Deficiency of some sort?

sansebseb · Aug 3, 2014

Sup guys,

I'm new here, yet i've a plant last summer. Anyway, my plant is about 2 months old and is showing signs of a deficiency (i think).

The leaves (mostly on the top) are slowly turning yellow (from the base upwards) and have rust spots.

Here's a pic, thanks in advance for the kindsness

Thats a magnesium deficiency.
Are you using any feed at all?
Get a well balanced npk for the vegation cycle and feed it low doses about every two weeks.

I think cal/mag is a good call. Not sure how much you are feeding her and I can't really see you leaf structure very good in the pics but it looks like there maybe a little downward clawing on some of the tips. If this is what you see, slow down on your nutes as well because too much will lock out nutrients.

cal mag isnt going to fix shit with this one. if it's top down then its a immobile element your plant is missing... not N P K Mg S... its probably easier to feed more micronutrients. either way you should post another picture of the whole entire plant and describe what you are using as nutes.. including pH and PPM. Also, picture is blurry i can't see the lower leaves clearly enough so it would be helpful if you posted something that includes the lower canopy

so the leaves are indeed curling a bit downward and i have been using tomato feedings for a month now, and that once a week.
here are some more pictures too

if i am looking at this angle it looks like magnesium deficiency. so back to the epsom salt or cal mag.
