Please help, having issues in veg.

Illicitmango · Apr 11, 2017

I'm about 5 weeks into veg and they are all starting to look like this. 1 northern lights, 1 is white widow, and 2 of them are clown lady.

The bottom leaves went from a deeper lush green, to a light green, then yellowing. It looks to me like a Nitrogen deficiency, but some of these leaves are getting brownish/dark spots on them that makes me think maybe it's a magnesium deficiency. Thanks in advance.

what are you feeding them and are you using distilled water?

Illicitmango · Apr 11, 2017

Ro water. Floranova grow but only at 1tsp/gal

Locked up maybe

probably need more of that for sure.

are you checking pH?

edit: actually 5mL per gallon should be plenty. i'm thinking more pH being off now

they are hungry, feed them, especially using r/o. If your base doesn't have enough cal/mag. adding some occasionally would be wise

also, are you making sure the FN grow is really mixed well? when i tried it, i had a bunch of crap settle at the bottom of my res due to not being well mixed.

Yeah, I shake the Floranova Grow really good.
Now, I have another question, i read about the Lucas formula, and I have Floranova Bloom as well {the one part system } , I was wondering if I can just use that for the entire grow?

what is your pH too? i'm thinking that it's either off or maybe you have some root issues. how do the roots look?

i used the bloom only aka the Lucas too. no need for the grow. if i remember, lucas is 7ml/gal so your 5 mL should be close enough.

I flushed the soil about a week ago with bottled water. Not ph'd.
But every time I feed or water I ph to 6.5 to 6.7.
maybe the flush, on top of not being ph'd, forced everything out, like I said, I was only giving them 1tsp/gal of the Floranova Grow because they were little.

i'm not a dirt guy, but from what i know, you shouldn't flush.

i think just keep on the 5mL (1 tsp) but use the bloom instead. give them some time and see what happens. they take longer in dirt to respond to changes.

Ok so I fed them, 4ml/gal FloraNova Bloom, Ph was at 6.2
I tested the run off with my ph meter {7.3}
Ph too high causing lockout?

As long as you are PHing the water that goes into your plant, you're fine.

CriticalCheeze · Apr 12, 2017

No need for flushing in soil.

Illicitmango · Apr 12, 2017

I was/am pHing the water every time. The only time I didn't was when I put a bottle of bottled water through them one time.

i think that's what did it. flushed which basically starved them. they should get back on track

From my previous post : The ph of the Ro water after I mixed in the 4mls of FloraNova Bloom was at 5.8, but settled at 6.2. So I watered them with that.
I checked the run off {drainage} water in the catch saucer and it was 7.3.. Does that mean my soils ph is higher than that since it's buffering it and raising the pH...
And in theory, if I continue to feed using FNB at 4ml/gal, ph'd to 6.2-6.7, the soil will adjust to that ph and everything will be back on track? Lol.
BTW, thank you for the help.

don't test run off, it means nothing, your soil ph will change as the soil dries, this is how it takes in the different nutrients. Just keep going in at the right ph and read the plant. It will tell you everything.

Thank you everybody for the help. My girls are greening back up rather nicely and all damaged leaves stopped getting worse. Thank again everybody
