Barneys double up

Going into week 4 and there both developing pistols, DSD starting to produce trichomes already. Both seem very happy, healthy and strong. Day 29- watered with micro, grow and rhino skin at 1.5ml and bloom at 1ml per 2l of water. (29/12/20) Day 31- watered with ph’d water till run off. Day 32- there both wilting quite bad and some fan leaf stalks are going red, it looks like a phosphorus deficiency to me so I’ve given them both 2ml voodoo juice, 1ml bud candy, 3ml micro and 3ml bloom to 2litres of water. Fingers crossed that gives them what they need to bounce back. I’m obviously being too cautious with the feeding and need to step it up sooner... a mistake to learn from! Day 35- They seem to have just about bounced back so I’ve removed all the fan leaves showing the deficiency’s, pre soaked the soil with ph’d water then gave them another feed with 1.5ml voodoo juice, 1ml rhino skin, 2ml micro and 3ml bloom in 2 litres of bottled water.
