5 feminized super silver haze seeds, germinated them in soil. Using a high pressure sodium lamp,

room temperature = 88 degrees fahrenheit (possibly too hot).

Soil pH = 6.5

Humidity = Low

Water them everyday with 200ml fertilizer solution with increased potassium. The fertilizer has a decent concentration of nitrogen as well.

Exposed to light 24 hours a day.

Fan is on all day as well.


I'm fairly lost to be honest. After doing a bit of research, I'm guessing it may be a nitrogen deficiency but I would like to get an experienced growers point of view.

I've uploaded a few pictures of them. As you can see the lower leaves on both of them have a yellow discoloration and leaf tips on both of them (one in particular) have gone a whitish gray color.

Any advice would be greatly appreciated!

Thanks in advance!

STOP WATERING THEM!

Let that shit dry out man, or there goes all your little babies. They need to dry out, let them dry out, then wait a day, then water.

Ok will do.

I thought that since the room was very hot and dry, I needed to be watering a bit more.

Is 88 degrees too hot in your opinion?

You notice how the ends are white yeah?
Does this mean that those leaves are completely dead and will not repair themselves?

Not only are you over-watering, but you are wayyy over-feeding too. Your babies are still a lil young for nutes. The symptoms that are pointing you toward a deficiency are actually over-fertilization. It's pretty difficult to under-feed a baby.

In a week or two (depending on how badly you stunted your growth) you can start feeding a weak solution (25% or less) EVERY OTHER watering. watering usually takes place every 2-3 days, and in general you only need to feed once a week. once the plants double in size from when you start feeding, you can double the nute strength up to 50%.

For now, just plain water every 2-3 days!

Thanks for the replies guys! Appreciate it!

Is it too late to undo/repair the damage done would you say?

Will this mistake have a dramatic effect on yield/plant height in the future?

Another thing: when you transplant (which you should in about a week) add perlite to your soil. I noticed you have none. this will help prevent over-watering, as well as detrimental problems such as mold and root rot.

So to re-cap:
-Water every 2-3 days with plain water
-In one week transplant, and continue with plain water for one week after.
-start feeding a weak (25%) solution about once a week, ON a scheduled watering day. don't feed in between waterings.

Good luck :thumbsup:

No, it shouldn't have any significant effect on yield or height. the only problem you may have is slow growth for the next few days, but once you correct your watering they will start to shoot up.

Great!

Thanks for the help man!

Definitely lay off the watering for a day and i'd get those things in bigger pots. No nutes till they are about 6-8" tall....even then be careful on the dosage. Always start small and then add as you go along. Some people will say wait till you have 5 nodes on the plant to add nutes.

But if you get some good soil w/ perlite (very important) and transplant those babies....lay off the watering (about every other day, just a smidgen) they will spring back to life.

Good luck man! :jointsmile:

I'm just stating my opinion as you have stated yours....no need to call me out!

I was adding my opinion to help out maxtor101....the more replies that point to the same solution, the better in my eyes! At least then, it's a little easier to know how to fix the problem when several people have the same answer.

just trying to help! :jointsmile:

Agreed, The more people that chime in and say the same thing atleast to me means that the info they are giving is good. I wouldn't question Faddenator's info however cuz he's on the money:thumbsup: Some other people however, to much :jointsmile::jointsmile::D

thanks for the support! :jointsmile:

Ok guys, got a problem!

So, I didn't water them for 2 days. I had a look at them and they were actually looking a lot worse!

I watered them with 100ml today but they are looking very unhealthy now.

I have uploaded a few pictures again, also uploaded two pictures of my setup.

Something occured to me the other day as well. The room which I'm growing in is a boiler room, this may lead to carbon monoxide poisoning. But the boiler appears to be correctly fitted and the output filter seems to be ok. Also I have spent a lot of time in the room, and I wasn't affected.

Could it be the humidity of the room? The room is quite dry and pretty hot.....?

Thanks again
Max

Could it be nute burn from me previously feeding it nutrients?

I had been giving it nutrients while it was a seedling as well....

If you never flushed it after the previous nute burn then yes it could be. When the soil is wet after you over nute the more time you give it to dry the more burning you may see on the plants. If I ever see symptoms of over nute I either flush or if its not too bad Ill let em live. In this case I would've flushed a looongg time ago. I don't know if your girls are to far gone but if they aren't I would avoid allllll nutes and an immediate flush flush flush haha:thumbsup:

There's probably still a lot of nutrients in that soil... did you flush it out? (Flush = watering with 3x the amount of water in relation to the size of the pot)

Your temps are also pretty high, try to keep them below 85. Do you have any other lights that you can use? Maybe a couple CFL's until they start to look better again. Otherwise raise the light, they need a little TLC for the next week or two until you see healthy new growth again.

hmmm ok cool.

