Yellow leaves

Burning from too hot soil mix. Acapulco Gold is a Sativa that needs a lot less nutrients than other strains. Just keep giving plain water until the leaves grow without burn marks, wait another two weeks then start feeding with half strength nutrients, this is all she will need, even in flowering, half strength. It needs to use up what nutrition is in the soil already before new nutrients are added. If not, the burning will just continue. Fox Farm soils seem notoriously too rich from reports in this forum. Personally I would advise against doing 12/12 from seed, it takes so long and you are better to get them growing properly and vigorously at 18/6 and then switching to 12/12 for flowering. Otherwise it is a bit like driving a vehicle and never getting out of first gear! You will obviously have to feed the Acapulco Gold its own blend of fertilizers and this shows how not all cannabis can need or cope with exactly the same nutrition. Either that or just dilute the nutrients that you are making 50/50 with plain water before giving it to the Acapulco Gold plant. At this stage I can't see the need to be feeding any of your plants with Bud Candy or Terpinator, these are flowering supplements, not grow nutrients. Hope this helps, Organoman.
