    Default Answered: Wtf Is That? Brown/rusty Patches

    Hi,

    I've been a soil grower and this is my first time trying Hydro.

    - Im using a 9L DIY DWC Bucket
    - Strain: CBD Crack(Fastbuds)
    - RO Water with 200ppm AN Sensi CalMag (4-0-0) 3.2%Ca 1.1%Mg
    - Maxibloom Lucas Formula my solution is 900ppm(including calmag)
    - checking pH twice a day not much to adjust is always between 5.7-6.0

    I top off and changed the water once after flowering

    I had a small spider mite problem trimmed all the affected leaves and it seems to be under control. The roots are looking fine no brown/ish tips.

    From the look of it I would say calcium deficiency but Maxibloom+Calmag must be enough so it has to be a lock out but im not sure...would appreciate some advice.

    Thanks!

    I’d say it looks like it could be ph fluctuation mate, havr you collaborated your meter maybe?
    Also I don’t really think I’d use RO water personally mate I’d just use tap water.
    Peace

    I have a Apera ph20 which I calibrate before every grow and it did good job the last few grows so I can be pretty sure its not pH related. My Tap water is not ideal 10:1 ca:mg ratio thats why i used calmag.
