ends of leaf twisting around? have this showing on a clone. only on 2 leaves.
clones are 3 weeks cut under a CMH 400w bult at 4ft. one clone was 3 to 5 days cut older than the 2nd. Pics are just a few hrs ago.
Happy Frog and just water for the first 2 weeks. 5 days ago they got a water with 1/4 strenth DynaGro Foiliage pro, and 1/4 tesp Pro Tekt in a gallon. both plants shared about a qt that water, they LOOK like they have started to untwist a big.
straight water 2 days ago, and will get another fed water here in a bit.


using my well water. phs around 7.5 out of the tap. not sure on its ppm and breakdown.

So what would cause this type of leaf twist? only 2 of the leaves on the larger girl have it severly, and both have wavy leaves, but only a few of the oldest leaves exhibit this charicteristic. both came from the same mom, who also has this triat/issue. could this be a genetics thing, therefor not really changeable, thus nothing to worry about? im just wondering if what is causing the twist, may also limit growth, size, and/or strength?

Read ALOT of your threads over the last 3 months UB. much respect for your Degree in Hard Knocks. Im in my mid 40s, and still at school, though i think if we are breathing, we should be atleast still trying to learn.

any info/help/recommendations on my "twist, twist" is greatly appreciated. RH is about 25 to 28%, room is 68ish at dark and 78 to 80ish on light. 18/6 lighting.


check mid leaf on left at tip. you can see its actually flipped 180* around.
this is the older girl by 4ish days cut.



here is the younger girl (3 weeks cut tonight about right now at 8:30pm)
you can see the same area that the leaf is twisting over to reveal the underside ever so slightly.


suggestions?
and ty for any i get.

Sheesh, been a coon's age since I visited this thread. Don't know what caused the twist, but I wouldn't worry about it. As long as the leaves are still green and productive, you'll be fine.

Good luck,
UB

I have the plants in the tub with water, (Areoponics?) Anyways, I changed the water not too long ago, but when I picked up one of the plants, there will be like some white stuff on the roots and water would wash it away, (is that salt?) does it mean that i have too much plant food? the leaves are curling, and has some brown spots on it. Help!

Could be mold.

Looks like the root system is toast. Too much water, too big a pot, soil is too tight, not enough foliage to wick the water out of the root zone? It's anyone's guess.

OK so I am currently growing an auto flower russian rocket fuel outdoors. its 20 days old and still no sign of male or female is this bad? Or is it just a slow grower

spyder mite eggs under the leaves would cause dead spots on top of the leaves do to draining energy from the spot its latched on too...they usualy populate towards the middle of the plant...u can see the adults crawling around if you pay close attention....but I do not think thats whats wrong with urs...Im thinking it may be a trace mineral problem..there are secondary nutes so to say that the plants need like calcium, sulfur, and magnesium they ensure highly concentrated photosynthesis to happen, so the growth is good and it developes like it should or nicely.there are trace minerals it needs like boran,copper, molybdenum, zinc, iron and manganese. Only little amounts are needed, BUT they are indispensable to the overall well being of your plants. All these nutes work together to keep constent healthy plant development going bro ;) good luck

hey riu, ran into a little dilemma only a nooby could pull off,

so a little backround- ff of- seedlings 2.5wks- 300+ w cfl.

heres what i did that some of you first timers can learn from...

so i thought i could skip a transplant or two and put my seedlings straight into 1 g pots (against the warning of the local shop owner) my theory being i could just spray them and only water them what they needed, BIG mistake, at about the 2 wk mark my little family started marbling (for lack of a better term) some rusting type spots on some, yellow edges on some and some both, i couldn't for the life of me figure it out(till finding this thread) well long story short i must have nutes/salts built up from not properly watering(enough to drain out and flush out the build up so to speak)

now heres my dilemma, they are still growing BUT-I fear that if I flush them out in these 1g pots the roots wont be able to soak up the water from the bottom of the pot, leaving me with possible root rot, also not knowing how healthy and long my roots are how do i go about fixing this?????? meaning how can i transplant back to smaller pots if its even possible-not knowing how big my rootball's are???

i wanted to start flowering in the next day or two seeing as i am fighting the warm weather in my area (just picked up 596 watts of 2700k)

any advice from you experienced guys, i don't want to lose my 100% indica genetics as all i have left is pure sativa beans, which in turn would take even longer and put my room at ungodly temps should the weather not hold out for me.

am i completely assed out? does this rookie move kill my chances at flowering being done in the next 2 2.5 months?- its a tough way to learn a lesson thats for sure- but goes to show you what trying to take shortcuts gets you..

thanks in advance riu family

I germ and grow for quite a while in 1 gal. pots, nothing wrong with that. Sounds like you don't have your watering technique down pat. Overwatering is usually not a problem if you have plenty of foliage and a healthy root system. It's an issue of the exclusion of air that's the problem.

Good luck,
UB

thank you much Uncle Ben, that was indeed my problem, no idea how i got away with it on past grows (maybe something to do with the beautiful climate of CA.

i narrowed it down to being a Calcium deficiency, mixed up some bone meal and ph'ed it after adding it, all my little ones perked up and the "marbling" is no longer continuing.....

much thanks from the bottom of my heart bud- your a good man!

Hi, I have read a lot of this thread but I would still like an expert opinion before I come to conclusions. These are 2 LSD strains (day 27 veg) which are looking somewhat small and the stems are looking quite weak causing a droop in the leaves. Also, there are a few lower leaves that are folding downwards at the tips. Any diagnosis for these? Im thinking its from underwatering but I am not sure.

View attachment 1589577012.jpg

I water these every 48 hours with about 1/5 gallon of water per plant. I use a 400w hps in a 4x4x7 mylar room with 3 gallon pots where temps are generally 84-86 lights on and 45% humidity lights on 70% humidity lights off. Unfortunately I can't seal the grow room until I get my duct fan in the mail because heat gets in the mid 90s when it is closed off during lights on.

If I had your environment, I'd focus on cooling the room to the high 70's and raising the humidity at least into the mid 50% during lights on.

you need a dehumidifier to run at night and better exhaust.....you could be watering them to much looks like...and im seeing heat stress on the first pic...has the room gotten to 90 or more a few times before? Are these autos? If so they are perfect hight for there age :) What are you useing to move air threw the room??
