Anybody else using 5g of maxi show some deficiencies in coco, and switch up to the 7g formula with any success? Any reason why the original post still refers to 5g/gal, and so many people appear to be still using that formula, when 7g does appear to calculate much more accurately to the supposed Lucas ratios? Kinda confusing.
Absolutely!aight so lucas formula can be used here without using RO am I right?
thanks for info btw
Yes and you want pH to be 6.3-6.8 for soil.
I think it is going to depend on the strain but I have only used the 6/9 ratio. You could do half the plants at 6/9 and half at 8/16 and see which one works best for you. How are your temps and airflow? Those plants look a little heat stressed to me.
ok running the k.i.s.s method with tap water and maxibloom. the maxi drops my tap water down to 4.8 PH. i have to add like an ounce of ph up to get it back to the 5.8 to 6.0 range. is this gonna have adverse affect on my plants? i have tried using silica blast as ph up but still needs a shit load to bring my ph in range. any suggestions? btw im using str8 canna coco
Okay ill stick with the 6/9 ratio at ph 6.5 then. My temps stay in the 67-76 range and i have my fan that aircools the light set on a thermostat thats set for the day temp to be around 75. I just recently put some other fans in the room to move some more air around. Im hoping after this feeding i gave them it will perk them back up. Do u think its bad that my drip system doesnt water the whole container and only drips down in one spot that spreads a little bit around the pot.
What kind of PH up are you using, and how much water are you using? It's not all that unusual for my unbalanced nute mixture to end up with a PH in the high 4s, and it does seem odd that you should have to use that much solution to adjust the PH back into range....unless you're mixing up a 5+ gallon batch, in which case an ounce of PH up might not be all that excessive.
i'm using the same things as you .... maxi & silica blast (i use the dosage on the bottle ... no more ) as ph up mine gets to 5.6 with that mix so i add earth juice ph up to bring it to 6.2 for me . EJ ph up is just potassium bi-carbonate . comes in crystals form ...easy to mix . i'm also worried about using the chemical ph ups on my plants . was using a shitton of GH brand ph up to get it into range so i started looking around for different things to use . I'm using RO water & when i add my calmag (every other feed ) i don't even have to use the EJ stuff to bring it up .ok running the k.i.s.s method with tap water and maxibloom. the maxi drops my tap water down to 4.8 PH. i have to add like an ounce of ph up to get it back to the 5.8 to 6.0 range. is this gonna have adverse affect on my plants? i have tried using silica blast as ph up but still needs a shit load to bring my ph in range. any suggestions? btw im using str8 canna coco
can i use the lucas formula with fox farms soil like ocean forest and happyfrog amended with perlite? and if so what ph do i water with.
