hello fellow blades.. heres a few pics of the fan leaves that have yellow spots that seem to be originating from the veins in the leaves.. i increased the ppm of my nutes once I saw this but i'm having PH rising issues that are not getting any better no matter what I do and I am wondering if it's another issue and increasing nutes may be making it worse? the buds are growing but i'm having ph go from 5.5 to 6.8-7.0 within 6-8 hours any input is greatly appreciated, it's my first grow and I really want her to be a success. any detailed info needed can be found on first post on the journal link in my sig.
I had cut some colored roots not long before this in attempt to solve the ph issue, I'm starting to believe it is chlorasis from that but some external reinforcement would be great!
too high of ph will lock out trace and micro nutes flush the soil with good water.. ph around 5 and let them sit for a little bit..and dry out..reduce or eliminate the nutes for a feeding or two. until you get the ph stabilized.. test the soil and make sure its not above about 6.3 6.8 and 7 is pretty high and will cause trace/micro deficiencies and probably some nute burn if you keep adding nutes
for sure it is all about ph.i would say stop feeding them for a week. keep the water ph at 6.0 to 6.1 keep it growing
i'm timid to completely stop feeding them 4 weeks into flowering. i'm going to drop the PPM considerably (from 900 to 300) when I wash it out today to see if that has any effect.
