  4. to me it looks like a calcium def or possibly manganese by the pics. often plants develop Ca defs their 3rd - 4th week of flowering, some strains use it more than others. there are many products available to add a boost, calmag is a popular one.
     
  5. your soil is mostly compost, which contains alot of nitrogen in itself, additionally its been pre-fertilized with nutirents to last 5-6 weeks

    your plants is young and suceptable to nitrogen burn & basicaly was double dose fed

    with ph corrected water (6.5-6.8ph) flush the soil 3 times the volume of the pot to leech out the excess ferts

    eg: 1 gal pot = 3 gallon flush

    when you say , 1/4 strength nutes 24-8-16 what are the exact measurements are you using, from the suggested amounts on the box? or what youve learned from another grower

    just water for the next 2-3 weeks then begin to feed @ 1/8 strength to be safe, incase you didnt leech out all the available nitrogen
     
  6. freshman i was typing when ya posted the pics of the whole plant, so i was refering to your initial pics.

    i still think Ca is gettin locked out somehow.
