i agree,,,, and your temps. fine.... pick your pots up after watering,,get to ''know the feel'' of a fully watered pot,,,

let them go for 3 or 4 days and pick your pots up again,,,, they will feel lighter,,,, use this technique for when to water and not to water,,,,,

and use no nutes for a while,,,, if your soil has ''time released ferts,'' then you may have killed these plants.... allways use a neutral soil, no time released nutes in your pot plants soil,,,,,

if thats miracle grow,,,, get ready for a pot plant funeral,,,, good luck!!

I'm amateur, but not that much.....

The soil is Organic, no nutes.

I fed once about 3 days ago

I think it's over watering, ive already cut back and they seem to be doing better.

They are about in day 15....

im still amateur too wit same problem,but those temps ..wow..wish i had 'em, jus easy up on water,wish u good luck man

[azybaby]

btw.... how big is grow space ,is reflector air cooled,and whats the distanse from tops ?

[Homergrower]

I think it may be a humidity problem.......

It's a small space , only L=80cm x W=80cm x H=200cm

I've got a 150mm Inline fan sucking through a carbon filter.
With 4 passive intakes,

And one Active Computer fan intake at the bottom.
Check out the indoor chamber link at the bottom for better pics of the space.

The problem is the humidity is about 35%..... I've added 2x cups of water.

I think there is too much air moving through the cabinet, but i need that much air to keep the temp down.....

CAN SOMEONE HELP PLEASE.... !

hey man, 35% humidity is fine imo.. my latest grow stayed at like 20% during veg with no problems at all.

how far is that light from the tops, They look pretty young to be under an HPS that's close to the plants.

what are the temps between the top of the plant and the light? imho you can never have too much air moving through the cab.

whats your problem man? ..........3 of us agree to what your problem is......


No, too much air moving through your cabinet wont cause yellowing, droopy leaves beginning to show defencies

my problem is that, i don't think it's just over watering, as i stopped watering and the plants have dried out, the problem is getting worse, The ends of the yellowing leaves are all crispy and just broke away in my hand.

I'm watering using rain water
And it's an organic soil.

I was under the impression it may be too dry in there.
Temps are around 83 highest, to about 76 minimum.
Seems to be alot of purple colour in the stems.......

Light was at 50cm, now been moved to about 60cm from canopy

I'm at a bit of a loss ?

[Ganja Guerrilla]

just letting the soil dry out doesnt fix the issues immediately, the roots need to recover from the shock they are in and possibly somewhat rotted? and the purple you see is part of the defencies I was talking about.

whats the brand name of the soil your using ?

thanks for the quick reply.

I honestly don't remember the name of the brand, but it's organic, no nutes. from the Nursery..... big yellow bag if i remember.

I was getting worried as i hadn't watered for a while and the soil is very dry.
So you think it's just over watering.

Can i add anything to the soil or water to bounce them back...
or just lay off the watering.....

[Ganja Guerrilla]

they are a little to young for ferts, but in a couple days you can give them 2 drops of SUPERthrive in 2 cups of water and split that between the 4 plants.


start feeding @ 1/4 strength ferts in 2 weeks


I recommend Miracle-Gro® Water Soluble All Purpose Plant Food (they make several fertilizers be sure its this one)
http://www.miraclegro.com/index.cfm/...c0236933b0a7a4
Fertilizer Analysis: 24-8-16 with micronutrients
2 level "Teaspoons" per gallon of water, (reduce this by 50% first time application) feed every other watering till flowering

Budding ferts I recommend Fertilome, Root Stimulator and plant starter....
the NPK is perfect: 4-10-6
2 teaspoons per gallon of water every other watering........ use this as your water ...discontinue use 3 weeks prior to harvest...flush last 2 weeks...thats it no water .....
