Dialing In MEGA CROP for Auto's

[Waira]

This.
I'm using RO water so that's 4-500 ppm of MC ,that's it?

I believe so mate,... MC is more tricky than usual for this, because there are so many things in there beyond the primary, secondary and micronutes... Si, amino's, sugars, etc.,... the hitch is some of them are not ions (carry not +/- charge), like the amino's and sugars and as such do not really register on EC/TDS, but can still affect osmotic gradients which is how, very basically, stuff gets taken in.... So this is something to keep in mind while tinkering with dosage!

@pop22 @Dabber -- your ppm's, that's all MC ppm, not including any water base, right? - just to be clear for other folks!

ppms I just weigh mix feed dont even ph anymore

Thanks. Ive gone upward of 1000ppm and pretty sure it was too much. Had some burning tips. but most leaves on the 3 plants are still yellow but producing some decent buds, that's why I kicked up the ppm. have had ph mostly at 5.8. recently have gone to 6.0

My first grow I used Biobizz lightmix with advanced nutrients and cal mag and by week 5 3 of the 4 plants had sooo many yellow leaves
I still was able to get 6 ozs of pretty decent buds but it was not ideal.

This grow I went with Promix hd and used only mega crop, molasses, and calmag. By week 4 was having some pretty bad yellowing. They are getting close to harvest so it is what it is...just frustrating. I guess that's how you learn lol

Next Grow I was thinking megacrop, bud explosion and sweet candy but still worried lol

I found this schedule, how does it look to you?View attachment 1164054

I never go over 4 grams per gallon, dont weigh BE or SC and havent used cal mag since 3rd grow

lotta help you are!

when I first started using MC I was told to weigh it and it has worked that way for me so far, you've seen my grows Hell the EC/PPM meter I have has never been took out of its case

So you never go over 4grams per gallon, that's with MC, BE and SC combined? 4 grams total... just to be clear lol sorry

This is what I have been dealing with...so ungly

my 5 gallon flower mix 20 grams MC, 1 tsp SC, and 1/2 tsp BE. Here's a look at the Double Grape I just hung, the one still have to chop and 24C x CQ still going fed the my mix

When I was phing MC mix I always ph to 6.5 then now I dont ph

Nice man looks good! Thanks for the info.

Stay on the low end for soil, higher with coco or other soiless mediums. DWC etc can go to 650. As always watch your plants to see if its too much or not. Any plant with medium green leafs and no clawing is getting enough. Most people way over feed!
