Help pleaz--red spots spreading----i got pics---

IM A NEWBI AT THIS , I HAVE 2 PLANTS IN DWC. 18 GAL, CHANGE EVERY WEEK, I GIVE IT PURE BLEND BLOOM, LIQID KARMA, CAL MAG. THE LEAVES DRY UP AFTER A WHILE.THERE BLOOMING RITE NOW. PLEAZZ HELLLPP!!!! ILL GIVE U MORE INFO, JUS REPLY MAN PLEASE.......

first of all. i just commented on your other thread you started. second, dont start multiple threads like this

but ima say a zinc dif. lower you ph a lil bit. should be round 5.5-5.8 in dwc, if i remember correctly.

actually i think you want it between 5.6-5.8

i gotta little ph liqid , is dat fine?

you dont have digi?

no rite now im using dat liqid ph reader,is dat accurate?

ha. maybe to 1.0 ph. you NEED a digi ph water meter. get ph buffers and keep it between 5.6-5.8 to prevent and correct def. i think zinc is the first to get locked out when it varies from that

it wouldnt be nute burn?

naw. nute burn they will dry up. im betting its zinc. its similiar to Mg def but no yellowing of the leaf. also do you foliar feed?

wats foliar feed?

spraying fert water on the leaves. it helps with def but can burn your plants if you do it with lights on. do it right before lights out. as for zinc? galvanized nails have zinc. maybe shake them in distilled water. or soak em. then spray yo plants. but get your ph, with a digi meter, which will run you bout 75 bucks, but is a must in dwc and any hydro. ( sorry for the comma splices, sooo muuuch haaash) get it stable at 5.6-5.8. i wouldnt doubt it if your ph was like 6.2 or something. that liquid ph test is only good for pools to see if they need buffer or acid to keep it neutral. if you do this, it will make your grow go along with so much more ease. make sure you have all of your minerals you need covered. esp cal mag.

whats this folair feed called when u buy it at the grow shop?

haha its water in a spray bottle. you puts some nutes in the water, 1/-1/8 strength, and spray on the leaves. WHEN LIGHTS ARE ABOUT TO GO OUT. thats crucial. but for zinc, galvanized nails have zinc. maybe make a nail tea? then foliar feed with it. may help

what kind of nails are we talking bout here? nails that you hammer in walls?

Dude from these second set of pictures, looks like a fungus or something, I thought your leaves were yellow from your previous post, but I was mistaken due to poor quality of the photos, pretty sure this is some sort of disease

would it be air fungus? or because water puddles? i have my ac cooling the room down, can it be bad air going in?

no galvanized nails. buy em at a hardware store. and if its a fungus what do you recommend. mold= sulphur dust. fungus= neem oil? or is there some other organic fungicides? actually i take back the neem oil. that ones for buggies. jeez. way too high. haha.

ha ha it happens. im hella high too. hey i appreciate u helping me...

what causes these fungus?
