Take a look at the Pic... leave your ideas inside

this is my first grow... Started with about sixty plants.
Completely fucked up some of them, about killed a few more. Started the GROW at 9:00 December 31 (Thats right, I couldn't think of a better way to bring in the new year!)
Getting close harvest time and i'm pretty late into flower. (I vegged for 5 weeks).
So now I got leaves drying up like the dickens... I can't figure the shit out and need help.
I'll give you the setup:
11x11 room
3x1000 HPS
8" can fan exaust with Phat filter
4" inch intake at the moment (10" will be here friday)
Temp (Day)consistent between 78 and 82 degrees
Humidity at 32 in the day 52 at night.
Soil is flower power
Soil is Ocean forest
Nutes are Fox Farm (Big Bloom, Big Grow, Tiger Bloom)
Water is PH'd with Hanna meter.
Water is oxygenated with pump.
Also use cal/mag each watering.
Here is a pic of leave i pulled tonight.

I need help...

that's normal man.in the end of it's life, the cannabis plant will get all of it's power to create the buds.peace!!! cheetah

have you been flushing?

I'm not exactly sure because you have only posted pics of leafs but i think your plants should turn out fine usally when it gets late in the flowering stage your plants try and use as much sugars and energy as it possibly can to produce nice buds, just keep going with it and dont stop you will figure it out.
Strictly'dope

its fairly normal ..especially with fox farms...pretty hot nutes...

If you mean flushing, by using nutes every other watering then yes I flush. But other than that, I have not flushed plants. I thought some of the leaves would begin to turn as I got close to the end of flowering. But I saw some pics of Trentons plants ( I think) in the tutorial of fdd... and just about every leaf was still green... so I was like... err what hell?

Flushing means to put alot of water threw the soil until what runs out the drain holes is clear. You should do this about every month to get rid of the salts that the nutes leave behind. It is really good for the plants.

popped the light on for a sec (incandescent). here's a pic.

Looks worse than I thought.

I know what flushing means... but i wasn't sure in what context he meant. But thanks for the info

It looks to me like your plants are burning,i'd flush the hell out of them & cut way back on the nutes,looks to early in flowering for that kind of leaf damage, plus most of the leaf damage looks localized to the leaf tips,not the way leaves normally dispose of their selves durring flowering.

nute burn big time

yeah I was thinking the same thing about the type of leaf damage. thanks

How much water should I flush through each plant... and is it ok if I un PH'd tap water?

Im not positive either way on the non ph'ed tap water for flushing but as easy as it is to correct the ph levels i always correct my water before a flush,its just too simple a task to overlook or skip, i do use tap water that has been allowed 48 hours of evaporation & oxygenated for watering & flushing.

From everything ive been told & read were supposed to use 3 times the volume of the pot to flush with,for example a 3 gallon pot would require a 9 gallon flush,this is massively excessive,i use 1 gallon to flush my 3 gallon pots with & around one half gallon for my 1 gallon pots & its worked perfectly every time.

I am not the most experienced here but how far are your lights from the plants because i swear it looks like the tips are burned from heat and not so much from nute burn...

If you look at the burn pattern on the plants you'll see that light/heat burn is unlikely,the leaf damage is equally dispersed throught the canopy & well below the canopy,in some cases the damage is more severe well below the canopy.

Flushing... there is no way I can ph 60 gallons of water ( don't have that amount ready)... nor do I have 2 days to wait for proper water while the plants continue to burn. So it comes down to waiting or stopping the burn flushing it with unprepped water. I would say stopping the burn is more important... ideas?

it very well could be..i cant blow the picture up to see below the canopy.....in the info for the grow it didn't give a distance of light to plant so i just wanted to make sure it wasn't overlooked...................if your light is a good distance from the plants then just ignore my post but if they are close i would back them off a little and see if your problems correct

I agree with not waiting but the ph deal im worried about,you dont have to ph every last gallon of water to flush,after you flush everything with room temp tap water then you can take a 5 gallon bucket,fill it then ph the water then give your flushed plants a quick rinse.

I cant see very well from the pics but the damage doesn't look like nute burn to me. It seems to occur sparaticaly on all different parts of the plants. The pic of the top-middle leaf on the first pic looks exactly like the textbook pic for severe phosphorus deficiency from the medical marijuana growers bible. I have burned my plants using the foxfarms trio and it looks different from what I see in your plants. Either way I def agree with flushing your plants. If it doesn't get better then I would suggest adding a little more Tiger Bloom then you normally do. Thats just my 2 cents.
