Plant keeps being sick! Help required!

Hey Forum!

I have 5 girls growing here, 4 of them are doing great but one keeps giving me problems..

I'm treating them all the same, giving them the same amount of light ( 400 Watt HPS ) and I'm giving them a little bit of nutrients every 3 to 4 days. ( some flowering nutes, Canna terra flores premium quality with N, P, K, KO, Mg, MgO, S, SO, B, Cu, Fe, Mn, Mo, Zn )

The plant started showing yellow brittle leaves a week or so back and I made a post about it, I stopped giving it nutrients then and flushed the pot with tap water in the bathtub ( I don't own a PH meter and I know this is not the best way, I don't have a choice ).

I then let it dry for 3 days and just started giving it nutrients again today, just a normal dose.

The problem is that these yellow leaves go upwards really really quickly now.. and there is like brown disgusting looking spots on random places on the fan leaves mostly.

I have been looking around the forum to identify my deficiency but i just can't seem to put a finger on it, this is just my second grow and i'm not as well equiped as i want to be yet!

Also I am in the 5th week of flowering now, I hit week 6 upcoming thursday 6-6-2013.

I have some moving air in the growroom too, if that's important information.
My lights are 50/70CM of this plant.
its between 23/27 degrees celcius in the growroom throughout the day.

Well I hope this was enough information for now, I will gladly answer every comment on here to provide you guys with more information!

Here is some pictures to make the problem clear! :D

YOU DO have a choice! PH is VERY IMPORTANT or your grow will ALWAYS do this!
PH test kits are only about $15...to save thousands of $ worth of plants....

http://www.amazon.com/General-Hydroponics-GH1514-Control-Kit/dp/B000BNKWZY

if you really 'dont have a choice' and cant afford the $15 to test your Ph...then do yourself a favor and quit growing...
I tried for years without it....what a waste...
Controlling your Ph will solve this problem....forever....

Hey man, I checked amazon but I can't buy anything on that website, we don't use credit cards here in The Netherlands when we're 22 like me.

I checked for some PH meters in growshops nearby, they all costed 100 euro's or more :/ this kinda kept me from buying one!

I understand that I should purchase a PH kit, but for the time being.. what's your view on the problem ?
What do you think is wrong with the plant ?
If it's really a PH problem all my plants would show these symptoms and they don't, they actually look really healthy with beautiful big buds full of resin.
They all get the same water since the beginning.

It's really hard to say without knowing the Ph.

Ph is VERY key... you would be doing yourself a favor to hunt down the cheap kit...
your Ph could be low or it could be high... and both would require different treatments...

I'm guessing a flush is needed...but it cannot be said for certain, without the proper test...
Ph is funny...not all your plants would react the exact same...
the same feed could throw one plant waaay down in Ph and the one next to it could very well stay the same...
your healthy looking plants may be on their way to looking like the bad one...
just slower in progression...not something I would risk...

remember too.... sometimes in late flower leaves yellow as nitrogen runs from the fan leaves...
it's not necessarily bad...


if I had to blindly guess...I would say you are too N rich and need to flush....but that is just a guess without Ph and PPM readings...

Before even reading this the first thing that popped into my head was a PH problem. If you have constant problems, one after another. You're either extremely incompetent (unlikely), or your have a PH issue (most likely). By a meter dood, it's like 45

I know it doesnt make any sense to you now...
it didnt to me either...

I put off buying a Ph test kit for 2 years and had plants do all sorts of crazy things...
and all plants responded differently...even though I gave them the same feed with bought distilled spring water.
but all were either weak as shit....or had severe problems way before harvest and had to chop early.
because I ignored everyone's suggestion to buy a cheap Ph kit.
I have had ZERO problems since I spent the whopping $15 to buy one
and I almost want to cry thinking about the 4-6 grow cycles I ruined because of my lack of listening to the pros.


PH is everything...
you can stop cancer from growing if you have your body Ph right.
a Ph of 6.3-6.8 is needed for the cannabis plant to absorb all the nutrients it needs.
If you dont test your Ph...you are flying blind and will ALWAYS have problems.

I'm assuming that in the Netherlands you can find a hydroponics store?
If not...try the gardening section of a hardware store or a pet store...
A simple Ph test kit with some Ph UP and Ph Down that is suitable for plants is all you need....

Wal-Mart sells the cheap liquid style PH testers in the pool section. Consequently, they also sell PH up and PH down in the same section- Awfully convenient:) Do they have Wal-Mart in the Netherlands? If not I would search for one anywhere that sells pool-maintenance items.

if your flowering 5 medium sized plants under 1 400w hps, the bottom leaves are not going to get very good light and the plant will cannibalize them. another possibility is that the bloom nute you are using does not have enough n so the plant is taking what it needs from the older leaves. there might be a ph issue but it doesnt look like it to me. the soil test kits they sell at garden/hardware shops should work fine. hth

My ph meter recently broke and whilst waiting for a new one I used the drops. But you tell they weren't too happy about the fluctuations.

Alright, you convinced me <3

I will go ahead and order a PH kit online today, I found a good one!

Just one questions though, will my plants show improvement quickly and will it matter a lot in bud weight for the next two weeks to go ?

And I will just have to measure the PH of my water that I give them, correct ? And get it around 6.5PH

I will chop them down in around 2 weeks I suppose, trichomes look very milky already in week 6. I assume they will be 25% amber in 2 weeks.
