Crispy, Brown and Stunted..PLZ HELP!!

Here's the info
DP Oasis in soil.
Plants are 35 days old from germ.
They received no ferts untill they were at the 2nd node of true leaves. I gave them 25% strength general plant food...Miracle grow.
They were in small pots 3-4 in. untill 1 week ago. I used a moisture meter they were not watered untill the soil was good and dry.
I noticed the older leaf tips turning yellow then brown, spreading from the tip towards the stalk.I did some reading and thought I had a Mg prob. I began foliar feeding epson salts, untill the soil dryed enugh to feed some epsom salt in the water. It had no effect. This began when they were about 2 weeks old.
They have been under 4 foot flureo tubes 24 hours a day.
The temps hover around 80 F and a 55-60% humidiy.
They are now in 2.5 gal containers,
with a mix of Miracle grow potting soil, Dolemite lime- 1/2 cup to 2 gal soil, Peruvian Seabird Guano about 6 tablespoons of pelletized guano per 2 gal of soil. The PH of the soil is 6.5 to 7.0
I use tap water for watering.
They are 8 plants, the 2 in the pics are the largest 2. They are all undersize to be 35 days IMO.

They blight continues to climb the plant, with new growth outpacing the blight.

I'm concerned that even if they do survive that they are going to be hermies. I just want 1 good female to clone.

I have a 425 HPS, but have been hesitant to put them under untill they get healthy.

PLEASE HELP...I've read and read, and I can't seem to come up with a solution.

Thanks in advance.

Welcome noname.
This will happen.
The plant is using up it's stored nutes.

Don't sweat it.

The plant is regenerating.
The lower will die to make food and room for the new upper.

Happy growing

Oh Yeah cut back on the light slightly,
I would go 18/6.
They seem to start new growth more often with a lil dark period.

You also need as much intake and exhaust ventilation that you can get.

I don't know about that midgrade. The only time my plant ever looks like that, I've done torched it with some sort of nutes or something. He has miracle grow soil which I'm assuming has some sort of nutes in it. Added guano to it and then put miracle grow nutes on it. Oh daddy. When was the last time you watered?

SmokerE,

I used the liquid nutes when they were in the smaller containers, and only after they showed signs of the blight. I thought they were ready for nutes, as they were planted in a plain potting soil w/o any nutes. In other words they were showing signs of yellowing before they got any nutes at all. They have been yellowing and browing since they were about 14 or 16 days old. My thoughts were that they were deficient in SOMETHING. But everything I've tried hasn't worked.

Also, these plants are 35 days old and they are only 2-3 inches high. Why are they so stunted?

With nute burn almost every leaf tip will turn brown and then appear to be burnt.

The yellowing, drying and then crumpling is necrosis.
think of it like a snake shedding it's skin.

You could combat this with advanced nute maintenance.
It will still happen anyway.

Smoke has a good point.
The more I look at your pics the more it looks like N burn.

You should flush with water only for your next water or feedings, and cut back on your nutes when you start back.

Make sure when you do use nutes that you do not pour the nute water soulution on the plant leafs.

Kinda looks like nute solution splashed on the leaf tips.

Just wait around, let one of these old head growers tell you what's up. No offense old people

I had a very similar problem and it was definitely MG def., how long did you use epsom salts for? Did you put it in their water or foliar feed them? I ended up flushing with Clearex by Botanicare and putting it in the water. If the roots lock up, too much salt then you have to try and do it foliar feed, or flush it with something that will get rid of your locked up roots. I'm no expert and it might be N def, they look similar at times. But try foliar feeding them the Epsom salt, 1/4 teaspoon to a qt. And make sure the lights are out, it took me a good week before they started to show signs of recovery, are the newest parts of the plant still getting burnt and crispy? Like I said I'm no expert but it looks like it could be Mg def. Are the veins in the leaves still green? I'm not really sure though because for 30 some days they are really stunted, I have two week old plants bigger than that, so chances are the plant is not getting something. And another thing, I used some MG potting soil and they looked like yours. What nutes are you giving them? What kind, how much and when.

Well the browning leaves are nute burn where you've poured the feed in and it's hit against the leaves, under hot lights this burns the leaf. The reason they are so small is because of a ph problem. Your plants are not taking in the nutes because they are locked-out.

Sorry, only looked at the pic's. What medium, and what ph?

They are in a mix of Miracle grow potting soil, I added Dolemite lime, and some pelletized bat guano.
The PH is about 6.8

I don't think it's nute burn, because it began when they were still in the orginal container, in potting soil w/o any nutes, before I added any ferts.

Must be the MG soil. this shit holds a lot of nutes. You say it started before you added any nutes, and with normal ph, this is very strange.

When you measured the ph, are you talking about the feed or the actual soil?

But this doesn't matter if it started before you added nutes. It can only mean that the nute make-up of the mg soil is too much for your plants. They don't like it. a lot of growers experience problems with mg soil. It doesn't really add up in my mind, but it's the only answer left.

The symptoms started before you added nutes. Was the ph fine before you added nutes? Something's missing here. Have you got a soil ph tester?

I moved the cracked seeds into "plain" potting soil with no nutes, b/c I was afraid the lil' darlings would burn. I have a ph meter with a probe for soil, and also a kit with drops to test the water. The PH was always in the good range 6.5-6.8. I'm a novice, but I've read everything I can get my hands on, and I can't figure it out. They were rootbound for about 1 or 1 1/2 weeks I think, which my account for the size, but not for the leaf problem...

Ah, I think we're getting somewhere. root bound. Did you slice the bottom of the roots to allow them to grow into and fill the new container?

If you haven't then root bound means they will grow very slowly and most likely just strangle each other more when they do grow. If your plant is rootbound and you transplant without slicing the roots the plant will grow only as big as thwey would have in the original pot.

You need to take it out and slice the roots. wait till the soil dries out good first.

Ok, that makes sense. Do you think that the root problem would account for the problems I'm having with the leaves? I guess if the roots are strangled, it would have a hard time with nute uptake, and cause a deficiency. This is logical I suppose.
Let me ask another quick question...

As stressed as these plants have been I'm going to assume they will be Hermies. If I take a clone of an all female branch with no male flowers, will I be able to clone only females, or will all the clones Herm out as well?

Thanks SOOO much...

Yes, just slice the roots and you should see an improvement within days.

Why would they be hermies?

No, if you take even a fem' branch it will still be a hermie if you clone it.

Stop feeding the plant tap water dude.....almost killed my mother, because the water is sooooo hard where I am...Went to rainwater exlusively!
