my larger auto fem has started developing yellowish dots on 3 fan leaves.a few have said mites, but i checked the underside of the leaves and i saw no sign of them. from what ive read maybe a calcium deficiency starting?

after closer inspection the spots are brown with yellow around it. its like as if i got something on the leaf itself? they arent holes and i looked on the underside with a magnifying glass.

some sort of deficiency due to ph being off or lack of the nutrient. looks like calcium to me. heres a page i used a while back http://www.growery.org/2991/Diagnosis also heres another http://www.420magazine.com/forums/problems-pests-disease-control/81275-cannabis-plant-pest-problem-solver-pictorial.html

if you are feeding it some sort of calcium magnesium supplement your ph in your water may be off. in soil i use lots of lime and never have this problem anymore about 1 cup per gallon of soil when im ammending it with perlite and other additives but some strains eat more than others or maybe one nutrient got used to much of and its locking another out.

i would maybe leech it or feed it depending on what you have been doing.

she gets fed tomorrow morning. sorry im a newb lol what do you mean by leech it?
after reading that i think its a feeding problem, i have half coming into late flowering while others are getting into the early stages and i will admit most of my attention has been on those 3. well see come day after tomorrow.

this plant is much larger then the rest so i probably havent been giving it the right amount it needs. i checked the nutrients and 2 out of the 4 have calcium in them., and from what i read off your posts, that should clear it up. So i will feed them in the morning and see what happens.

lol i was freaking out after a few ppl mentioned mites lol. So thank you, i havent had any problems up until now

calmag from the looks of it just the first thing that pops to mind

should i flush that container and then feed it accordingly? or do you think trying to feed it and make sure its getting it will fix it and thank you tek you've been very helpful every time i got a question. your input is appreciated.

No flush. Just feed...those leaves might/probably will remain $hitty looking. Just watch to make sure it's not progressing.

alright. i checked the plant pretty well it only seems to be on 3 of fan leaves kinda centered on the plant.

yeah just remember that the damaged leaves will not repair themselfs just watch all new growth and make sure it doesnt keep progressing quickly.

its probably used up all the calcium and thats locking the mag out
its probably just a nute whore and will take a larger or more often dosage of calmag to keep happy
there is a rather large pheno swing on most auto's it affects nutrient tolerance and plant needs as well as looks flavor etc.

You spray those plants with the lights on by chance? Looks like calmag but at the same time looks a lil diff. I just like ruling other things out

it seems to have progressed onto some other fan leaves still kinda on the center of the plants. Im going to try and get some calmag today if i can get to the store before it closes. if not definitley tommorrow. and that should clear it up? also should i give it to all of my plants or just to the plant that needs it.

also started to notice some discoloration on two leaves on another one but its further into flowering. im going to keep an eye on it but do you think its the start of cal def also or just the leaves starting to turn with age, only a couple more weeks till i flush.

how badly could this affect my harvest if i cant get it under control.

you can use epsom salt too
its really cheap and can get it anywhere

the leaves on a dialed in plant will stay healthy until they yellow from flowering and fall off
if its getting patches / spots / necrotic area's or any discoloration other then changing to a dark green or blonde color depending on strain of course
then your having some kind of issue be it ph nute burn , nute def , or a heat / ventilation issue or hot spots

one the plant the discoloration has started on, i guess someone could consider it blonde. im going to keep a close eye on it.
Should i give all of the plants some cal mag? and if this doesnt fix the issue, is it safe to say that its a ph issue? and that its just locking out what it needs?

Its only in that area, while the rest of the plant is all green/dark green with no signs of stress.

it could just require more calmag then the other plants wont know if its a ph issue until you ph the water going in and also the water coming out
its probably just hungry the others might benefit from a feeding also

this is what i went and got. i gave the plant with the deficency 1tsp/gallon and the rest of them got 1/2 tsp/gallon. that i split up amongst the remaining.

which leads me to one more question. i have 6 plants in flowering 3 in the early stages, and 3 in mid to late. i mix up 4 gallons of water for for the earlier ones and 4 for the later ones and divide it amongst them as equally as possible. should i be giving them each their own gallon? maybe thats why it started to get a deficency?

I don't know if it is to early to tell yet, but the cal mag seems to have stopped it from'm progressing to the rest of the plant, but the leaf that it started on has gotten worse. I gave it another tsp of it this morning and will be giving it another dose tomorrow morning when I feed them.

I'm hoping this does the trick as its on my biggest plant which would definitely yield more then the others. I'm going to be picking up a digital ph reader. If it is a oh prob should I use the oh adjusters of the brand I'm using or will pHup/ph down do the trick
