Brown spots on leaves! To Flush or not to Flush? That is the Question.
Hello, Seeing lots of brown spots developing around middle tier leaves. Reddit is telling me I should flush with 15 gallons of water to get rid of salts around the roots. That seems extreme but if that’s the cure I’d like to know more and can I use my tap water (7.1pH 133ppm)?

Feeding
First flowering feed was 0,7ml/L of biobloom and topmax. Second was 1ml/L. This second burnt my wedding cheese. Following the feeding scheldude, I should double the bio bloom next week. What should I do?

Lime Green Growth Tipes
The growth tips on my plants are super lime green compared to the rest of the leaves. Is this a problem? I'm growing in FFOF and I've given very little CalMag and P-T-K so far.

Defficiency or light burn?
I Had this on my previous plants, I'm starting to think it is light related as it seems to happen to the leaves closest to my mars hydro. I wonder what would be the best course of action here? Ive added a tiny dose of calmag, can I supercrop this late into flower?

Top dress ideas during mid flower to help deficiencies after nute lock.
Adding too dress mid flower on a slightly problematic grow that went through possible nute lock 2.5 weeks ago. I am looking for a top dressing mix to add because I dont think these girls are responding well to liquid nutrients so I want to help them out in a natural way.Any tips

Are those nutrient defficiencies? Which ones?
A plant had interveinal chlorosis on new leaves and then proceeded to show brown patches between veins on middle leaves. Another has coppery brown spots on leaf edges on the middle of the plant. Both were rootbound in living soil (peat/perlite/hummus + ammendments).

Possible deficiency?
Am I correct in thinking this is calcium and manganese deficiency? Do I solve this with a little cal-mag? All spots are on new growth so its immobile i think, Cheers people, happy growing and stay green ✌️ 💚 👌

Should I use a pH up -product?
After mixing nutrients with my tap water, the pH of the mix is around 5.5. Should I use a pH -up product? Plant is showing a slight nitrogen deficiency. My tap water base pH is almost 8.0, but the Biobizz nutrients bring it way down. I am using 50% of the recommended dosage.

Raise PH of soil? Is run off actuate reading of soil PH? One of my plants might be getting sick, I need a fix for this ASAP!
So quick question... how would I go about raising PH of my soil. I just took a reading about 5 mins ago from my runoff and it was like 5.8!?! It’s never been 5.8, and I do have a little issue with 3 of my fan leaves on one plant. No soil PH meter. Just flushed them 5 days ago...

Nutrient deficiency??
I am struggling to find out what my plants are lacking or what I am overdoing here, can someone please help diagnose what this brown spots are on leaves? My guess was boron deficiency I’m worried if I don’t fix it quick it will kill the crop :(
