Does this plant need more Calcium?

Using FFOF and Feeding this.....



I have no clue what the soil pH is and no way of testing it.

it does look like early stages of calcium deficiency. if it gets worse cal/mag will do it. there are home remedies also. GL

I agree with Po... also appears to be the beginnings of magnesium def as well. Certainly cal/mag is something everyone should have.

It isn't bad yet, so mix a 1/2 dose in with every other watering for two sessions, then hold off and see if things appear to improve. Then, feed a 1/4 amount in every 8th feeding or so. One 1/4 dose in a mist bottle immediately as foliage spray may quell it until the plants start absorbing what you put into your medium.

If it gets worse, post back.

thanks for the posts, anything else it could be besides Ca?

It 'looks' to be a calcium and magnesium deficiency... the early stages of both. What's your medium, and what are you pHing to? They look good other than just the beginnings of the traditional cal/mag def.

...and for the love of all things good, only change one thing at a time. calmag, that's all. Don't adjust anything else while you try to sort this issue, or you'll never know what fixed it (or worse, what killed it). Again, plants look dope as they are. I can tell they are properly watered and cared for. Be easy

I always recommend General Organics cal-mag+ use it at 5ml a gallon or roughly 10 large drops.

CalMag is like 5% Ca and 1-2%Mg?

Pretty sure its a calcium deficiency am I right?

^^^ up the Cal/mag for sure ^^^

mixed 2 table spoons of dolomite lime in with top layer of soil, seems to be getting worst

Sounds like a lockout,

your probably more experienced than i am, so im not sure how much help i can be as i mainly just spend my days reading on here waiting for mine to be done. but this might help i have it on my wall ahaha, if not hey i tried right? GL

Lockout,

^^^ aye i just came to this page didnt see the first one and was saying in my head,looks like start of mg def, then that last of 3 pics looks like overfert,,claw,burnt tips,etc.

koo koo, stopped the feeding the other day and actually had some drain off using just water, so maybe it will get better

also did some research on how to make the dolomite lime water soluble quick and easy, vinegar + dolomite lime, comes out smelling exactly like GO CaMg+, thinking about fermenting some molasses for a day to add to it

So your 1st ingredient on that tiger is calcium nitrate

yea I think it might be Ca locking out Mg
It happened to me; I just gave 'em water for a week or so and it kinda fixed itself.
But thats a cool trick with the vinegar and dolomite, i'll have to remember that.

5 bucks says your PH is a little high check and recalibrate your meter .

calcium nitrate = 15.5-0-0 + 19% Ca total N is 2% so Ca is less then 3% ...also 2-8-4 is a horrible ratio late in flower

no way of checking

Why is a 2-8-4 a horrible ratio for late flowering ?
