Yup four weeks yesterday.. On feb 28 they went under a 600 watt hps prior to that they were vegging under a t5The girls look nice are you sure they are only 4 weeks are they auto strains?. They are using up the Nitrogen thats why your leafs are yellowing. If your only in week 4 then you need to add a bit of Grow Big. Its not nute burn they look very healthy just not enough Nitrogen.
I feed them 1/2 doses the amount the fox farm feeding schedule asks for.. The 1 tsp of Cali magic also.. Should I up the amount to 3/4 doses?If its only 1 month of 12/12 you probably need to feed them more. Might be short on N or Mg its something thats mobile. Assuming ph and EC of your soil is ok, I would up the amount of your grow formulae a little bit.
Strain is lavender.. And purple alien oglook great..but you sure you counting right? looks like theyre dying off already.
what strain? og kush?
I have to water them every 2 days.. I wait until the pots are bone dry and that's every two days....I think your problem is Nitrogen defficiency, Magnesium, Sulphur, Iron, Calcium wouldn't hurt either. Yellowing is symptomatic of flowers that have utilized their reserves of Nitrogen. You are too early into flower to be this color, green is needed for growth and energy production. PH may be off or your strain has a big appetite.....what are you feeding them at? The plants look productive and vigorous.....this can cause early yellowing because they ate all their food quickly.....at this rate everything will be yellow and flowers will not grow to potential.
not sure where you are in the foxfarm feeding schedule.I feed them 1/2 doses the amount the fox farm feeding schedule asks for.. The 1 tsp of Cali magic also.. Should I up the amount to 3/4 doses?
Thanks vapor..I'm in week 5 of flower using Fox Farm nutes in soil my Tuts are just chowing the Nitrogen. With other strains I usually dont have to use Big Grow after week 3. But Richard keep it up and Great Job your gonna have some nice big dank buds.
