I've been pH adjusting my "ladies" since 12/26/16 to
[email protected] during my whole GROW. During this time I've experienced yellowing between the veins of my new growth along with some older leaves. During the past weeks I've had this issue although the plants were developing new growth. I've tried to, in minimal portions, add nutrients after seeing that my PPMs were low or adjusting pH back to
[email protected]. Now, I've been doing this faithfully and haven't seen any results much. My notes do show that when my pH was accidentally dropped a few times below 5.8 at exactly
[email protected] I saw what I believed the next day to be "improvement". However, that was "short-lived" the following next 2 days according to my notes when my pH was adjusted back to
[email protected]. The leaves, again, began to yellow along the new growth and old leaves. This past week I've been analyzing my PRECISE "notes" I've saw a pattern where leaves would improve during times my pH was "OFF". I began to run test on some,3.5 weeks EXACT since Germination, plants of the same strain. I pH adjusted 2 plants at a routine rate of
[email protected] with a fluctuation ranging max
@6.5 during all 3.5 weeks my leaves were yellowing. I pH adjusted 2 other at the same routine rate of
[email protected] with a fluctuation ranging max
[email protected] NO yellowing appears what so ever. Both plants were tested using NO nutrients.
What I found is that at a range of
[email protected] the plant does not receive enough "manganese". My test have concluded that at
[email protected] the plants new growth has extreme yellow along with old growth. My test showed that
[email protected] displays no yellowing on any parts of the leaves.
Function: Manganese is used in plants as a major contributor to various biological systems including photosynthesis, respiration, and nitrogen assimilation. Manganese is also involved in pollen germination, pollen tube growth, root cell elongation and resistance to root pathogens. SOURCE (

I'm not sure if I'm CORRECT, though my test show I could be. To keep your
[email protected] during your whole growth can induce toxicity in the plant as manganese is needed only in very small portions and is easily consumed at pH&5.5. I recommend starting the week at
[email protected] and continuously lowering pH if needed to no LOWER than
[email protected] as most important nutrients such as Calcium and Mangnesium aren't consumed anywhere below
[email protected]*.
That is what I have discovered during my past 3.5 weeks of Germination for the SWEET TOOTH KUSH. Please EXPRESS yourself freely even if it is harsh. I am not offended as this was a test that solely proved plants needed a
[email protected] during the start of my week. I could be wrong. I just don't see how if my test showed otherwise. Unfortunately, I didn't take photographs. I will my next test pH test @2/28/17
. But yea thanks for attempting to ridicule me and obviously challenge my integrity.... 
haha lmao
