I had placed the autoflower GSC extreme from ilgm, on March 1st. I’ve noticed my leaves are getting brown/ rust looking spots. I top feed my plants with some bud booster bat guano, worm castings, I use cal mag and molasses, aswell as epsom salt. I did this for all my plants and this is the only one showing a deficiency. Is it too little cal mag or is it something else ? I water anywhere from 6.5-6.8. The run off of this plant was 6.3 today and everyday the brown spots keep appearing even after removing previous damaged leafs. The lower leafs are slightly fading and dying but the flowering process isn’t done, still has tons of white hairs. Any help is appreciated! ![image](https://global.discourse-cdn.com/growingmarijuana/original/4X/5/8/2/582e13faf5153ef73aba1cf3e1dadd2439fbe43e.jpeg) ![image](https://global.discourse-cdn.com/growingmarijuana/original/4X/7/b/6/7b6d1d758e9aabe64ceae0294d78cd9d1895c904.jpeg) ![image](https://global.discourse-cdn.com/growingmarijuana/original/4X/9/9/f/99f3b2d61ab8140a1186566113c3162c93adc113.jpeg) ---

Coco w/ perlite should be fed at PH of 5.8 target range. If you don’t have a ppm meter, how do you know how much you are feeding? You’ve got to have a working meter. Correct the PH and get a ppm meter and you may see how far off you are. Good luck! 👍🏻✌🕶 ---

5.8ph why 5.8 ? ---

I do have a ppm meter but it’s somewhat broken it doesn’t give the exact amount but close to it, I calibrated it as close as I could until the new one comes in but I also heard growing organic with amending soils you don’t have to worry about the ppm as your feeding the soil and not the plants. That way the plant can uptake it when ever they need. I’ve done this same method for my other 3 plants and they are healthy ---

Coco is in the hydro family so you have to PH it at 5.8. ---

So I just fed about a week ago with some beastie bloomz, bat guano, worm castings, molasses, cal mag, with a ph at 6.7, run off is currently 6.2-6.3ph and with my current defective ppm reader I’m getting about 1200 ppm in the run off aswell ---

I assume this is now advanced calcium deficiency from what I’ve found but how do I go about fixing it? ---

> [@BigCat420](#): > > I assume this is now advanced calcium deficiency from what I’ve found but how do I go about fixing it? Calcium, probably some PK deficiencies in there too. Just keep feeding them everything you can, this will get worse before it gets better being this close to the end. @BigCat420 ---

Thanks man. I did up the cal mag a tiny bit and back off the molasses in this new batch of water but I guess I’ll keep feeding them and watch for any new signs. Anything particular to watch put for moving forward like signs of progression on calcium deficiency? ---

> [@BigCat420](#): > > signs of progression on calcium deficiency? You will see this getting worse, because you’re seeing a deficiency you’re trying to keep up. It’s so late into flowering all you can do is keep up, until you’re close to chop.
