Think you are feeding her too heavily. I would flush her completely and start over with nutes after you see nice growth.

What is the age of your plants? 4 weeks into flowering.
How long have they been in the soil mixture they are in now? 7 weeks
Were they in the same mixture when they were seedlings/smaller plant? If not, what mixture were they in before? Same mixture, smaller pot.
How Tall are the plants? Tying them down with strings. Height is approx a foot
What PHASE (seedling, vegetative or flower) are the plants in? Flowering
What Technique are you using? (SOG, SCROG etc). Tying them to the pot in circles.
What size pots are you using? (Include how many subjects to pot). 11L
What substrate/medium are you using? What brand of soil mixture are you using?(percentage of perlite, vermiculite...etc?)
What brand Nutrient's are you using? Pure Blend pro. Organic. nitrogen 2.5%, 2% phosphte, 5% potash 1% Calcium, .5% magnesium
How much of each nutrient are you using with how much water? *Knowing the brand is very helpful*. Recently been using about 5ml per L of said blend and watering about 2.5L of mix
How often are you feeding? Around every 2 days
If flowering, when did you switch over to using Bloom nutrients? 4 weeks ago.
What order are you mixing your nutrients? (example: veg nutes 1st, bloom 2nd ect). Just using bloom nutrients
What is the TDS/EC/PPM of your nutrients used? I don't know.
What is the pH of the "RUN-OFF"? I don't know.
How often are you testing pH/ppm/EC/TDS? Every watering.
What method of pH test was administered? Using Strips? pH pen? Testing the water in a test tube with ph drops. Measures in around 6.5
How often are you watering? every two days or so.
When was your last feeding and how often are you feeding? 12 hours ago. Every two days or so.
What size bulb are you using? 5 x 42watt CFL
How old is your bulbs? 4 weeks
What is the distance to the canopy? Assuming this means distance of lights from
What is your RH Factor? (Relative Humidity) Was at 30 and i just bought a humidifier yesterday. Currently sitting at 45.
What is the canopy temperature? not sure what is meant by canopy.
What is the Day/Night Temp? (Include fluctuation range). Day around 25-29 and over 30 close to the lights.
What is the current Air Flow? (cfm etc.) Not sure. Likely above 600
Tell us about your ventilation, intake exhaust and when its running and not running ? Always running two computer fans. Day time additional oscillating fan is running.
Is the fan blowing directly at plants? yes
Is the grow substrate constantly wet or moist? What is grow substrate?
Is your water HARD or SOFT? Not sure
What water are you using? Reverse Osmosis (RO)? Tap? Bottled? Well water? Distilled? Mineral Water? Tap water city.
If using tap water, what is the ppm/EC/TDS of the water right out of the tap?(Only if you have a tds pen). Don't know.
If using RO,Distilled,mineral water, what is the ppm/EC/TDS without any additives?(Only if you have a tds pen). Don't know.
Are you using water from a water softener? No
Has plant been recently pruned, cloned or pinched? Yes. Cut off dead and dying leaves 4 days ago.
Have any pest chemicals been used? If so what and when? No
Are plant's infected with pest's? Not sure. I hope not.

It looks to be potassium deficiency due to Ph problems most likley, its very hard(Not impossible) to over fertilize in organic because the elements stay within the soil and the plant only eats what it wants too. But most of the time I ran into Ph problems from the nutrient solution itself and that will cause your soils Ph to drop most likley.

They may need more K but the main problem is Phosphorus. The way the leaves are going straight to crispyness without much if any yellowing is indicitive if P def. Try to give them a ratio close to 1-3-2 until the problem is fixed. This will repair the P def, provide more K in case it's a factor while still supplying some N as well.

I just finished flushing with tap water. Let's hope she looks a little better in the AM. When do you guys I suggest feeding her again. Should I wait until the flush completely dries up or get in there first thing in the morning?

You'll have to wait and see what the flushing accomplished. If they get worse in the next couple days then you need to fertilize them asap, but you'd want to wait until the soil dries a little. While you're waiting for the soil to dry out enough, you can still give them weak nutes in foliar feed form.

Thanks Mother's Finest.

So, here is an update after the flush. Leaves are turning green again. Still a lot of problems though. Plant is weak, drooping, and over all looking like it needs some help. Leaves are feeling more soft and moist again (opposed to hard and dry). I'm not noticing any new growth.

The soil has dried up. Considering she's organic, does anyone think I should feed her with half nutrients tomorrow, or simply with a ph6 watering and then feed her on Sunday. My last feeding was last Sunday (tonight is Thursday).

Hard to say if I've made progress.

here is a shot. I'll try and get a couple more tomrorrw

Here, this should help. First, this is a plant that is P deficient during flowering:



Here are plants that are K deficient during flowering:

You may notice that your plants are showing a combination of both problems.

problem is u need to spend some $ and buy some real nutes (foxfarm).........btw NEVER EVER EVER EVER EVER use tap water...........

You are having other issues sorry to hear about that and using tap after is just fine as long as you let it sit outside for a couple days to remove contaminates & I use it every day

So if you're saying this is a bad thing


I don't want to be right, I also use Roots soil and add just water to my plants since everything the plant needs is found in the soil

Good luck

I thought I'd send an update. It was a rough 2-3+ weeks. Things are looking up, however! I'm pretty sure the issue was a combination of nute burn, flushing with high ph, and ultimately nutrient loss. She lost a lot of leaves and I can only assume bud development slowed quite a bit. However, after all the drooping stems, and dead leaves she has regained her strength and i'm even starting to notice crystals and signs of advanced bud development. She is not half as sexy as she was but all of the tops pushed through the war. Here's to the last three weeks or productive bud development.
