Dying 4 weeks into flowering

[djrico]

Hi,

I have a problem with my scrog plants. I am growing GDP clones in fox farms soil. Light is 400w HPS. They are have been getting a 2m(.4 tsp)/gal of fox farms tiger bloom. Recently the leaves started dying so i flushed them. 3 days later its worsening. PH is normal @ 7. They are abot 4 weeks into flowering. Here are some pics. Is it nute lockout or a Mg Deficiency?

Please help me save my christmas present

Looks like overwatering and/or a lack of ventilation

Hey man
I'm not an expert, but I'm sure this has something to do with nutes
either they didn't get enough N early in flowering

I also use the FoxFarm lineup as well, and I give my plants Grow Big for 1 - 2 weeks in early flowering, and then when I give them Tiger Bloom, I'm giving them at least 1 teaspoon per gallon of water... they can handle 2tsp no problems... it seems like maybe you can give them a little more. It's good to start off little and work your way up but I'm pretty sure they can handle more than .4tsp / gal of water at this point in their life.

try giving them a dose of GrowBig with your next nute watering, would be my suggestion.

at first glance i would say PH lockout and lack of nutes are creating alot of deficiencies

try taking pics with the HPS off so we can get a better look at her

doesn't look good though her root system is probably not doing to well
how often do you water and how much? how long have they been flowering?

 

[djrico]

they get watered ever 2-3 days, about .5 liters of water. PH is normal @ 7. Is there hope?

is there any air flo in there? or is it a cllosed cab with just fans??

i would let them dry out. then flush. and leave the door open so fresh air can get in. also go light on the food next time you decide to feed. and i think they should be ok.
good luck

like the guys sed under feed or over feed
or bud rot check the stems
i would flush her out with ph 6.5 .....do u use ph down ?
if so its not for soil as it kills most friendly things in the root zone
so if ya are using thatuse lemon jucie instead of vinger to lower ph

I just flushed them last night. There is plenty of air flow. Should i start using the fox farms fertilizer as well as the tiger bloom? to help boost the nutes? is there hope?

According to their feeding chart you should be using 2 tsp of Tiger Bloom per gallon and 1 tblsp per gallon of Big Bloom.
You should also have been giving them 2 tsp per gallon of Grow Big for weeks 3 and 4.
Your ph should also be between 6.3 and 6.8.

should I implement the above slowly? or leave it

i have not heard about ph down is not for soil! i experienced lots of problems with a grow that i was using ph down with every watering/feeding and they never really fully recoverd. does the same go for ph up? and if so, what would i use for a ph up in soil?
