Hello im currently in veg stage plant is about 40 days old under a 250W CFL 6400k (first 14 days in 4L pot and after that repot in 15L air pot)
Temps are quite high like 27-28*C and humidity like 30%
Soil BioBIzz AllMIx + BioBizz nutes( bio grow, bloom , Heaven , ROot Juice , Alg-mic, Fish mix , Top max) and AN' piranha and tarantula that i also mixed in the soil
I dont Ph my feeding coz its all organic and the soil buffers its self ( done a Ph runnof test to be sure its not PH and its 6.7-6.8 ) also i dont use tap water ( my tap water here is PH 8.5 and ppm 700-1000) i use botled water with a ph 7.3 / ppm 100-150
my feeding till now was like this
day 1-7
plain water

day 7-14
Root juice (1-2 ml/L) + piranha and tarantula

day 14(repot)
first 2 feedings just water with Root Juice (2ml/L) + piranha and tarantula ( i have to mention here the quantity of the water was 1L for the 2 first feedings)
3rd feeding was 3.5L of water ( big pot drinks lots ) Root Juice (2ml/L)+ Bioheaven(2ml/L) piranha and tarantula

afther this i stared to add with each watering for half a dose each bio grow and fishmix
BIoGrow(0.5ml/L)+fishmix(0.5ml/L) +rootjuice(2ml/L) every other day
and between
ROotJuice(2ml/L) + Bioheaven(2ml/L) + algmic(1ml/L) ( all mix has MG def .... happend before) but im confused now
i water twice a week ( summer now ) low control on temps but it has a lot of airflow for these hight temps

my feeding is done by first aerating the water for 12h then adding the nutes +piranha and tarantula and let them brew for 24h and then feeding
i feed half of my mix to the plant.... let the plant absorb for 1hour and then feed the rest...

my problem here is realy i dont know why the leaves look like this... im confused and when i get confused i start to overdo things ( stoner habit i guess :P ) and im afraid im gonna do more bad than good
my first post also so feel free to flame/advice/punch(to wake up) if i dint get enough info here

im planning to switch to 12/12 when i reach the size of plant i want to hope for a 3-4 oz harvest
oh ... strain is

Look s like Mg to me, not burn. You have a vigorous plant there and it's running though micro elements to grow that fast. Not very bad at all so a little cal/mg and they'll be back to normal.
 
thx for the reply tags420 i tought that would be the prob so yesterday morning i gave them a good feed .... (bio grow 0.5ml/L + fish mix 0.5ml/L) + algmic 2ml/l ( the cal/mag) and i think they got a boost looked better but dunno if the problem is solved ... time will see .... here are the pics after the feed

The timing of it occuring at around 40 days would point to cal/mag deficiency, but I would like to know the ppm of your mix. Seems like a lot of food to me and you could be pushing the limits on nitrogen. Just a thought. Good luck.
 
thank you for your response Jimdamick :weed:
i dont measure the ppm beacause i use all the bio-bizz nutrients and they are all organic and i know in organics un can't measure the ppm accurately ..... the water im using si bottled and the analysis is like this

Na - 2,84 (mg/l)
Potasium - 1,18 (mg/l)
Magnesium - 2,55(mg/l)
Calcium - 9.85(mg/l)

PH 7.35 ( tested )
EC 0
ppm 25-50 ( was tested with a blue lab combo meter) -----this is just the water .....

i thought also i could be giving them to much but........ i bearly got to the 1/4 strength of the nutes ....
i used them both because in the feeding chart it says to use half of each (one from molases and the other is fish emulsion)
if u compare the first pictures before/after the feed ... i saw an improvement after i upped the cal/mag dose or just my stoner opinion ..... thats why im asking u guys for an out of the box thinking .
the next time im gonna feed i will use just bio-grow+cal/mag + (bact/fungi)

il keep updating with pictures after tommorow's feed and hope it will show signs for a more acurate diagnose
tell me if u need more info about this and il try to answer as accurately as i can. i wish u all a great day ;)
