Biscotti Mintz new growth tips/edges white

He leído su diario y no tenemos información de los valores de su ph. Las puntas blancas son por que los niveles de ph están un poquito fuera de lugar. Por el momento no es para preocuparse. Pero mantenga valores de ph en 5.8 y 6 en vegetales y en flora de 6 a 6.5. Suerte

Is this the brand of feed your giving your plants? https://www.seasol.com.au/wp-content/uploads/2017/03/Product-Analysis-Powerfeed-Concentrate-May-2017.pdf It looks like a nice well rounded product but its lacking sometimes. I feel the Mg is a bit low, May want to sprinkle in some Epsom slats once a month just to give it a boost. Also the 12-1.4-8 is an interesting ratio. its a bit low on P for veg. and will not work well for bloom. So you will need to find another option. all the feeds by that company seem to all have high N and low P with moderate to good K. PowerFeed PRO SERIES Plant Food All in One Hydroponic would be a slightly better option for veg but still low in P for my liking. but all the other micros and such are at much higher ratios. https://seasol.com.au/wp-content/uploads/2019/08/Powerfeed-ALL-IN-ONE-Hydroponics-Plant-Food.pdf Your plants should green up in a few days. if not they may need some more Iron and or Sulphur, hard to tell atm. Sulpher and Magnesium is in epslom salts iron can be found in another product like iron 2 sulfate Best Of Luck!

Watch the new growth, as it gets older if it darkens up in a few days, its genetic and you don't need to do anything. If the light green persists then it might be an issue. With regards to the issue it can be many things but seeing as you monitor a lot of stuff I think it might be soil pH. If your soil pH is not adequate the roots might not be absorbing the necessary nutrients to support all the new growth. A simpler cause might be a lack of feed, I don't personally know what your all purpose feed is comprised of but try to do a couple of estimates with regards to NPK to make sure you're feeding enough. Good luck with the rest of your grow and Keep it up cause they look amazing and you're really putting in the work to succeed.
