I'm using the 2-part and I have been following
@Mañ'O'Green's schedule that I believe he had created for you
@NorthernLights_420
I'm in a 4x4 tent with 3 gals. of Coco/Perlite at 60/40 in SmartPots using AutopotsXL. Mephisto Mango Smile and Strawberry Nuggets. I've been adding 1mL/g of CalMag+ as I'm using bottled RO water. I have a Bluelab Guardian on my res so I have been really good at keeping my pH in check and my PPM no higher than 620. The leaves started out really nice until about week 3 when I started seeing yellow veins. Looked like a Magnesium deficiency.
@Mañ'O'Green to note: the NPK RAW B-vitamin only has 9% Magnesium...not 99% which is on your feed schedule. So, I added in 1gr/gal of Epsom salt which seemed to help.
Unfortunately, this is where my grow is thrown off. I was under an SF4000 that started acting funny last week (mid-flower). Dimmer went haywire so I swapped that out with a MH SP3000 from my 2x4 tent. Sucks that I had to change lights mid-flower and I think that may have something to do with the light stress I now have. Up top, the majority of the leaf tips are now burnt and curled up....but I'm slightly thrown off as the leafs up top are also praying to the light which is 24" away and only showing 42k lux at canopy level.
Also to note, I had purchased SC and BE but noticed that over on Amazon a GL rep states that you do not need to add the GL supplements to the 2-part. So, I reached out to them to ask and got 'it's optional". So, of course, I just haaad to add in some BE in which can also be a reason for the shape the leaves are in now (looks like Potassium).
I have a lifetime supply of MC 2-part as I bought the 25 lbs. bags. Needless to say, I will be working on 'perfecting' MC 2-part on my future grows. The NPK RAW supplements are a fantastic product as well.
PS - take this for what it's worth as this is only my 2nd grow and coco/Autopots are new to me. My first grow I went balls to the wall with 4 plants in DWC buckets that quickly grew out of control, hence the switch to easy peasy Autopots thanks to
