1st Time Grower, DWC

4/19 After talking to some fellow growers on here (Roberts and Unkraut) and getting some needed advice I realized I was doing a few things wrong. I was mixing nutrients at 1-1-1 and not 3-1-2 npk. Which is why everytime I tried to up the nutrients the plants were unhappy and kept having burnt tips. Like I pointed out last week I'm measuring EC instead of ppm now. And monitoring PH and EC . I'm also mixing nutrients based on EC instead of ppm or just a standard measurement. 4/20 I found root rot in all buckets. I emptied buckets, put just water did a hydrogen peroxide treatment of 1:1 for 5min soak. And I mixed a light nutrient solution of 4ml gro 2ml macro 3ml bloom 10ml hydroguard 2ml Rapid Start To 3.5gal Plants reacted badly to peroxide treatment. I made the light solution to help recovery. 4/21 plants recovered from peroxide treatment. Going on advice I got from a fellow grower on here Roberts I pruned the root rot off and did a root pruning on all just leaving a inch or so of roots in water. 4/22 mixed 0.30ml/L GH Flora Gro(N) as foliar spray and sprayed them down at 5:25pm still in dark until 6pm and turned fans off to help absorb foliar spray. Mixing new solution tomarrow. I keep a grow log here https://1drv.ms/x/s!AmTQ-7u9iyH6kBCjnqwlkbnRSSDi I been dealing with high tent temps. And I target 73°F and tent has been topping at 80°F to 81°F. Bucket temps have been in 74°F to 75°F. I think that contributed to the root rot. 4/23 4x4 mix nutrients a different level Micro 0.5/L ×13.2=6.6ml Gro 1.0/L x13.2=13.2ml Bloom 0.75/L x 13.2=9.9ml Cal mag 1/L x13.2= ml14 Rapid start 1ml/gal.=4ml 14ml hydroguard
