I was advised that I have a cal/mag defficency problem with my 3 week old plant...
it had real dark fan leaves....
and then they started to dry and crumble...
it is a lemon skunk from dna genetics.
I have her in a soil mix.
I have another exact same strain, breed, she is 16 days old and she is lighter in color ...I don't get it...
I really want to remove the sickness fom my plant if I can't get past this...
I am going to test the water ph now,
also could this be a result from misting?
Last four pics are of the younger ..obviously...lol
Thank you for your time!

Does your soil mix already have fertilizers in it? That has happened to me before and they were soaking up all kinds of shit I didnt want them to.

Research HERE... From the looks of it, I think it's safe to say that it could be a combination of Mg deficiency and heat stress.

Does this sound like the picture?
Boron

Boron biochemical functions are yet uncertain, but evidence suggests it is involved in the synthesis of one of the bases for nucleic acid (RNA uracil) formation. It may also be involved in some cellular activities such as division, differentiation, maturation and respiration. It is associated with pollen germination.
Boron Deficiency
Plants deficient in boron exhibit brittle abnormal growth at shoot tips and one of the earliest symptoms is failure of root tips to elongate normally. Stem and root apical meristems often die. Root tips often become swollen and discolored. Internal tissues may rot and become host to fungal disease. Leaves show various symptoms which include drying, thickening, distorting, wilting, and chlorotic or necrotic spotting.
Boron Toxicity
Yellowing of leaf tip followed by necrosis of the leaves beginning at tips or margins and progressing inward before leaves die and prematurely fall off. Some plants are especially sensitive to boron accumulation.

What are you up to now?



Your plants are only 3 weeks old. I use FF nutes and won't hit them with veg nutes till 3 weeks. I do use a small amout of BB at 2 weeks. I'm not sure the comparison helps, have you used FF before.



I think your problem is stemming from the nutes and possably misting. Your RH is perfect so I'm not sure why you would mist them to begin with.

I'm pretty sure it was the misting.
The plant with the problem is about 27 days above ground the other about 17.
The younger is not having the problems that the older is.
They are the exact same strain and breed and sex.
I think they can handle the moisture better when they are young(misting)
The older is getting too dense for that...leaves growing on leaves...it's the strains characteristics.
no more misting and we will see...

Whats done is done but I'm sure a week or 2 and you won't even notice. Don't over think it, keep it simple.
