Al B Whats wrong PLease Help

ok Al im running into my first problem i think everything has been good my ph is 5.5 no heat can this be from having my lights to low at some point ive been running 1100ppm changing the res and the leaves look like this these are all the females take a look help me man i got this far

ya know what Al after readin for a while tonight ive been misting my plants a lot and under the lights i think i might have stressed them can this be a good diagnosis

There is a possibility that it is just stress. I was looking at the Grow FAQ and Nutrient Deficentcies, your plants look very similar to a Magnesium deficient plant. i would recomend you check this out.

well im using general hydroponic solutions which one do i add more of for mag?

helllo al b whats glong on man please help

Someone needs their valium this morning

yeah i do i just dont want to mess this up

Hey mosberg i am not a hydro pro by no means.
I have been reading alot about it though.
From what I see in you pics it looks like the plants are over watered and have nute burn.
don't hold me to that I just think you may aught to check this out.

Hope these help.

I think I would remove all nutes. Use fresh water good ph low ppm,
I would also cut back on the watering.
After a few days the plants should look better.
Then I would start with nutes at 1/8th the strengh.

Good luck!

looks like a potassium deficiency to me, but obviously can never be sure, normally during flowering i'd be giving my plants a high doseage of nutes than that and also a slightly higher ph at 5.8 -6.2

wait man im running a low ppm there is no way its nute damage ive been running low nutes my man i think my lights were too close wheres Al B that dude just left me hangin Al B where are you man im getting all these people telling me these problems can u take a look

mosberg, I left you hanging because I was hit by a cop car and was in hospital from 8 April to 20 April.

I explained this to you SEVERAL TIMES in PMs, even had my housemate log on to rollitup while I was in hospital to let ppl know what was going on, yet you come out here in the open thread and tell everyone I've 'left you hanging'?

Would you like a little more experience with REALLY being left to hang?

mos, while I'm really annoyed with you at this instant- your problem looks like high temps.

dude i apologize im sorry to hear that but i didnt get no pms from anyone besides you my man Dude im just buggin out my man i put so much money into this set up and if i fail i will be crushed im sorry to hear you got messed up by a stupid cop my man i hope you feel better bare with my nervousness Hear are a couple new pics Al honesy im sorry if i upset you

I was misting these guys 3 times a day under the lights Al it cant be nuts def right Are you sure its high heat that would make me feel a ton better , I got 6 females out of 9 plants When do you think i should flower?

Some of the plants look fine but the beautiful northern is very crispy i think from the misting my room never gets over 80 during the day so it cant be the heat its gotta be the misting would you think the same?

I mean in pic 3 the plant is fine if it was nut damage wouldnt affect all of them the bottoms of the plants are fine

First- don't mist during lights on. That's part of the problem here. Excessive humidity (or misting) can cause leaf necrosis (dead tissue).

Second- don't mist. There's no need for it in a grow where the temps and humidity are right. Are they? You got a digital thermo/hygro with a peak memory in there yet? The range you need is 24-27C @ 30-50% RH.

Yes All the temps have been fine but i have someone telling me it looks like potassium def What do you think I mean im putting the correct nuts In and im checking it with my meter its been around 1100ppm so how can there be a deficency?

So do you think its def the misting?

Ok here are a ton of pics on what these girls look like im wondering if i should cut the damaged leaves from the misting on the northen Heres a pic of every plant and every plants new growth these guys are pretty big and im pumped to start flowering them Tell me what you think only 3 of them seem to have the heat damage but i think they will be ok i hope

Here are some more of the females Too bad some of them got heat stress

You're right- it is highly unlikely to be a K deficiency if you are using a commercially prepared nute mix.

So do you think its def the misting?

It's the misting, alright- especially a no-no during lights on. Beads of water can focus light on a particular spot. If you put any nutes in the spray you misted them with, you could also have created some localised nute burn.

You can leave the damaged leaves on as they are mostly intact. They won't heal but they will do some work if they are still mostly green and healthy. If they go yellow, pull them off. They're doing nothing but blocking air and light to other leaves when they've died.

if hes using 1100 ppm and they have gotten far enough to show sex in veg, then surely its a def

look at this pic and the margins, the leaves lower down that arent part of the canopy are showing it to, the margins are a lighter yellow which means there lacking the ability to make chloraphyl.

the signs there are consistant with potash def maybe a little n too, he hasnt started flowering yet and i think he should do cus otherwise they going to turn out to be beasts. once he does raise the ppm by quite a bit with flowering nutes is what i would say
