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

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?

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.

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

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.
