What's wrong with my girls?

I'm currently growing 3 different strains of clones (organic). One of the strains' leafs began turning brown 3 weeks ago. I thought it'd be over nutrition so I watered with water only for two weeks but the problem still exist. Im using roots organic and I've fed them aerated tea (bat guano, vermicompost, blood meal, molasses) in the past but I'm not sure if this is due to overfeeding. Can someone tell me what's wrong with my ladies and what I need to do. Pix are included. Thanks in advance.

They are still hungry. Feed them something.

Are you sure? Do you think it's because they lack nutrient? I think I overfed and their leaves were curling.

If you picked those leaves off of the bottom of the plant, they are most likely N hungry.

They are from the top not bottom. Could this be plant disease? Could this be the water filter I'm using to get rid chlorine?

P&K are too high......
too late when it's high up on the plant..
They'll finish but NO "bloom food"!!! Go back to a veg food and run them out....

Next time NO high P bloom foods till week 3 after the flip to 12/12..NO big P booster supplements at all!

What soil may I ask please?

Doc

Hi Doc sorry about the late reply but the soil I'm using is 707 roots organic

No, don't go back to 'veg food', that's way higher in nitrogen than a bloom fertilizer, which will inhibit bud growth. If your leafs are ALL like that, it's only a matter of time till she dies. The plant's fan leaves are necrotic(they're dying), sorry to say. So depending on how wide spread it is, if you haven't passed the tipping point, you could just make sure you're testing ph levels of the water you use, and making adjustments(before you water), you'd be surprised how far that can carry a plant's health.

give phd water w a sm. bit of superthrive ..3 drops per gal along w 1tsp. molasses until finished..which isnt far off from the looks of things...make sure she drys pretty well between watering

No it won't! Not in the NPK numbers sold today......You would be surprised to learn that many formulations of bottled nutes are actually low on N for bloom! Canna needs more N in bloom then many think! This is the case when high P&K bloom foods are started to early......The blast of P&K actually begin to block the uptake of N! When this happens, you need to up the N and back off on the P&K....

Case in point on the N.....any 3-1-2 nute can be run straight through start to finish! Using a 3-1-2 nutrient is a good place to start with giving the plant a "bump" of a P&K supplement at week 5 or 6 and seeing if that works to increase yields......It's called learning and many simply and blindly flip to bloom nutes too early and get the problem the OP has.....It's the most common problem I see around here...

pHing in going in synthetic use IS a good idea and should be done, if you don't keep the micro herd working for you!
