So this is my first grow 4x4x8 gorilla grow tent 8”AC infinity exhaust fan with carbon filter 4“ AC infinity Intake fan. Using California lightworks 550&275 spectrum led with sunrise and sunset with full spectrum controller 18on and 6off currently 8weeks veg for my Magic Melon Sativa, Early girl hybrid and 6 weeks Orange Diesel hybrid and Golden Graham Indica . All in 5gallon smart pots using FFOF soil using FF Nutrients line up . I was have some nutrients tip burn issues couple weeks ago and couldn’t figure out why bc I was watering once a week till soil drag 1in down . Decided to check run off ppm and saw 2500-3000ppm I freaked out and immediately flushed my medium down to 900 ph6.2 i is RO water the next week the color came back they my magic melon clone started to yellow on the new growth I thought sulfur or iron deficiency but i seen in MR Grows youtube video talking about ffof soil and organic that flushing isn’t necessarily so should I have not flushed or do they look good or do I need to feed more

You're right when you say flushing in your case wasn't necessary. Thanks for posting some pics in white lighting; the purple lighting pics are kind of useless since we can't see the color of the leaves. Overall your plants look good!
