Help ..yellowing

Right, I have had the same thing in the past. Don't always jump to a deficiency chart! Look at the basics 1st, bad air flow will do this. It looks saturated too, are you overwatering it? Are you letting it dry out so it feels so extremely light, then giving it an extra day to use the feed in the plant? Get a moisture probe. £4.99 from hong kong. Plants will shed lower leaves at various stages in your grow. That is 100% normal. Personally, I would remove some of the unhealthy lower leaves and get more air flow there 1st. It is essential that you let the soil dry properly, so it feels unusually light weight. Don't panic, it probably has food in already, so don't feed it before trying to improve air flow. Also, make sure the pot is raised and air can get underneath the pot.


When did you feed it last and how much?

I wait 3 days usually between feedings. They seem to be pretty dry and feel light by then
 
See I used to think mine were dry. Then I got a moisture probe. Identifying the deficiency is all very well and still important, knowing the cause is vital. I was overwatering 6 months ago and learned the hard was, til I got some excellent guidance. Now I have zero problems. Mine a like the sahara desert for 24 hours before I water them. I used to wait til they were fairly light. Not drying each time can cause many problems. Root rot, various deficiencies. I also find the plants response after a feed is much better when properly dried. I use air pots, so I can stick the moisture probe through the holes to check. But you can still use them with normal plant pots very effectively.
 
thanks stealth...ill def look into that probe :Sharing One:
