this is my first grow so i need some asistance
5-6 days ago i tested my runoff of my 5gallon buckets the soil is pre nutsed from manards.
the plants are 2 months old aprox and now are 3 days into bud.
the runoff was 3000-4000 with ph7.5 so i flushed 350 ppm ph 6.3 untill runoff was 5?? ppm the next day they were yellowing so gave 450ppm3 cups as to not drown after flust and still yellowings geting worse:(

Pictures, would be very helpful.. But with out them all i can say is its been my experience that new growth often is slightly yellow for a bit and green up with age..

But as i said pictures sure would be helpful..


Edit: I dont see anything to be too alarmed about.. But i'm a soil guy atm, so as they say grain of salt and all..
Just keep an eye on them, also be careful with superthrive, i've killed more than 1 plant using that stuff.. KiSS method!!

Peace Out & Happy Holidays!!

what are your temps? day/night? could it be really cold temps? I'd keep checking the run-off, but don't get too low.

mine looked really similiar for awhile, not quite as bad, but I lowered ph & warmed up the room... I don't know which it was but it helped.

I had a similar issue when using CalMag. I use 1/2 the recommended dose of it and the bloom fert.

The yellowing is also similar to what happens in offgassing. Are you using a tent?
 
no its a shed i built from the ground up but ran out of money
i ajusted temps alittle 70-76 lights off and if ac is off it gets up to 85 under lights like 1 foot and 75 ambient when ac is on i can keep temps alot closer70 -75
 
i acualy saved someones crop they were useing cal-mag and they shouldent have becouse they were using tap water and overdoses show up as deficences

I think your ladies have a little too much moisture down in the root zone showing as an iron lock up from lack of O2 and your ph sounds very unstable. Ditch the superthrive and use molasses a few times but watch for OD when applying many things at once. Your plants look pretty healthy and I would back off the additives and get your in/out ph to be a solid 6.5 and your worries will fade away. Happy New Year NS

can i ask why??? thats wierd its 16 on a 8 off or 12on 12 off orsomethign between... why such a wierd schedule??


youd have better luck leaving them in the dark for 24 hour and switching to 12 on 12 off then you would doing what you are doing...
 
24 hydro plants were stunted and trying to get some buds out of them 2 1/2 months 12/12 and no bud to litte ferts then to much i think invested evrything and trying to get something 1 way or anouth
