Toxic Salt Buildup in Early Flower

[guerrilla]

hey guys. im writing this as my 16 plants are on day 24 of flowering. over the past week the lower leaves have begun to yellow, and before that most of the leaf tips were burnt, suggesting nute burn. I am growing in 5 gallon buckets with fox farms happy frog mix. Now, lots of lower fan leaves are completely shriveling, dying, and falling off every day. In the bottom of my trays i see white looking deposits..... i fear that i have a toxic salt buildup

being a dummy i've been following fox farms nutrient calender without alternating between the heavy strength solubles and organic nutes. so, i've been giving heavy duty salt based nutes every watering. now, i am experiencing the lockout

so, tonight i painstakingly flushed all of my plants with 2 gallons of tap water. Lots and lots of water ran out the bottoms of the 5 gal pots, but reading other threads im thinking i should have flushed with more water? what do you guys think? when should i start feeding them again, and should i start off slow with light nutes? will this really affect my overall yield? right now the situation seems confined to the lower 1/3rd of my plant and the tops look excellent, but im fearing that the problem will spread.

looking for any help guys. no pics for now, but i hope my description is adequate. thanks

LESS IS MORE!!!! K.I.S.S
U should try and water with regular h20 in between when u feed with nutes.. Remember
the more nutes u give them doesnt mean more bigger better plants.. If they live water them with h20 for a couple of feedings then try nutes.. BUT remember the very first things i typed... Hope it works out for you... peace..

hey thanks for the advice mate. i'll definitely be watering in between nute feedings from now on. wondering if anyone else can weigh in on the issue??

Flush with about 15 gal ph adjusted per 5 gal pot for more confidence and feed then.

Yup sackoweed is right on the money!
Always have at least one plain water to help remove salts left over stuff plants don't use.
If not, like if your watering is far apart you can do this..... feed/feed/water/feed/feed/water

never always have fert with water, always got to have some plain watering.
