Don't know what the problem is here.

[SmokeyTheBear]

I have two plants that each have two big fans leaves at the top of the plant that look like this. Anybody know what the problem is here?

The rest of these plants and all the others look great.

Looks like a ph problem and now you have a lock out. Probably locking out calcium. Those rust marks usually indicate this.

What is your medium? What's your water source and are you feeding with nutes? A re pot can help when you have an issue with ph.

Kind of looks like rust...humidity to high but that usually shows up on all the plants in your...some of the spots almost look like water burn....droplets on your leaf from watering...but the yellowing might be and nitro or Mg issue....I'm not an expert by any means but I've plants that showed like before in my buckets...being that I use bio buckets...not sure if that translates for hydro growers....hope this helps a bit.

I see alittle "clawing" to start. Your fan leaves look dark to me, I would water down your feeds a bit more. Right now take a week of watering regular PH'ed water you can pull these leaves off and keep an eye on the other leaves for the next week. Then continue your feeding schedule. Hope this helps. _ do you have any full plant shots so I can get a better idea on what your working with.

Ever since I started using EWC tea and feeding with guano I have stopped having these kinds of issues. No leaf spots, clawing leave, deformed shit, it all went away just lush green leaves and explosive growth. I don't have to monitor my water pH, just make sure it's bubbled for 24 hours and good to go. Tea and guano is the shiz doubt I will ever go back to bottled nutes and their problems again.

My first thought was "cal/mg issue".

more infos on grow and pics from whole plants are usefull

 

[hereigrow]

A little more info on your setup would help. What is your nute regime? Tap water or ro? Have you noticed any pests near your substrate?PH of run off and nute solution?TDS? You can always remove effected leaves and flush the medium....have you added anything to your normal method?
I know i got lots of questions. Hope i can help

I usually keep about 20 gallons in milk jugs of water laying around to make sure that any chloride in water is broken down. I add nutes when I feed. I feed every Monday. Never had a rusty looking problem before. Although, lately, I've been busy with work outsides chores etc.... so I've just been running over to the sink and filling the jugs when needed and watering. When I feed the plants I give them 1 tablespoon of earth juice growth catalyst, 1 teaspoon of cal-mag, 1 teaspoon of molasses, and every other week i switch flowering nutes. one week i'll give pk 13/14/ the other week i will use advanced big bud. I water twice a week. One with all the nutes and the other with just water cal-mag and growth catalyst. They are flowering currently.

Well from my experience i had rust spots on a recent crop and i thought it was cal/mag , but I was using tap water and normal thought is tap has sufficient cal blah blah...that wasn't the problem. It was the molassesactually I added it to my nute program and i got rust spots everywhere growth slowed big time. It was regular grocery store molasses , it made my nute rez have this weird bubbly emulsion on top after a day. I did some research and looked at the label on the back of the bottle,the molasses I was using was loaded with sodium locking out calcium and potasium. It cleared up when I stopped feeding with it. I like sugar daddy from tecnaflora for a substitute..I know people like to use molasses but black strap I think its called...

Idk maybe you have used it for years , but it was a problem for me.

Here's the pics of my molasses caused rust spots.

Thats my first thought as well.
Calcium.

My first thought was "cal/mg issue".

I think this is an issue with Calmag! that somehow the balance between Mg and Ca is out of whack.

if you google 'Mulders Chart' you will see how too much Mg will lock out Ca ... and vice versa.

this out of balance could be occurring because of a build up of Mg in yr soil (if you are a soil grower).

OR yr pH is out resulting in excess Mg uptake which will reduce Ca uptake.

plants need Ca at flowering time (usually in combination with N) if this were my problem in soil I 'd sprinkle some calcium carbonate or lime ... like sugar on a donut, no more ... on top of the soil and water in well.

also, because the plant is in flower the fan leaves will be losing their vigour. they're going to die off soon and this is why the problem shows worst there.

but first thing test yr pH if yr able to ... THEN set about adding Ca if you need to ...

cheers!

cal mag

if it were lockout due to ph it would be global unless that particular container has some specific spots where the soil is biased (improperly cooked organic amended soil for example)

I hate to give away my secrets but there is a simple protocol to follow when spot treating a plant that may have deficiency or lockout and your unsure of which it is

if you are unsure of lockout or deficiency you can always flush and foliar

Flush your medium and treat the plant with a foliar application as if it is a deficiency because in essence it is regardless and if your unsure if it is burn it is better to flush and re-feed than to let roots burn longer

baby the root system and feed it through its leaves to bypass the root system in the interim

plants react fast to folair feeding so it will address the nutritional needs quickly regardless of whether it is a deficiency or root dysfunction so your helping the plant recover and hedging the bet on regardless of over feeding or deficiency (that how we fuck up in the over or under)

Foliar at 1/6th strength

Not really a secret bro. That's 101

common sense yes

commonly posted no

if it was so 101 more people would do it instead of asking and letting their plants continue to decline

I just flushed everything with water and clearex. I'm going to wait a day and then water the plants again with the growth catalyst, tigerbloom and bigbloom. These will be the only nutes for the rest of the flowering period. Should I add any lime to the gallon jugs tomorrow?

 

[hereigrow]

You put lime in your water? Ive never heard of this. R u talking dolomite? Idk man I would just let them go thru the normal wet dry cycle before you water again. When you flush your supposed to use plain water and the last part of the flush a light nutrient solution. Idk what kind of soil your using ,ffof?

Clearex gets everything out of the soil. I use promix. I will water them again tomorrow when they're not sopping wet. Seems pointless to me to water them at the end of the flush with nutrients. It will just run right out the bottom.
