leafs drying then curling

[LuciferN]

is there anyway to stop it from being root bound like cutting the roots or something as i dont have room for bigger pots

Here is a nice post to solve root bound problem!

You need a lot more light. Low leaves tend to yellow and drop when they are not getting enough light. That does not have the appearance of a rootbound condition, and you have not given enough information for the diagnoses that people are giving you.
We do not know pot size, lighting type, or residence time in pots.
Folks, you gotta know this stuff before telling the man he's rootbound...

A saviour!

This was not really a diagnose, was just trying to figure out... I still have a lot of stuff to learn but I try to help out people over here. I think there was no harm in checking for root bound... Well hope so

Hello my plant fan leafs are drying and curling up its affecting all my plants its starting from the bottom at works its way up some leafs look like they have been eaten! (Attached are some pics)
Humidity bettween 35-55%
Temp between 17.9 and 28.3
Fed them a weeks ago with hlaf specfied neuts (ironic grow and bloom growthtechnology.com) When i first fed them i saw signs of neut burn so i flushed them all.
Run off ph 6.4
Oh and some leafs that look healthy just randomly fall off just like the dried / eaten ones.

Can anyone help me?

Cheers
Tom

You say you are 4weeks into flower? I don't see any buds, you should have some buds after 4weeks of flower(12/12).
Pic 4 sure looks like it is being eaten, not just die off.

E-indoor or outdoor - indoor
E-soil, soilless, coco, aero, or hydroponic - soil
E-specific medium - Grow shop soil with added perlite
CSL-Soil type/brand - grow shop
SCLR-Soil or slab runoff pH - 6.4
E-Water source - tap
E-Source water pH - 7.1
E-Age of plant - about 4 weeks into flowering
E-Type of fertilizer - Ironic grow and bloom
E-Lighting source and distance from plant tallest 4inch smallest 1/2 foot
E-Air temperature (both day and night if you are running a dark period) -17.9 - 28.3
E-Air % Relative humidity - between 35-55%
E-Lighting schedule - 12/12
E-Type of ventilation your room has - 16" ocoilating fan

Do look like they may need to be transplanted actually could this cause this?

Your oscillating fan is not ventilation, you need intake and exhaust to get fresh air into the space. It also seems like you have a big swing in temps. Don't know if this is adding to your problems.

This is just a guess.......but did you feed them again after you flushed them? Have you fed them since? They're not hungry are they? They don't seem big or bushy enough to be really rootbound......they look like they've been sort of hanging by a thread for awhile. That's what makes me wonder about fresh nutes.......but again......strictly a guess. (and I make that guess based on the assumption that your ph meter is working correctly and you have indeed checked the ph on whatever is going in and whatever is coming out the bottom.)

You dont see any as there is no pics of full plant, only pics of leafs lol only small lil buds though.

stinkyattic any feedback?

[stinkyattic]

Really- it looks like not enough light for the amount of water, and the height of the plant. But you have not shown any pics of the WHOLE plants so it's hard to say what you need to do. If you don't have a gallon of fresh light potting soil per foot of main stem, you probably need to re-pot too, but all that damage doesn't add up to any one single problem.
