This is my first grow so just looking for some insight. Dwc grow 600w floraflex at 30% ph stays around 5.8-6.0, ppm is about 650-700(not sure if thats high), using 3 part an nutes, silica blast, calmag, liquid kelp, rapid start and hydroguard. I started noticing very faint yellow patches in between veins on leaves and its progressed with the very tips on the serrated leaves yellowing and seeing more yellow in between veins. Still early stages so wanting to fix it before it becomes a problem. If any more information is needed just let me know. Thanks for any insight!

This should be on the sub cannabiscultivation
Add CalMag for sure
Yeah it said it would discard if i continued im rather new to reddit so not sure how it all works
Don’t just add CalMag. Anyone telling you that has no idea what they’re doing. Although the symptoms displaying could be a Mg deficiency, it doean’t mean you need to add more.
First, I would make sure I’m using the correct micro component to your three-part base fertiliser. Match it based on your municipal water type.
Always use EC over PPM 🙂 PPM has there are two measurement scales, 500 and 700. Thst being said, 600-700 is actually on the low side.
Personally, I think you just need to increase the feed a little. The kelp will be hiding other issues.
PS: Theres another sub for Cannabis related questions.
it looks good what strength nutes are you doing
the only thing i can see is a grower overthinking. your plants are fine
Let it grow and stop hovering over her 😊 she looks good 👍🏼
