Nutes in flower

Ghostknife78started grow question 5y ago

Anyone have any feedback on running high ppm in flower with RO water? Does SLF-100 help flush unresolved nutes? My first grow but I think I'm blowing it, please look and tell me what I'm doing wrong.

Always start with a lower rpm of bloom nutes and work your way to max ec for dirt or for water grows. High rpm when starting your bloom nutes leads to overfeeding and a reduced harvest. Cheers.

Bottom leaves yellowing over last three days. Day 15 of flower.My bottom shade leaves have started to yellow. I am just starting 3 week into flower. Am I having a nitrogen deficiency or is this the normal yellowing. I just started a very light 1-1-2 nutes in my water to supplement. No nutes until now except in soil. See pic

Deficiency?? Excess? Neither?Grown this strain before and had the same issue.. not sure if its a CalMag deficiency entirely. pH has remained at 6.0-6.5 or so in soil and didnt show signs until recently, seemed to have worsened after just two days of only CalMag and Ro water so I bumped up the bloom nutes.

Emerging Issues - Week 9 At the beginning of the week, I noticed the tips of the leaves drying out. Now, one out of the four plants has completely yellow leaves. Could it be due to the increased Biobizz Bloom dosage? For more information, please check my journal. Regards.

From day 50 some leaves of the plant started to turn yellow. I had stopped nutrients due to an overfert problem. So, on day 50 I started with the nutrients again, but in lower doses. 2 week left to harvest. What should I do with this nitrogen deficiency? Should I worry?
