whats wrong with this plant?

hello all i have a big problem... i'm doing hydrow and this started last week.. i put my plants in flowering last week and i still had the 4th week vegging nutes in the 5g bucket dwc.. well since i notice the leaves was dieing on me i give it a flush with strait tap water for 24hr then i give them the first week flowering nute.. i'm using G.H.3 FLORA-GROW FLORA MICRO FLORA BLOOM
AND SOME CAL-MAG 30ML 30ML 50ML
25ML
i did the the flush yesterday 12-12 and give it fresh nuts today.. i don't know yet if i fix the problem,but i'd like to know what i did wrong.. the temp stays 70 78 the humidity stays anywhere from 39 50... i have a fart fan bringing in fresh air and a (furnice) fan can't spell it.. lol pulling out and a little house fan.. any advise would help me so i don't do it again..:stoned: :stoned: thanks:) 1.00 MB (1,053,740 bytes)

PH?

i haven't really seen anything like this, sorry, but i am sure you can find (or someone wil send you a link) some sort of chart or guide describing your plants' ailments so you can figure it out.

thanks:) but i don't think it was the ph cuz i stayed on top of it.. would 5.4 be to low? i kept it at 5.4 when it got to 6.0 i brought it down with ph down or change the water..

thanks dutch love.. somebody will now.. lol (hopefully)

I always thought ideal ph was 5.8 except in the later stages of flower. don't know if that is your problem tho....they really do look pretty chewed...you're not spraying the leaves with anything are you?...good luck...

thanks weed 4 ur apply:) i have'nt been spraying them,but i did have my ppm up to 1300 1400.. i lowered my ppm to 1270 hoping thats the problem. if it aint that i don't know.. i'm new to hydro hopefully i can get her under control..:confused: :confused:

hello again:) i don't know if will help u,but i notice the problem is more on the older fan leaves..i've look through some pics and it favors a Magnesium problem. i use 25ml per 5g of cal-mag... if it's a mag problem how do i go about fixing it? i have some epsonsalt and some lime i just don't know how much to use or what way to use it.. any advise would really help.. thanks:confused: :confused:
