Man, i had a plant die on me on 5th week of flower, and that’s sounds so much like i did to her…
Im checking runoff for the first time at 7th week of flower and im absolutely alarmed, even though they look good to me…
I did a flush with 7.2 ph water going in that started with a runoff of about 5.1 ph and later was a bit up at 5.3 ph…
I’m in a mix of about 60% coco, worm castings and cheap soil, that drains reasonably well.
The plant that died did it while looking great until she collapsed completely in a matter of 2 or 3 days…
I never really watered my plants to runoff, and probably it had salt buildup and a very low ph…
I am going to let them dry up from this flush and then do every water to runoff, once a week, instead of 3 small waterings a week.
Sadly i still haven’t got a ppm meter yet,so no idea…
This thread was very ivnformative/worrying for me
How did that grow ended up?
@DMD I grow in coco as well in 7 gallon pots. About every 3 days my pot needs water. I will run 3-4 gallon of plain ph water through to flush the salts and built up nutrients out. Then I make nutrient water and run that through. As @Familyman said, feed everytime, I get great results like this
That grow wound up producing very well. The Chocolope yielded a pound, the other three were between 11-13 oz each. Without my screw up, maybe I could have done better? The grow I have going on now has been smooth so far, water feed with Florakleen once a week, feed every day. I’m 4 days since flipping to 12-12, and all is well!
im currently on week 4 flower and my flowers are being held back i feel, i run my ppms at about 1200 with a dtw method feeding constantly every 4 hours i raised my input oh a bit for flower to about 6.2, im starting to get run off of about 1450 ppms and a ph of 5.8 tho, that means i need to lower my input nutes right?
Hey can you help me with this? I never ever checked my ppm until yesterday and I’m embarrassed to say the runoff in my coco was over 3000 and i couldn’t believe my eyes… this is my first time ever growing and i have several gdp from ilgm and they do come out beautiful but I’ve harvested 6 so far and only 2 tasted bareable the other 4 horrible like home grown regulars or something anyways i seen you mention the best taste for pot is around what ppms now? Please 
break it down for me because i have everything down packed except for the frigging taste…please help! Plants look great but taste like 
A lot has to do with the drying and curing process also. Just saying that has a lot to do with it also.
I’ve done some reading on your post and even though you are using A&B in coco you still have to use cal mag coco it holds on to it so you have to increase the normal amount that would be in the canna.
Even when you do just water if using RO u need to add enough cal mag to ph it
