Low pH
Organomananswered grow question 4y ago
Not a pH problem, but the beginning of a cal/mag deficiency.
Easily resolved by feeding with a calcium/magnesium booster fertilizer every week or two.

buy a 100pk of strips that resolve down to .5pH ... the ones broken down into 4 colors are easy to distinguish.
this will 2-3+ years worth of spot checking for 5 USD. Probably cheaper than the meters and stock solutions to keep one callibrated... and you have to buy a new diode every few years anyway. strips are easier and cheaper in most contexts, unless you plan to use it every day (i.e. very frequently). .5 resolution is enough for gardening needs.

Brown leaves - what am I doing wrong, folks?They look yellow in the photo, under 250W of blue light, but they are brown.
This starts at the tips of the large lower leaves and spreads quickly to the whole leaf.
Also modest edge curl.
What am I doing wrong here, folks?

Having an issue where the leaves are spotting Brown. I’m adding cal-mag and am not having this issue on any other plants except for this one. I thought it could be from misting the air with a spray but stopped that for a while and it is still continuing.Week 3

What's wrong?!Can anyone tell me what's going on with this? Leaves are getting white markings and are fairly limp to the touch (although they are not drooping). I've checked underneath and there are no signs of any bugs... nothing flying through the air... All other plants are ok!

Is this a symptom of spider mites or something else?Is this symptom caused by spider mites also, or is this a different issue? There is pale green/loss of color along the veins of two leaves. I’m aware of my spider mite problem, but want to know if there is another issue or just more symptoms of the mites.

On my NLxBB there appears to be rust spots developing on both sets of the first true leaves, i've only fed nutrients once on Day 10 and that was at quarter strength.
Not sure if this is a sign of overwatering or if I need to start feeding with Cal-Mag more regularly.Week 2
