I have a 600w grow tent , week 4 into flower
big fan leaves are dying from bottom up
yellowing from inside out
tips are brown not sure if burned
brown spots when leaf yellows
0.8EC
5.7-6 PH
20*C - 30*C temps
40-50% RH

the buds are not looking huge for 600w tent..

first time flowering in hydro system

the EC seems to keep lowering in the water
but the tips of plants seem to be telling me to back off. I'm not sure & would appreciate any advice

maybe I should add more cal/mag?

the strain is Shiva Skunk (mostly Indica)

How much nitrogen are you feeding? Leaves look dark and there is the claw of the leaves?

What nute line? What are you running for amounts? How often are you running your watering? What kind of system you running?

cheers for the reply...


thanks for pointing it out... maybe I added way too much CAL MAG it has a shit ton of N

the system is PVC tube with aero sprayers
spraying 30 sec on and 10 mins off


The A+B fert NPK is 4-4-11.5
Ca 3.0%
Mg 1.2%

the CALMAG NPK is 5.2-0-0
Ca 5%
Mg 1.4%

Usually in hydro you have a higher EC. Yours looks a little low. Dont go crazy on the calmag but adding some will not hurt it.
