GH Micro+Bloom vs Micro+Bloom+Grow and pH!
    #445962 - 07/13/10 05:37 PM (6 years, 4 months ago)

Hello folks,

I'm looking to hear about everyone's experiences with the GH 3 part lineup. I've read into mixing the Micro and Bloom at various rates (8-14,6-9,8-16, and 7.5-16) known as the Lucas or modified Lucas formula. The original Lucas formula is 7.5-16 or 8-16 for simplicity.

I've been told using all 3 parts is cheaper and better for veg and early flowering.

Reasons:
GH grow contains  2 % N where Bloom contains none
GH Grow is cheaper than Micro (as is Bloom)
GH Grow contains 6% K and .5% Mg which is more appropriate for vegging (Micro contains 1% K and no Mg, Bloom contains 1.5% Mg and 4% K)

Reading into the Lucas threads specifically the Head and Rezdog as they're modified for coco which is my choice medium (at the moment) Head recommends a pH of 5.8 or 5.9 is appropriate and Rezdog originally recommended a pH of 6.0 and then later recommends a pH of 5.5 what is it? I have friends who grow in hydro and say the correct pH is 6.2 as Mg is locked out at a pH lower than 5.9. Looking at various charts it seems 6.2 could be correct for "hydro" and 5.5 could be correct for coco as "soilless" seems to be optimal at that range. This doesn't explain why promix users generally use a pH of 6.2 or so.

What is the verdict? You decide!

I grow using a pH of 2.3 in soil :shrug:

And no I'm not fucking with you

I heard from certain commercial green houses that they will do non-nutrient watering with a water PH of 4.5-4.8 to help prevent any type of root rot.  But 2.3 is pretty hardcore. 

Is there any reasoning behind this, or is it something that just always worked for you?  Also, does this even include when you're watering with nutes?

your soil has a pH of 2.3 or your nutrient solution does?

do you intentionally use such a low pH?

you grow cannabis in this soil?

This article is rather interesting on the subject of nutrient ratios.

http://www.maximumyield.com/article_sh_db.php?articleID=464&submit=Go

The highlight of the article:

Three part base nutrient systems have been widely used and accepted through the indoor gardening community, and have been delivering great results for years. Based on modern research conducted on indoor grown high yielding crops, it was determined that using the three part nutrient system actually produced better results when being applied in a 1:1:1 ratio versus the common 3:2:1 ratio, especially when bloom boosters intended for indoor crops were used in conjunction with the three part nutrient system. 2:1 ratios of three part base nutrients were the least effective of all (where the “grow” component was omitted entirely through the bloom phase).

Upon analyzing the nutrient levels and ratios achieved in the nutrient solution for feeding indoor crops in the bloom phase, applying the base nutrients in a 1:1:1 ratio using popular three part nutrient components, the level and ratios much more closely resembled those of the internal nutrient levels and ratios of the plant being grown versus using the three part nutrient components in the common 3:2:1 method.
