Hello You've definitely still got time to make some corrections. If you were able to get the ph meter back on track go through and run some plain ph'd water and wash some of the excess out and then bring in a low nutrient level just to add a small bit of nitrogen back in and get the pk back into a level amount. Maybe try running the ppm a little on the low side for a week, bring most of the nutrients down .3 -.5 except for the flora nova.👍

You're in a hydro setup so just cut the PK back on the feed. Looks like you're down to the last week and a half anyway. Don't go crazy, just cut it to the proper amount and continue on

leaf tips #2 Hi, continuing the previous question. pH runoff was 6.1 So I decided not to flush and gave it CalMag. Since then yellow tips doesn't spread any further, but the fan leaves on lower branches become fully yellow and died. Does that mean problem is getting bigger and I should flush?

Yellow Colour Some leaves have been turning yellow. Especially the lower ones. I thought it was a nitrogen deficiency as I didn't give the plant any nutrients till 2 weeks ago. Now I am feeding her with Biobizz nutrients according to their table. Should I be worried? Any recommendations?
