Cause of yellowing

[phillykid]

If N def causes yellow leaves should the problem subside alittle on its own when flowering starts? seeing that the plant dosent need as much N as it once did in veg.

No, it will get worse. You should always fix any nutrient problems before starting flower. Flowering nutes have very low N. You have to withhold N to get the plant to flower properly, but it still can use nitrogen. The leaves may yellow towards the end of flowering, but growers who have their feeding program really dialed in do not have this problem. The final repotting when you are going to start flower should include some rich organic material that the plant can slowly use.

how long untill i should start feeding them again? i am using an organic fert (liquid) says 1 or 2 ml per liter, (8.0-2.0-6.0), i was feeding every 2 days, but i now realize that this was too much. any suggestions so i wont get this ph/ burn problem again?

[psymin]

just checked pH, was 6.7.

[GatzBurst]

still a little high, but better. 6.0-6.5 for soil.

How do you adjust the ph of the soil stinkyattic? I know how to test runoff, but then how do you fix it?

[psymin]

i been adding lime to the top soil little by little untill the ph was higher
