LEAF CLAW MYSTERY AT BUD SITE

[lethalrx]

***
background
1. Soil, just got water PH from 7 to 6.5, was at 7 when problem started, cold at night 60, avg 68 to 73 day,plants over two months old, organic nutrients, water every third day, 1000 watts, problem started at 1 week into 12, now after 2 weeks into 12 hours and problem is getting worse in some, better in others and the same in others. almost no sign of mites

i have tried to water less since the first signs. if i manipulate the leaf, try to uncurl them, they will curl upwards, the leafs are still fairly healthy overall, again, this is the leaf families at the bud site

i have been reading everything i can about curling leaves lately, the claw.... i have found people mentioning the possible following causes.

low rh, blueberry strain trait, haze strain trait, ph imbalance, to much nitrogen or other nutrient, nutrient deficiency, over watering, suffocation, cold, ( growing some various haze blueberry crosses / silver haze * bb / hindu * bb )

i guess it is important to clarify the type of leaf curl and where. since there are so many leaf problems and curls, it is at the actual site of the bud growth, the leaves have no real discoloration, just hook over and curl in like eagle claws

so anyone wanne talk more about the specifics of the CLAW

or are their different causes for the CLAW

or is it just ok? natural claw ?

sorry for the pic quality, it dossent show the issue that well
hummm....

I am a newbie on his first grow so take a grain of salt with this advice...

They look great! If growth is uninhibited and there is no discoloration and physical damage is not an issue than I would say that constitutes normal growth...however abnormal it looks. :jointsmile:

I see concrete and cellar insulation? Are you in the cellar? Are those plants on the floor?
Potential problem #1: Cold feet. IF your temps are dipping to 60, and that is a cellar, I'm going to assume that the floor gets even colder and/or stays steady at a temp colder than the room itself. You MUST lift plants up off a cold surface like that. Shipping pallets or milk cartons are ideal. Cold+wet+pH imbalance=dead.
Potential problem #2: Shoes too small Give one gallon available soil space per foot of plant height. Canoed-over leaves are a sign that the plant is pot-bound. Plus when the root mass has overwhelmed the available space, soil chemistry starts to suck big time. You will not be able to control pH as well, since the relatively large mass of living material in the pot is actively uptaking nutrients and water and changing conditions.

Okay. Bigger pot. No contact with cold floor.

like stinkyattic said, if your plants are on concrete get them off of it. that stuff gets cold! only feed once a week in soil. blueberry gets leaf twist not the claw. i'd say you have nitrogen toxicity. i've only had real claw problems when growing sativas.

[klondike_bar]

mine did a claw and died of nitrogen issues, so id watch the fertilizer doses if i were you

didnt see it in your post, so i assume you didnt flush it?

I'd consider fert as well.....and make sure my ph was normal for my soil runoff.

thanks for the reply, sorry for the old post stinky, that was a mistake. anyway...

wow. durrr? the cold floor... it is not a basement, they dont make basements round here. that is the good ol ' garage floor..
however, still probably consitantly way to f-in cold.. so would you say a space heater would work just as well as lifting them of the cement... or they just need to be lifted up ?

the buckets. yeah. the sick looking plants are 6 ft tall and in 4 gallon buckets. i bet they are bound up like no tommorow, i poked some holes tin them to help breathing and let water filter out.

would you say I NEED to change the shoes. what if i dont, will it really have an impact on plant health, yeild, etc. i guess if yoyur the doctor and you say to get bigger shoes i should get bigger shoes, but what do i risk if i am a stubborn punk and keep them root bound for the next 6 weeks untill they finish flowering. ?

Given the choice, lift the plants up first of all. That's very important.
Drilling side holes was a good call.
You may still need a space heater, but first things first.
6 feet tall huh? Ehhhhhh that's a BIG plant for indoor conditions. You need to get them into bigger pots- they WILL double in size at least over the course of flower. Try a large feed-bucket, at LEAST 10 gallons. Or a kitchen-sized trash bin with lots of holes drilled in it. OR a rubbermaid tub. As long as the pot isn't metal.
When you re-pot, use plenty of perlite. This is even more important in colder conditions. Cold but dry is much safer than cold and wet for plants as well as humans.
A slab of that same insulation that's on the walls is fine on the floor to protect them from the cold.

so too much nitrogen and over fert. this is a seperate issue. honestly, i dont know anything about anything and i would say that this may be lending to the problem. is it the problem. i guess all three are problems. floor, shoe size, over fert.

i was watering too much for sure, on this cold floor, cold, too much water. so then the nitrogen could be making them all clawed over like that. I have definately started to water way less.

does that mean i should definately 100% water flush these problem girls out, or use a light soulution. and if i do this, should i go back to regular nutrients after a 100% water feeding cycle.

i will try to check PH run off.

also, if i manage to get them off the floor, pain in the asss, would a space heater still be a good idea during the night cycle.
