any ideas on what this is-

I have 10 clones and all have these on lower fan leaves and better yet how to retify--it looks shinny but only wet from dew

I feed 3 part jungle juice by weekly with a monthly dose of cal/mag

pic of entire plant is whats needed

how much in mls per gallon do you feed of the 3part and calmag?

if its one leaf or two down low do nothing

if its down low and working its way up on the plant and getting worse
without a picture id GUESS calcium def

I have 10 clones--gave all a double dose on cal/mag as well as the jungle juice 3 are outside to cut clones---3 are into budding 14 days--4 were put under 12/12 today---after cutting clones from the first 3 outside---the last 3 will go under lights 12/12

double dosing gonna give you double yields in half the time at twice the cost maybe?

shit, i'd triple dose if that worked

next round im gonna put them in a chicken coop so the chickens can shit on them for ferts
11

tell me what the % amounts are for calcium and magnesium for each of the 3 parts of your jungle juice

I already have the npk values

personally

I would mix the jungle juice 3 part like this
per gallon
full strength veg
7.5mls grow
5mls micro
2.5mls bloom

full strength bloom
2.5mls grow
5mls micro
10mls bloom

only use fertilizer every 2nd (or even3rd) watering unless they look hungry then slightly more frequently

tell me what the magnesium and calcium % numbers are and I can tell you how much calmag and Epsom salt will balance the formula

the pictures show a very mild imbalance between calcium and magnesium

careful not to over due it you don't need much they look great

If you just have a few leaves doing that I'd chalk it up to "shit happens". Plants look good you are always going to have some leaf drop down low, perfectly normal.

well its been awhile --the clones have been under 12/12 for 8 weeks or so--didn't write date--- .the buds have really starting fattening up---don't know strain but this strain is slow about finishing------I don't know the strain--it==the mom has been growing 4 yrs now--will be the last time cloneing her for me---I have the 7 clones about ready another 9 clones 2 foot tall and 10 more a week old after rooting----I put parent outside in 20 gallon pot----smoke is good however 3 months is too long to budd for me----also I like afgan --this has to be sativa strain!!! the mamma did good for me---I got probably 70 clones of her in 4 years--

the last pics you posted look great

Yeah thats a pretty clear cal/mag issue. I recently went through something similar. I would flush really good with ph'd water also checking run off.
Then give it a shot of your regular dose of cal/mag, you don't want to tox it.
I also used an amendment called Raw ominoA, its amino acids which help with calcium uptake. Once I did what I just told you I stop seeing spreading within 3-4 days. Also those leaves won't get better, up to you to take them off.

my clones are doing very good so far!!!

here is some pics of the other batch of clones---all these plants are from 1 mother and she gives me 30 clones every year for 4 yrs now!!! here are picks of the 10 clones i took before these--here they are at 65 days budding

the budding pics

what size/type light are they under?

is that a sativa strain? they don't look 65 days

12/12 june 7th----last time around they went close to 90 days they are sativa but I planted a few and a mouse ate labels ---all the clones you see here are from 1 mom----goin into 5th yr---I think this is last round with the ones I have outside and get rid of mom and change up to some afgan stuff.i wish I knew what plant it is though.under a 400 and a 160 watt hps--12/12
