ALright, I hit them with a dose of my veg nutes, its 6-4-4. Now it wouldnt turn the leaves back green right?
It might. Usually an "aw shit" drill with cannabis is here to stay. Look at the new growth for feedback to see if you're on the right track.

Good luck,

Hi UB, the plants that I posted up in the last page still has a problem, Its post 235. Its gotten a bit worse, with some of the newer growth being affected. You said either mites or nitrogen def, but it cant be spider mites because my other plants have not been affected. I have it a extra dose of veg nutes also, its 6-4-4, and I dont see an improvement. I havnt done anything differently with this one than with my other ones that are coming out well. Any other ideas? Thanks

OneHit, as you know there are all kinds of cultural reasons why your plant is showing stress - nutritional, watering, temps, insect pressures, etc. It's anyone's guess who does not have the privilege of observing your practices on a day to day basis.

Another thought.....many times when there is a problem with the top it's because there is a problem with the bottom, the roots. I'd pop that problem child out and check on the health of the rootball. It won't hurt or shock the plant at all. Just slide it back in.

Casper23, glad you enjoy the thread.

Later......

UB, I took a closer look at the soil, and they def have bugs in them. They are tiny white oval shaped things, very very small. Could this be it?
My other plant with no problems also has bugs in them, but they are little white worm looking things, a little bit bigger, but very small also

Could very well be, most likely fungus gnat larvae, perhaps Springtails which will jump when you water. Did you pop the plant out and inspect the rootball? Just do it. Look for insect damage, soil structure (is it in a state of decay). Smell the rootball, it should have a fresh earthy smell, not a sour or off smell like your grandma's marching boots. The roots should be white or beige in color.

Hopefully someone can help me.... I went to check on my plants that went outside alittle over a week ago, when I moved them outside I switched the cups they were in(Not important why) and because im a retard and was moving to fast I didn't poke holes in the bottoms! . They have been in Beer Pong cups since seed for about 3 weeks now total, they were under CFLS for the first 2.
So my question is alittle over 1 week in a beer pong cup with it raining every other day do they most likely have rootrot? I haven't watered them since they went out but its rained ALOT and I seen they had been looking overwatered lately. If they have root rot what can I do to fix it if anything? I poked holes in the bottoms and im going to let them dry out good before I water, can they pull through? Other than the dropping leaves and stunted growth they look healthy, they might have just been overwatered because its been nice and hot out when its not raining so the soil may not have been super soaked all the time. Any help, please.

You will most likely lose them due to root rot and the fact that they weren't slowly acclimated to sunlight. Roots gotta have air amigo.

Good luck,

Alright no biggie really, its only the 2 out of 50. But I don't think not hardening them up to the outdoors really hurts them, after 2-3 weeks indoors I put them straight outside and they always show good growth over the first few days... never had a problem with that. But with the root rot, once the soil dries out can I tip the cup upside down and slide the root ball out and check for it? I've never seen it before... Does it look like moldy roots or something?

my girl is wilting and getting worse everyday. I am not sure what to do. As the pics show, the fan leaves are drooping downward. the leave tips around the buds are folding up and in. I do not know what to do next. Some of the posts I have read said something about leaching but I have no idea how to do that without killing the plant. She is in a 3 gal bag and the bottom is still very moist to wet but the top 4-6 inches are completly dry.

Pop the rootball out. Roots should look white to beige with good turgor, not dark brown and limp.

hey ub. i've got a problem with a few of my plants and was hoping u could diagnose it for me. i suffered root rot last grow. i sterilized and started over from seed. i'm growing in pots with perlite with a pump feeding them twice a day. i regularly check ph and nutes. temps are 15c-26c. reservoir temp was 17c but i've just (today) installed heaters to keep it around 22c. humidity varies from 25-65%. heaps of fresh air. lights about 50cm from canopy. i've been using same nutes as always but started using dr hornbys big bud and hygrozime this grow. i am using cooltubes for the first time which has cooled the room considerably. outside temps have been very cold lately. i had a big bud plant with a few curled under shade leaves. suddenly one day all the leaves were cupped. i hacked it because i found a few suspicious looking balls on it earlier. suddenly a few other plants (all different strains) have begun doing the same thing. these plants seem to be growing more vertical than the others. the buds aren't fattening or as smelly either. i've read up on ur causes of this problem (leaf curl) but i don't seem to have any of these causes. i use polycarbonate roof sheeting as my drainage tray. a mate suggested this may be breaking down and poisoning the plants. another mate (a plastic injection moulder) said this was improbable because its u.v stabilised. its stressing me out. i've been growing for many years without a problem suddenly i cant seem to get it right. i am hoping it is just cold reservoir temps and i've already fixed the problem. please help. i've attached photos of healthy and affected plants. i've posted in this thread because moisture stress seems like the most common cause. cheers

"Suddenly" means they reacted to some kind of change. Your call.

i hacked it because i found a few suspicious looking balls on it earlier.
What kind of balls and where were they located?

suddenly a few other plants (all different strains) have begun doing the same thing.
You must backtrack your steps and see what has changed. If ALL culture has remained the same then you may have insect or disease pressures.

I have never known polycarbonates to break down under your conditions.

Suspect - "but started using dr hornbys big bud and hygrozime this grow." At what rate, when, and what's the total NPK value of what you're giving your plants? I suspect your plants are reacting to a salts issue.

Good luck,
UB

UB, what do you use when your facing with a major bug infestation? Particlarly ones that feed on the roots and crawl around in the soil

If harmful, like fungus gnats or perhaps Springtails, a drench of Orange oil or malathion works great.

Flush the pots if indeed you overfed. Feed them according to their size and vigor. Your call.

Good luck,
UB
