problems making me go insane

hay guys, so i am using 400w hps and the big girls are about 5weeks old,there are 3 fans blow7fresh air around and the light is about 17 inches away from top of the plants,the white /blue spots is stuff called "virikop"(treatment of broad spectrum fungicide and bactericide)that nursery suggested, and feeding once a week with "wonder surranure plus[3:2:1] ,the ph is constant at 6.8, there are a couple of very dark leaves,yellow and dark spots and edges curling in,how do i fix this,i dont want them to die....help save a lifekiss-ass

white powder mould...no?

Is that a Towel under your Ladies...? Is it Damp? y'know from Run-off from waterings...

What kinda Temps/Humidity you got?

Hope you sort.

Peace

EDIT: 5 Weeks in Veg, what size are ya Pots...?

They Don't look too Bad, you can probably save IMHO quit giving that stuff from nursery and the other stuff, just water a couple of times over a couple weeks...Why does everyone concern them selves SOOoo much with Ph...never had a problem with this and I don't even check anymore: Mind I am a Soil/Compost/Perlite Grower...

it says 6" pot,its not mold,the dark spots worry me,the towel waz just temporarily there

all of the plants
have these spots

will it get better? the seeds came a long way so I really wanto keep it going

Looks like a phosphorous deficiency to me.

Get rid of towel use plastic tray. I'm seeing on here so many issues with soil. Here's 4 week veg ak-47 only use 1/4 of nutrients asked for. Simple ebb n flow I'm a newbie btw

how do I fix that?should I stop feeding nutes

should I try different soil,transplant? what's wrong with the soil

Why are you hammering those poor plants with that Virikop?

Do you have equipment to check pH an ec of soil?

id actually research a cheap hydro method 25 dollars tops can run 4 sites. this is about 12 dollars a bucket

you need 4 5 gal buckets 4 airstones drill airline hose and airstone net pot and water and presto up and running just enough water to cover the roots is all you need change water once a week i use a veg n bloom about 2 tsp and its off we go

ph tester any pool shop walmart if you need ph down lil lemon juice works. but what do i know I'm new...

I don't know need you to test it. But for 1 I see many sticks n chunks of bark. I'm assuming peat based. Your ec is prolly high, or your pH is prolly low and your plans just can't get what they want when they want it.

Liquid limestone to rase ph. PH feeds to 6.8 if soil is in a pH range below 6.0. If your ec is over 500 in your soil put 3 gals of untreated unph'ed water thru your pots for every gal of soil. Then wait for soil to dry on top a Lil bit before feeding again. And start back up feeding at like half strength

2oz of 7.0 water and 2oz of soil out the pot, mix together and check with your meters. It will give u a pretty close estimate on your soil conditions

pH 6.8, i just applied it 10 min before photos, took it off after a few coments,

Hiya a45man, hope you manage to save em..

Question: Why did you start giving the Ladies "virikop"(treatment of broad spectrum fungicide and bactericide)

And I can't comment on ~ "wonder surranure plus[3:2:1]

I've Never used it.Is that Fan Blowing straight up @ 400w Hps? then where does you built up heat go?(do you leave door open during Lights On) also what about your placement of Other Fans? where are they...

From the Look of Pics..I would say you been training the Ladies(The white string)...

What kinda Soil/Compost did you use...Most feed Plants for first 4-6 weeks??

My thoughts(could be wrong)

The Pots are too small now for Ladies(Might be a little pot-bound) 6" is not a lot of space/room and with smaller pots means more waterings...

Do you have Perlite in your mix?? IF not buy some and while you at it get some soil/compost(seedling Compost) sit in a BIG pot and pour loads of water through the Compost a few times then let go nearly dry(Put in cupboard nr Fans n Heat) when dry but still a little moist..then add the Perlite and mix in well(you want IDK maybe 60% Perlite + 40% Compost/Soil..next get some Pots that are at least 15-20 ltrs 3-4 Gal at least, then you won't have to pot-on again..though that depends on Veg time...Bigger Pots can help with a Longer Veg..from what I've read...Its so many Gal per month??? you can Google this.

So fill up ya BIG *new POTS with the Mix you made Seedling Compost + Perlite(The Reason I suggest Seedling Compost and Flushing through lots of water is

(a) Seedling Compost is more delicate and contains Less ADDED feed/Nutes
(b) And by Flushing(this will remove a lot of this ADDED Feed,though not all.

Then be patient let they Ladies enjoy new home, don't water unless they really need for maybe 5days at least if unsure put your Little finger in soil(1-1.5") at edge of Pot, If Compost/Perlite bits stick to your finger...leave her..wait another day...

After a week or so in *new BIG pots they should have started to Perk up...



Do you check Humidity and Temps for Lights on and Lights off?? or are ladies under light 24/7?? I do 18/6 gives em down time(Rest) and saves on Leccy.

Peace

thanks S I'm gna try that,the lights are on 18/6,i gave 650 persent nutrients that was suggested,in s.a they don't give descriptions of what's in the soil,i know it sucks,but it jyst said proffesional pitting mix,when should I add nutes after replanting them in there new home
