I need help. I’m in later stages of flowering and I found a couple days ago that my leaves where turning yellowish. I contacted my Hydro store and thought it was Cannibalization. When lights came on today I found that on one of my plants, the yellowing had gotten worse and that now I have Brown spots on my leaves. ![20190329_161347](https://global.discourse-cdn.com/growingmarijuana/original/3X/5/e/5e2e54f968b11dda239cc502409f63ccfaca1653.jpeg) ![20190329_161359](https://global.discourse-cdn.com/growingmarijuana/original/3X/a/7/a70e455d2126413937864e61baba4e34a2da029f.jpeg) The pictures improve the color. They’re much more yellow than the image would lead you to believe. Thank you for any assistance you can provide. THANK GOD FOR EARTH MEDICINE! ---

Hi I am dealing with a similar problem I believe it is a high PH in the soil causing the nutes to be blocked I am going to try and lower the PH first thing in the morning using vinegar ---

So I see your in flower During flower the older fan leaves will start to die off just a FYI The ph numbers you posted was that taken from the run off or is it what your putting into the pots ? Reason I’m asking I found ph of ffof to be low when I used it which may not be the case here ---

My runoff ph has always been 5.4 to 5.6. I spoke with my hydro store and they told me that the soil has buffers in the soil that keeps the soil ph balanced. My soil is 7.0. I ph my water between 6.5 and 6.2. ---

Next watering raise the ph of your water in If run off is lower than 6.3 lock outs will occur Try watering at 7 ph To get run off up @Outlawhaze ---

Yeah I am in late flower but I expected the yellowing to occur from the bottom moving upward. Right? These leaves that are damaged are spread throughout the plant. After some research I believe that the cause of the stress is phosphorus deficiency. Now I have to figure out why. Soil issues or Grower’s issues. If it is a lack of phosphorus in the soil should I use a dry ammendment like Happy Frog Fruit and Flower or buy a liquid additive? ---

Good eye @Myfriendis410 I think you nailed it Root bound pots will cause issues that look like ph or lack of nutrients cause the roots can’t uptake the proper amounts @Outlawhaze you should have them in 5 gallon pots at least smaller pots especially and plastic pots tend to cause a root bound issue as MF410 mentioned How far into flower are you ? ---

Will do. I will suggest you take plenty of time in your design. I spent a month or more thinking about the layout and when I built the system I ran it “dry” for a week or more to make sure everything was running correctly. My biggest suggestion is: USE BLACK HOSES HAHA. ---

These are 3 gallon pots. I’m just about 2 weeks away from harvest. Should I transplant at this point? If so does a 7 gallon pot work? Thanks for all your help with my first grow. ---
