Howdy Kaka Welcome Looks like excess nitrogen to me. What are you feeding now? What is your EC ? πŸ€” ---

Since im not in europe.im in indonesia.normally i feed my plant using hydroponic fertilizer AB.this is my 3rd grow.previously never encounter this problem.my PPM is 1500 and PH is 6.5.i just add calmag yesterday because it is look like calcium deficiency. But i scare i might do mistake by adding it and need advice from an expert here. ---

Howdy Kaka Your pH at 6.5 is too high for me. I would drop it to around 6.0 to 6.1 in flower and check pH everyday. ---

Hashton, you mean 6 to 6.1 is for hydro?im using hydro RWC now. ---

Howdy Kaka How big is your nutrient tank? πŸ€” I would drop your PPM by 100 and see how it goes. I use EC pen and it has been fairly warm here so I have dropped my EC from 2.2 to 1.5 over the past few days because I was getting nutrient burn. I add Cal mag in hydro or Coco as required. ---

> [@Kaka](#): > > 6 to 6.1 No for flowering in Hydro that is what I do @ 6.1 pH. Usually in Hydro in veg at pH 5.8 You said your pH was 6.5…too high. ---

Beside from heats, all be good for me and girls πŸ™ let you get back to the OP question here, im just curious if i’ve to drop pH when flowering. I was facing this once back to my first growth and that times i didnt check pH. so let that slide. Thanks for answering ! ---

Im using rwc system that have 5 tank and each tank is 5 galloon.since my problem is clearly because of the PH.i will lower my PH today and see how its goes.thank you hashton.hopefully once i reach PH 6 is gonna be okay. ---

Your ppm should never exceed 900 in DWC. As your PPMs increase you flush and reset reservoir. How much of a ph swing are you seeing throughout the day? ---

May i know 900ppm is for flowering?what about PH? ---

I hope this helps, swings will occur, you just need to keep it within the parameters. ![IMG_2112](https://global.discourse-cdn.com/growingmarijuana/original/4X/6/b/5/6b5c7872883be768cc5cdd9c7a44f96e4df2dd5a.jpeg)
