What do these leaves say to you?

Hi
I am growing a Nirvana White Widow in Happy Frog soil. She's in week 4 of flower, and has been dropping leaves lately ... not only from the bottom but the mid-levels as well. All the fans are starting to yellow. I have been feeding her using GH Flora nutes ... the Basic Drain-to-Waste program. In late veg, this meant 7.5 ml Grow, 5 ml Micro and 2.5 ml Flower.Now I've been using transitionmix ... 5 ml each into 4 liters RO water.
I thought N or Mg ... until i began noticing these brown necrotic spots. the leaves are still supple ... no overfert "crunch".
All the usual Visual Guides sugest either K or Ca deficiency ... but GH Flora has good amounts of these ions.
So, anyone experience this before? What caused it for you? cn

Feed me. That's what I see. Looks like it needs more of everything.

How's the ph?

I've been watering for over a month now with a TDS of 750 to 1200 ppm. I don't think she could stand much more.
As for the pH ... about 6 going in. I don't have the equipment to measure soil pH. I've sort of run on the assumption that "good soil brand = no pH worries". cn

are you mixing yur nutes for RO water or reg water? @1200 ppm they should be green ... you might have a lockout


you could foliar feed to get it back some nutes but you gotta figure out yur prob

That's usually the case but buildup can happen and screw things up.

Like Dizzle Frost said, it might be lockout, probably wouldn't hurt to flush the soil.

thats what id do to
i keep a jug of clearex around for jus incase times....its saved me a couple times from salt buildup and lockout

I was wondering if I had lockout ... so a coupla weeks ago I flushed my soil.
It didn'thurt ... but it didn't help either.

I'm mixing my nutes for (and with) RO water. cn

So what is causing those brown lesions? cn

I'mo it's Phosphorus. Use Kool Bloom or bone meal and maybe some nute with a lil' N in it for this watering. I actually have this issue happening in some of my plants and just upped the bloom nutes (Using Botanicare PBP though) and folliar fed the affected leaves with a very diluted grow solution. Yellowing stopped. I could also throw Root bound to the mix.. how big are your pots?

Phosphorus makes sense! I'm in 7-gallon cloth pots. I'll switch to an "aggressive flower" ratio on my GH Flora ... and see how it goes!
I'm hesitant about foliar-feeding ionics. I've caused more problems than I've solved when the droplets dried. cn

looks like simple over watering to me
