According to your log your pH is a bit high.. this can cause a lockout of iron which it looks like what its doing.. shoot between 6.0 and 6.5 if possible! Cheers and happy growing!

Hey Guys, my NL is starting to have some issues. I started off with the leaves just laying low, i've eliminated lack and excess water, and it's not temperature related. I did a small flush 3 days ago and things got worse. What do you guys think?

Hi, I noticed some issues on the upper fan leaves of my Vertigo Autoflower (week 10). It is my first grow and I don't know what to do. buds look good, dense and big - at least for the Marshydro TS1000. I used Biobizz grow, bloom and top max. I planed to start flushing next week.

Yellowing...Deficiency or leaf septoria?
The leaves on the plant are beginning to go light green. Then I noticed this leaf with an unusual spots on it. I’ve been responsible with the nutrients. Hopefully this leaf isn’t suffering. I’ve moved the lights up a few inches to be safe.

Is this normal new leaf color growth?
It seems again that my leaves are a touch shiny, slightly curled down, and are a touch yellow. I water only 1 Liter every two days and do not use any fertilizer apart from coffee grounds and aquarium water which has slight minerals. Thanks for the help in advance

Leaf problem and purple stems
Hi, I have a problem with my auto. I have purple stems and problems with the leaves. The soil contains organic nutrients and mycos sometimes I add flowering boost from royalqueenseeds so I don't think it is P or K problem. Is it a nitrogen deficiency ? Thank you for the answer
