spotting on leaves. +rep for help

i seem to have this ongoing problem with the leaves where they spot, get more spotty, then die. im on day 13 of flower, i water with distilled purified water. any ideas?

Spider mites. Any number of safe sprays you can use!

Check the marijuana plant problems section. Youll find more help there. I think its a defficiency of somekind. Probably phosphorous or potassium.

looks like you may have spider mites bro

That is a whitefly or spidermite problem. I'll bet more on whiteflies, as I don't see mention of webs all over the leaves.

Soapy water spray, keep that up two or three times weekly for two weeks.

spray with neem but hurry the flowers may die sweetie.

its not bugs. i should have mentioned. theres not a single bug ever. never saw one and i looked super close many times. a deficiency? it kinda looked like maybe burning? or maybe a ph problem

It is magnesium sweetie. it will look like a def. of nuets

hmm, any nutrient recommendation. im using humboldt gravity now, low amount though. is there any product at homedepot or wal mart that would help

MagiCal or cal-mag plus...

feed them...

It is either a Calcium or Magnesium deficiency. One can lock out the other, so it's like a see-saw with those nutrients.

If you are using tap water, it is most likely a magnesium def. caused by the high calcium content of most tap water... correct it by adding 1 tsp of epsom salt (you'll find it in the pharmacy section at the grocery store) per gallon of water.
