Stain: 6 Ken's GDP Harborside Clones
Light: 1000w MH
Nute: AN A+B, B52, Cal-Mg, RO water
Plant growing in ph 5.5 - 5.8 solution. EC was gradually increased from 0.8-1.7 throughout 4 weeks veg with no noticeable deficiencies except that the PH runoff was usually higher than what I put in.
A few days ago my PH pen broke. Knowing the PH always steadily rises a little each day, I took a best guess and added some PH down in the reservoir daily... After buying a new ph pen and checking the runoff a few days later, My PH was at 2.9! I must have added too much ph down during that time. I did an emergency flush and ran a light H202 ph'd solution for two days.
Overall the plants still look pretty healthy, except for these 3 leaves. It's in the middle of the plant. Can someone please help me diagnose what lockout it is and if it will spread to the rest of the leaves/plants? Any help and/or suggestion is much appreciated. I've tried researching the net but unable to find any deficiencies that look so uniform.
Thanks in advance!!
