So I did more reading and apparently now its nut burn so i flushed my ladies with the rite PH water and they've been fed twice aday for 10min at a time on just water with no nutes at all but there still getting worse.... Please someone help

looks like PH..........let them dry out between watering what are your temps?

Temps are 30 C in the day and cold at night... Not sure on the night temps... The lights are on from 8am till 8pm the first feed is 08:30 and second feed is 17:30... What do you mean it looks like PH? the PH is spot on... I'm sure it is.. Hold on i'll go check

Thanks for your reply

What are you growing in? Ebb and Flow?

I'm not sure if I'm honest... I bought a hole set up (8 pot wiliam system an everything needed) and got some soil and these ball type things... Sorry for my ignorance whats Ebb and Flow?

Thanks for your reply

...looks like your locked out (salt buildup)...what kind of fertilizers are you using?

your plants are starving to death obviously

This guy is right....
K deficiency among others like P and calcium...
Flushing the medium without replacing nutrients creates a bad osmosis effect on the plant....
Feed nutes ASAP!!!
And don't be scared to step the dosage up...

Flush heavy, then feed nutes. It will take a few days to notice it bouncing back...its gotten too many nutes....so now it is absorbing none and is starving

Ok guys as soon as I read this this morning I ran upstairs and fed them.... Fingers crossed they'll be al rite

Thanks loads guys for your input and help...
