Vains turning yellow??

[Jdcollins86]

Like the tittle says my vains on a incredible bulk are turning yellow?
She's about 4 weeks in to flower.
She's in pro mix hp
She was fed about 6 days ago at 820ppm and watered yesterday the Run off was 5.9
I'm running a 1000w hps and 2 marshydro panels for extra spectrum. I've never have had a problem with light burn. But could this be bleaching? Or am I be paranoid..

I rearranged the plants put the small plants closer to the panda film. Maybe less hot spots....

If you are PH your mixes ( feeds and water ) there is NO reason to check runoff.

If you are watering to the " point of runoff " EVERY TIME just to check runoff , that is why things will occur. You shoot yourself in the foot by " excessively " running water thru container to check runoff . All you are doing is " leaching / flushing " the soil .

If you have your feed correct BEFORE then you know when there is a problem created from feeding or some other means , then you can correct.

During flowering , the leaves will change , fade , die off , spot , burn . Which is normal as the flowers are the main attraction , not the leaves and branching anymore. As long as flowers mature , you are golden. Worry more about : P and K deficiencies during this stage than anything else.

Thanks for the lengthy reply. I've been letting the plants dry out damn near completely before I feed and or water. My understanding was you wanted a 20% run off when watering to get rid of excess salt build ups. This grow has kicked my ass honestly... multiple factors, plants got burnt and I ran out of room in the veg room,so they had to go into flower. Then I had a nasty thrip infestation, and I've been out of town a lot for work.

Great explanation by Budzbuddha. I went through what you are going through. I went from growing dank weed to crap for two grows because I read like you that I should have 20% run off in soil. I ended up with a low soil ph problem. Calcium lock out causes necrotic spots on the upper leaves and is usually one of the 1st signs. Once I went back to my old way of watering everything went back to normal. Good Luck!
