I happen to LOVE my Apera - it's a bit cheaper than Blue Lab - but just as accurate, just as easy, and, from others who have switch to Apera from Blue Lab, apparently longer lasting. I picked mine up from Amazon for about and it's the BEST I'VE EVER SPENT ON MY GROWS!!! Wish I had bought one when I first started growing...
As for your yellowing new growth, your instincts are spot-on... this is some micronutrient deficiency - zinc? Iron? who knows... but the key and the answer is going to be found in the PH level ... so once you get your PH pen, make sure whatever you give her (water, nutes) has a PH of 6.2 - 6.5 and you should see improvement....
Good luck!

Blue lab, it isn't cheap but its worth it and will last a long time. I bought mine January 2021

I use a piece of toilet paper, wick up some runoff and then adjust my next watering if its out. Best thing to do is mix in powder wollastanite, dolomite lime, or something in your substrate that will buffer your root zone. Any fluctuations out of zone are likely caused by acidic, non beneficial, microbial life and it just needs a substance that is constantly neutralizing. At least thats what i have found.

Just buy a decent one first off, buy a cheap one and you will eventually end up buying the decent one anyhow......
Buy once, cry once!
Save up until you can afford the real deal, Blue Lab seems popular.

Really this can be solved HM brand or hanna are great and accurate for this job. those from China are not waterproof and need to be calibrated frequently, which would require a lot of work.

FormaHello. I have a question. If there is a risk of nitrogen deficiency on the leaves, it looks like something is missing. pH 6-6.5 on the leaves you can see slight discoloration.

Ec rising in hydro (6th week flowering - closed circuit tank and drip)At the end of every day, EC rises by 0.2 at least. Starts at 1.60 and then in their evening it goes up to 1.83 ! So I have to add water (2L) in order to go down. Does it have to do with the fact they had overfeeding, toxicities and deficiency so they don't feed well ?

pH is 5.5 but i have nutrients deficiency. Can it be the cold?One of my plants (in soil) has yellow leaves and brown spots, it is possible that it lacks Ca and Mg, but it's pH is 5.5. I wonder if this nutrient deficiency is caused by cold water (now I'm using it warm and waiting), low temperature or high humidity.
