Hey guys
I just find out about this place doing some research as how to solve my flowering problems with my autos.
I will answer the troubleshooting form that I find to be very nice.
What is your experience level? (first timer, novice, experienced...)
I hove some experience with photo plants, its my first time growing autos.
Your Equipment:
.1) Type and wattage of lights. (MH, HPS, CFL's, tube fluorescents, LED's)
250W HPS from veg to flower.
.2) Distance from tops?
About 20-30 cm
.3) Reflector type? (cool tube set-up, bat wing, enclosed reflector, bare bulb...)
Bat wing
.4) Is there a consistent fresh air supply?
My grow is inside a closed room, unfortunately i cant have a continuous air flow system for the whole room so i try to change the air once or twice a day letting the door opened for a while.
.5) Do you have an exhaust fan and a circulation fan?
I use an extractor with a carbon filter pulling air off the grow tent and a small fan inside the tent for air circulation.
.6) Schedule?
As it's been very cold where i live, i have been running 20/4 to prevent very long cold periods at night.
Your medium:
.7) Specific brand and type of soil, (coco, peat based soilless...) and anything you've added to it. (vermiculite, perlite, worm castings...)
Substrate: Atami Janeco Light-Mix
.8) Size of container.
7L
Your nutrients and water:
.9) Source of water. (tap or filtered) What's it's ph?
Not filtered tap water, ph 6.7 to 7. Where i live tap water is considered very nice for
human consumption.
10) Method of checking water ph. (ph pen, test strips, aquarium test kit...)
ph pen
11) Method of adjusting water ph. (phosphoric acid, white vinegar, hydrated lime, PH Up...)
Generaly i adjust by adding a bit of ph 5.5 mineral water to low ph a bit when i use pure water.
When watering along with nuts the solution stays around 6.3-6.5.
12) Specific brand and N-P-K ratio for each bottle. List dosages (quantity per gallon) and current feeding schedule.
I use the Guanokalong liquid ferts and the powder, but at the begining i fortgot to mix the powder into the soil. When i noticed one of my autos was already in 2 weeks of flower, the others were still in veg, so i top dressed all the plants in a desperate move to try to save them all from suffering from lack of P.
My feeding schedule was:
Veg
GK Grow - 2ml/L once a week
GK Taste Improver - 10 ml/L a week
Flower
GK Bloom - 2ml/L once a week
GK Taste Improver - 20-30 ml/L once a week
Water dosages: around 900 ml to 1,2L for each plant.
13) How often are you watering between feedings, and how much per watering?
I feed 1 time a week, water every two days.
14) Any additives or tea's? (Superthrive, CalMag, molasses, Mother's Earth...)
I top dressed with dolomite a couple of times during veg.
15) Are your ph levels stable, or do they fluctuate?
I believe it's stable.
16) What is your ingoing water's ph? ...your runoff ph?
ingoing 6.5. runoff 6.3
17) Do you foliar feed? If so, with what, how often, and at what time do you spray?
Sprayed once with a bit of neem oil.
Your growroom:
18) Indoors or outdoors?
Indoords
19) What size of closet, room or hut?
60cm x 60cm x 160 cm
20) What are the temps and humidity levels while lights are on? ...With lights off?
Temps are around 23-28ºc and 50-60% humidity lights on / 14-17ºc and 70-80% humidity lights off
21) Have you seen signs of insects in the growroom?
No signs at all.
Your strain:
22) What strain are you growing? (Indica dominate or Sativa dom?)
No
24) How old is the plant?
25) In what life-cycle is it? Vegetative, pre-flowering, flowering, rippening?
They are all passing from pre to flowering stages, except Auto Kaya that is rippening.
26) From seeds or clones?
Seeds.
What do I need help for?
As i said, i forgot to mix the Guanokalong powder so i had to top dress at the pre flowering stages.
All of them started yellowing at the first week of flower, from the old to the newest leafs.
Auto Mazar week 6
Auto mazar now (week 10)
Auto Skunk week 6
Auto Skunk now (week 10)
Also i noticed some signs of Calcium or Magnesium deficiency in all of them.
The GK taste improver that i have been using since veg has 1% cal and a bit of mag, also i top dressed them with dolomite a few weeks ago but still..
I didin't find any organic calmag in my region to buy unfortunately.
Other thing i should mention is that i didin't add any more perlite into my mix, i really thought that the mix had enought perlite and coco , something that I really regret now, my soil is too compact after watering lots a of times.
I don't think i can save them and recover to a health green until the end of flower but at least i want to know the big mistakes i made.
Thank you all for the attention.

hey Balthor--...more than one thing happening here I think,...I looked up the fert's, and noted the liquid bases have no P in them, the sole source is the powder, right? I didn't see the "taste improver" listed at their website-
--no idea what it is, or what's in it specifically,.... Bal, get us some nice whole plant side shots please,... I'm with Nammy, some of what I see is N defc. in those uniformly pale lower leaves, but the mid-uppers look like S defc. to me,... any analysis info on the labels about S content? ...the dark necrotic blotches are less certain; Seems there's plenty of Ca in the formulation, so next likely is atypical P defc symptom.... if all of the powder is just sitting on top, it's probably not getting in there fast enough,..Organics need time--and solid microbial life-- to break stuff down into available forms,...I don't see Mg defc. so far,... The dolomite is too slow acting to be of much help (slowest of lime sources; Ag lime, oyster shell powder is faster acting),... As for pH, testing straight run-off alone isn't going to give any kind of accuracy... this method is full of potential measurement error sources,... have a look at this methodology and calculation for r-o testing-> ( 
-- this will be an issue with the r-o pH test method unfortunately... Water logged soil is something plant roots despise,... 
... the S is the worse problem of the two,...
happy to help Bal'!
