Im just about to start my second week of ripe solution, and all my plants are looking great. but they all have lower leaves with some yellowing and burnt tips.

Im running them at a pH of 6.25 and ppm 1050 Bloom/Ripe Solution.

I'll post a few pics and if you have ideas please let me know if theres anything i can do. also check out my journal to see my whole grow...

this is my first major grow, and from what i have read 6.2 is about right for flower. I could be wrong tho, most my info comes from forums like this and a couple beginners books. you think i should lower to about 5.8-5.9 and see if it helps? im so close to harvest im not sure if it would be worth it now. I will start flushing in just under a week. let me know what you think, any feedback helps!

6.2 is on the high side for hydro! Yes I would even water with say 5.4 so the runoff hopefully comes out closer to 5.8. I not going to read your whole grow you should of included your method of hydro here. I'm growing in all rock wool right now and I know you should keep your ph below 6.0 I shoot for 5.8. And I'll water 5.0 if that what it takes for the runoff ph to come out at 5.8! I'm thinking this don't matter earlier in the plants life it slowly deteriorates the roots! That's why it a issues later in its life~

Trace element lockout. Get the ph to 5.8 to correct this.
