ILGM Wedding Cake Autoflower 3gal hempy

Had a good week of growth and flower development. The branchy pheno that was not trained topped out at 32", just two inches shorter than the stretchy pheno. Currently the branchy pheno is finishing its full first week of flower while the stretchy's are entering their third. I switched up feeding schedules this week and fed the stretchy phenos with plain water twice and fed once after after noticing some slight burn on the leaf tips. The branchy phenos I fed once and then followed with plain water but they showed signs of phosphorous deficiency almost immediately after skipping feed. I will be syncing feeds and going with a full week 2 and week 3 feed when the reservoirs run dry. These girls are sucking up over a gallon of water every day and a half and loving it!
