help!! leaves turning yellow then brown then fall off. what could be the problem?

haven't feed them nutes.. haven't watered the soil for almost 2 weeks only spraying the leaves at night before turning the lights off.. spraying with buttermilk, flour and water mixture coz of the spider mites. that's why you can see on the pics white powder.

I can hardly understand a word you say.

Why haven't you watered the soil in weeks? You should water the soil when it needs it, wait until about the top 2" is dry before you water again. Looks like it could use some N, maybe some fish fertilizer.

zoOt is a jejemons. hhaha. i think he means i should give water and give nutes now..

@Catchin, i haven't watered my plant coz 1 of my plant died of over watering and after that i was scared to water the plants again.. i was thinking i would water the plant when the leaves starts to droop a little but they didn't so i never water.. and i spray the leaves every night i was thinking maybe they will be fine.

and now i watered them the soil dries very fast for like 2 hours. should i keep on watering till the soil gets a little damp

Matak: you can use Paul James's 'finger gauge method'; stick you finger into the dirt to the second knuckle and if it's dry down there water it. You can get a dampness gauge from most hydro stores for about five or six bucks to do the same thing or invest in an Eco Pot that has a built in reservoir and it's self watering. But when you have yellow leaves falling off you're stressing the plant. That stress may have caused irreversible damage that may be apparent in about another month and a half. I hope not, but we'll see. You might refer to Cervantes, Rosenthal or SeeMoreBuds in the future. Please keep us posted on your progress. HSA

its usually nitrogen if they yellow off, give it nutes that are high in N
