@@@themilkman, I agree and did pretty much exactly that today to see how it goes. Fed her 550ppm with GHF Hybrids base nutrients and the same a couple of days ago at feeding time. Added 1ml of Magnesium sulphate per litre of water as I read it’s hard to over do it with magnesium. It’s hard to say for sure but I think that the variegation in the newer leaves is not looking as bad today and growth is still quite quick, just very tight node spacing which I think is genetic.

@Jungian79, The GHF hybrid nutrients seem like they would be pretty complete on their own especially with tap water. If this was my grow I would ditch all the extras and just go with the base powder to about 500 ppm pH it and call it a day. My opinion is that you will have healthier plants and save yourself some cash. I have purchased more nutrients and additives than I care to admit and ultimately I have ended up with a 1 part nutrient, Cal Mag (only because I use RO water), Epsom Salt at 1.25 g/gallon and some pH up. That is all. I add the Epsom salt only because I get a very slight magnesium deficiency that shows up week 3ish of veg, which makes sense. I only feed at around 400ppm in Veg and that seems to grow them well without wasting a boatload of nutrients. The 700ppm and up is best left for flowering. IMO.

@@@themilkman, Hi, yes I’m coming around to that theory too. I read somewhere that too much calcium can cause lock out issues and as I’m using tap water in a hard water area it’s worth not adding too much cal if it’s not needed.

@@themilkman, Cheers for the help. 👍
