Need a pick. Don’t flush. Based on the description you have a nitrogen deficiency. I like a flower booster in week one—- like jacks 10/30/20— gives them a good feeding during the transition

Post some pictures so we can see what is going on. My first guess would be a nutrient deficiency. Why do you think you need to flush? Did you over fertilize?

What may caused the issuesChecked the runoff and confirmed 6.2PH and 130 ppm on water.
checked on my Tank and same was happening.
so gave a 603 ppm solution of cal/mag. Grow A+B perfect pH connoisseur, H2O2 at 5.8 pH.
Will await for results.
i think at week 3 theyre supposed to eat at least 600 ppm?

Fan leaves turning extremely yellow late flowerHello. Day 61 of flower, Green Crack 2.0 by Humboldt seed organization. Soil based. All of a sudden all the fan leaves are turning yellow. Trichomes are clear, no exceptions. Is it from finishing or did I mess up watering/nutes in the last couple of weeks? Thanks in advance.

Yellow leaves from bottom upwardsI have yellowing leaves from the bottom up. It resembles either N deficiency, MG deficiency or both.
Growing in soil.
PH is between 6.5-6.8.
Feeding 1ml/L fish mix and 3ml/L bio-bloom every other watering.
I tried adding cal-mag with N at 1ml/L and if anything it's got worse.

Starting to fade? Or nutrient deficiency?One of my plants has several fan leaves that are turning yellow/purple, and I can't tell if it's low on N or starting to fade. The plants are 2 days into week 5 of flower with a 9-10 week flower period, so it seems a little early for it to be turning colors like this.

Outdoor northern lights auto yellowing earlyWith 3-4 weeks of flowering still to go, how worried should I be about rapid yellowing? I have kept feeding, i know she is rootbound and I havent checked pH. Do some plants just yellow earlier in flowering or should I act?
