What am I doing wrong with my Supersonic Cristal Storm Automatics?

[Tenakey]

Hey guys!

This is my first try, Im borrowing a DR60 tent with 200w cfl light.
I got 3x Supersonic Cristal Storm Automatic in 7l pots.
I got fan blowing on the plants, one fan blowing out air at the top, and passive air coming in at the bottom thru a window in the tent.

I got some medium with around 6-6.5ph, and some vemiculite and leca with that.
Around 29c daytime, and 25c at night.

What could be the problem with these spots on the leafes?
The baby on the picute is 15 days old, the other 2 are just 7 days and are not on any pictures, but are showing the same issues.

I have been reading lots of people give their plants a lil bit of urin mixed with loads of water, in the vegg phase, so I did that aswell, only twice tho and 1dl urin with 20dl water. Other than that, no nutisions what so ever.

Is it wrong PH? Or am I watering it wrong? I did water it a few times from water straight from the tap.

I dont have anything to messure PH or humidity with, and not able to get one for weeks.

Anyone have any ideas?

looks like ph might be off a bit... showing some phosporus deficiencies.



I'd get a soil and water ph meter ASAP... its really key.

Might switch to catching rain water and bubbling it for 24 hours... that tends to stabilize ph pretty well... see FD's guide in my signature.

cheers mate

The rust spots make me think cal def. JM is right it could be PH causing it. If your PH is 6.4, it should be ok.

In which case she is just hungry for some Cal.

I wouldn't use urine very often you'd be better off making a compost tea with some manure or guano.

bailerbuds! on the money I'd say!
:thumbs:

maybe a lil mag def too starting

Cheers for the replys guys, I stopped with the urine, I guess I will have to invest in one of those soil and water ph meter.
I cant get one for another 3 weeks tho, any tips what i could do meanwhile to not make it worse?
That was probably a stupid question tho, pretty impossible to tell from a picture i guess
This growing thing was harder than I thought tho. This "Def" word you use, as in calsium def, does that def mean it got too much of it or too little? My english dosnt strech that far

Thanks again for the help

This is how she look today (day 18), there is a yellow leaf at the bottom, and the "body" of the plant at the bottom just above the soil looks sick, some dots on it? or this is normal?

 

[agito]

pic 2 leader leafs always yellow and the bottom leafs seem like nutrient splash when feeding

 

[Tenakey]

Thank you for that info sir.

Im assumin its cal def after readin some more on this forum, since the lower leafs are yellow and might be dead already.

May I ask what I should do, could I remove these bottom yellow dead lookin leafs, or would that hurt the plant? Or will they repair themselfs?

Ill add a photo right now,

Thanks for all the help so far guys!

No need to do anything with those leaves. They'll fall off on their own if the plant wants to be rid of them.
