Help in understanding instrument readings for hydro

just want to say, those answers weren't visible when i answered (but clearly they were long before me)... if i stepped on any toes.

ppm of 1500 might be 'slightly' high? but, looks beautiful, so i wouldn't go rocking the boat. it's all a balance.. perfect pH requires a certain balance (within common sense reason) otherwise.. it is all relative.. you seem to have found a good happy medium. leaves are praying, no burnt tips, color seems consistent all over (diffiuclt in to see in best pictures, RL is better to assess such a thing). MAybe, dial ppm back a tad.. 10-20%? Someone with more hydro exp will have to chime in for that. EC of 2 is fine for a mature plant (that's ~1000ppm with US standards, and will vary with a different EC pen not american-standard. may not be called "american" lole, there are jus two ways it can be measured based on the meter you buy.) micorsiemens - uS of 3200, so you are "US standards or Hanna etc.. 500uS/cm = 1EC, so EC/2 = ppm in this case https://en.wikipedia.org/wiki/Siemens_(unit)

Hello.. Hope you are well.. In hydro the main things to consider in ur res is ec/ppm and Ph.. Ur ec/ppm is an indicator of the amount of food present in ur tank ec stands for electrical conductivity and ppm stands for parts per million.. During the flowering stage i personally start at 900ppm and raise it by 100ppm each wk during an 8wk flowering phase, ending at 1400 at end of wk 6 then give half feed (700ppm) for a wk then plain ph'd water on final wk for flushing.. Ur correct by saying ur ph is bang on, this shud b 5.5-6 in active hydroponics.. _s/cm(no symbol on my phone 😂🔣) id the measurement of micromoles ur lights are putting out.. Anything over 1000 in flowering is considered gud.. So ur smashing that👍.. Humidity during flowering i personally like to keep under 50%(anything over this can introduce moulding) at all times and drop to 20/30% if possible during last 2wks.. So ur all gud on that front aswell.. 👍 Temps ideally shud range between 21-26 but that totally depends on strains and how much air ur room exchanges each hour..wer all struggling (indoors) with heat atm to be honest.. Hope this clears up a few things for u.. Please choose sum1 else who answers this as i wud like whoever is in this months gotm comp to have the selected answer.. Stay safe n gud luck with her.. 👍🍀
