3rd post worsening conditions

[Wulves]

I appreciate all the responses and advice I have received from my previous posts and after carefully follow all the advice we woke up to a horror show after feeding this plant last night.
Profile
Age 10 weeks old
Strawberry Cheese Cake
Auto
Fox Farms Happy Frog
All water PH at 6.3
Feeding
Tiger Bloom 2tsp
Big Bloom 3tsp
Room is ventilated. Avg temps 75°
Humidity avg 45 %
Under individual 50w LED bulbs
Small shower stall grow
No signs of any pests or mold.
I'm stumped .
We are more concerned about the plant suffering and we can't seem to help her then we are about low yields and crappy weed.
I'm asking again ,for help.
Woke up today to this mess.
And yes we did Flush 6.3 ph
Distilled water 3 gallons 6 days ago and fed her last night .
And this is the worse I've seen her.

Hey sorry about the issues.... Have you given them any calcium and/or magnesium supplement? I'm not an expert but I had the same issue (spots,wilting, and yellowing) my first grow and adding cal-mag helped a bit.

Hiya - hard to say but the leaf tips are curling which suggests too much of something
The growing tips are fine, so unlikely a root problem or a micro deficiency
Have you checked the combined NPK of the boosters you are using? And the dosage?
Best guess is K/CaMg lockout caused by excess P and/or N
The brown won't recover, but the clawing leaves should, and the bud will be fine if you can rectify the issue now

right there. pushed too much.
not sure it had the light for it either.

This is what you are feeding if your are doing 2tsp Tiger Bloom and 3tsp Big Bloom, based on Fox Farms Guaranteed Analysis printed on the labels. There should be some sort of Calcium since it lists Calcium Nitrate as an ingredient, but FF never accounts for it.

At least in my world, I like to see:

Total Nitrogen around 150
Phosphorus around 30
Potassium around 200
Magnesium around 30
Calcium around 90

Its most likely a Calcium deficiency and made even worse by entirely too much Phosphorus given the level of other elements.

My tap water is hard it has a lot of calcium/mag in it . To the point it builds up in my vaporizers and plumbing into a white shell.
So we buy our water from stores to water her and make coffee and give the pets.
So I don't think it's a lack of
Cal/ mag
If anything I feel it calcified the roots to the point it can't absorb nutes

Makes sense but my tap water here is hard Artisen well water. Loaded with Cal/Mag to the point it calcified pipes and vaporizers I use to breath. So we stopped using the tap and went to store bought spring water.

Hard to say because FF only gives in percentages .

A three gallon flush did not move out your salts, it just barely got the soil wet. You are still having a salt lockout and there is nothing wrong with the balance of your FF nutes if used according to the feeding chart. Don't let these guys convince you that the problem is the FF nutes.
Flush with 3 times the container size. Use tap water, and don't worry about the pH because there will be no nutes there to adjust for. A 3 gallon container of soil takes 9 gallons of water to flush it. Get on it now. Nothing will change until you do. After you have flushed, do NOT use nutes until it has dried out and needs water again. Let the system reset.

Looks to me like you have a lockout issue, the plants are not able to absorb cal-mag/Phosphorus/Potassium. If it were me, I'd flush them with water, 3x the volume of the pot. After it dries, then go back to feeding as usual. Lockout/salt build-up is very common when using synthetic nutes and FFOF soil. Just a note, spring water can also be loaded with minerals, depending on the source. Did the problem start before or after you switched to spring water? In any case, I think a flush would be beneficial. The damaged leaves won't recover, but they shouldn't get any worse. Be vigilant for bud rot, the damaged leaves are particularly vulnerable to it. No need to PH the flush water. Looks like someone beat me to it while I was typing.

But your correct I do not see Calcium . But now 10 weeks in on an auto and I think it might be to late to correct anything .
And like I said my tap water is deadly full of calcium

the store bought water is probably RO, which has been stripped of cal-mag. you'll need to put some back in if using RO.

Store bought spring water has lots of calcium /magnesium in it ,only distilled water has nothing in it . Try using distilled water on your plants for a flush instead this way you can reduce any thing in that soil , distilled water or r.o. water is the only way to go in my books as you control what goes into the pots and gives a true ppm value as to what is really in your water/feed , the ppm on your spring water bottles will tell you some where on the bottle what's in it (some where between 200-300 ppm already before you even add your nutes plus it will have a ton of salt in it too ).Salt in the spring water plus salt in the nutes doesn't make for happy plants , did you add any perlite to your soil mix , roots need oxygen ,try getting your water down to a ph of 5.9 to 6 but no more than 6 , you cant fix the damage already done but you can still turn these plants around and have a decent harvest ,just not what it could have been , these plants are extremely resilient .

While this sounds good, the only point of a flush is to get rid of the salt, not create laboratory conditions in your soil. The plant wont mind the extra minerals and even chlorine in the water, and everything will be set right again the next time he waters with nutes and pH adjusts that before it hits the soil. Flushing doesn't have to be so complicated as many make it out to be.

distilled can be caustic. most distilled has a bittering agent added as it is not safe for human consumption. the bittering agent can be harmful to plants. RO has little or no mineral content.

if it's comes in the 5 gal jugs it is RO and not spring water. there is a machine in my corner store where you can buy it for a buck or two as well. it's branded as "spring fresh" ... but the machine is an industrial RO dispenser.

Quite true, but it will be marked on the bottle that a bittering agent has been added. That water is made to be put in your car's radiator to reduce deposits in the radiator.

it should be. but is not always. it can make you sick on its own without if consumed as well.

not really. in some it can still be used that way though. there are alternates. that water is made primarily for batteries now, and steam irons. next time note the amount of calcium build up on your iron. it doesn't get it all either.

we used to use a distilled water in radiators, but it's bad for aluminum core rads and modern cooling systems. it eats them internally, and is hard on other coolant components as well. it's clean enough to be caustic. RO is also not really recommended for similar reasons. i have a couple german cars and they are even finicky about the coolant.

most shops use softened tap water. it's now frankly the safest. most cooling systems are now a mix of aluminum, plastics, and silicone based rubber. i boil the tap water first for my personal cars and that's it. aside from making sure i use the right coolant.

i've got pics of coolant system pieces eaten out due to mostly the wrong coolant / water mix.

Interesting. Plants don't have a nervous system nor a brain or brain stem so it is hard for them to feel pain and suffer. They don't even have a stomach or digestive system so they cannot digest or process their own foods.

If you are worrying about the plant suffering then that might be holding the plant back.

But now 10 weeks in on an auto and I think it might be to late to correct anything .

If you want to keep it from suffering then do what can be done to fix the problem. There might be enough time to stop the damage to the leaves so it does not get worse. Plus, adjusting the amount of calcium can produce a better or larger harvest.

You mentioned 10 weeks but is that 10 weeks from planting the seed or 10 weeks from when it started flowering by growing the first pistils? There might be enough time to see improvements.

I'm aware of your biology of the plant. Don't be condescending.
I'm not even going to attempt to explain anything to you.
Go back to your books ,and whatever you do.
There was not one thing you posted that was helpful ,more of a personal attack.
Stop trying to be the smartest person in the room .
And don't respond again to any of my threads .

Slight over-reaction, no?
I guess we'll all just jog on then
Good Luck Pal