So I've started to flush the soil out. I'm doing this by, as you said, watering the soil with 3x the normal amount of water, then presumably empty the run-off water to prevent nutrients being absorbed back into the soil.

Should I do this once a day yeah?

And how long should I do this for?

Also, as suggested before, that I have over-watered the plants. By flushing them now do I run the risk of drowning the plants?

Thanks for all this help, I really appreciate it!

Flushing is mainly to remove salt buildup from the nutes that are left behind.
Also ppl flush once a month although I've heard as much as once a week.

When you do flush let the soil dry out before you water again (stick your finger in the dirt to make sure it's dry knuckle deep), and make sure to check the p
PH of the runoff water when you flush, hope you have alot or big drainage holes in those pots will help you out alot.
Overwatering is caused by frequently watering a plant not from giving it a large amount and letting it dry up on it's own.

If you have 3 gal pots, flush with 9 gallons of water (not 3x the regular amount of water). If you have 1 gal pots, flush with 3 gallons of water, etc. And use properly ph'd water, and check the run-off.

You only need to flush once usually, don't do it everyday. Flushing or even watering everyday will definitely drown the plant. Let the soil properly dry out. Check with your finger or by lifting the pots and checking the weight.

Even though you might be overwatering, I'd say that at this point, it would be more detrimental to let all those nutrients sit in the soil and burn up your plants more. I don't think the overwatering will kill them as fast as all those nutes. Kind of the lesser of two evils here... but something needs to be done. :twocents:

Hey guys, just thought I'd keep you updated. I've uploaded pictures of the plants now and they're looking A LOT better! :D

There are two things that I'm a bit concerned about though.

Some of the leaves have slightly curved blades. Is this due to heat stress?
The thermometer is currently placed under the lamp at the same level as the leaves and it reads 95 F.
I have raised the lamp a bit just to be safe.

Also, I think I may need to clip some of the leaves. As you may notice, the size of the leaves in proportion to the stem and shoot system is huge!

Will this have a negative impact on the plants growth?

Thanks again for the help!!!

Max

Try getting a temp reading so that the thermometer isn't directly under the light. Put some little piece of cardboard or something to shade it. Still, I think it will be over 85F, and most likely the cause of the leaf curl. Try raising the lights a tad until temps are good, and then figure out a way to keep the room cooler. A cooltube can make a huge difference (google: DIY cooltube, you can make it for about half the price)

As for the leaves, leave them be for now. If they are later blocking light from getting to bud sites, you can tie them back or to the side. It's rarely recommended to cut leaves (certain strains are very leafy and may sometimes benefit from this, but it takes some testing and years of growing to find the best method). So, just leave them be :jointsmile:

Ok cool! I think I may position the fan in a more efficient spot as well....

Also, the room in which I'm growing is only about 5 and a half feet high so I need to be able to predict how much the plant will shoot up when I flower it. I've heard from a few people that the plant may triple in height throughout the flowering stage.

I'm contemplating flowering it now so the plant will be roughly 4 feet tall when I harvest.

Any advice on this man?

LST, topping, fiming, scrog... all work well to make the most out of a low space.

Personally I don't like the idea of growing a plant with a single cola unless you have strong lights (1000w's). Tying down and promoting more shoots to grow into an even canopy is much more efficient IMO.

I think if you flip now, you will lose a lot of yield. I'd veg for another month (give or take) and start training them little by little. Then you can maximize your space in terms of length and width while keeping everything relatively low.

The links in my sig all have examples of LST, the last two with LST and Scrog. If you have any questions about the methods feel free to ask in there or here :jointsmile:

your bud production willl be a direct relationship to how healthy the plant is below the soil...and the more root mass(size of pot) the more bud you wil get! then follow all the good advice from above keeping your room a little cooler....78 - 80 ambient is good with air circulating because it is always hotter under your lamps! :smokin:

Yet again I've encountered a problem. Things were going extremely well for the last few weeks, but than in the last two days things have gone downhill. Basically the two plants were very healthy, one was tall and strong and the other was slightly shorter and a lot bushier. Than the bushier one flopped down on all the stems while the taller plant stayed strong.
The weird thing is the stems of the collapsed plant are very rigid and strong but just not vertical.
Please help, any advice would be mucho appreciated.
(As you can see from the photos the plants are into the 2nd/3rd week of flowering)

Ps I know i could use bamboo and prop them up, but I'm more curious as to why they've fallen.
