Does that look like an early deficiency?
Hi everyone, what ya thinkin' What kind of deficiency could that be? My bet - potassium. last portion of water was ~6.2 pH I wasn't feeding her nutes for ten days by now. Because previous runoff was ~2000 ppm. I thought would be a good idea to do just water for a while.

First grow yellowing seedlings :( nute problem?
I seem to be following all the instructions on grow temperature range, light distance, and watering schedule(only watering hen the medium is drying); I've hardly used any nutes until day 22 as advised and I personally think this has caused me some issues although I may be wrong.

From the start I’ve been watering with ph 6.5. I just discovered my runoff is 7.1 and I have what I believe to be a zinc deficiency. Similar issue on my previous grow. How can I fix my watering routine such that the ph stays more stable?

Yellow spots between veins
In several weeks my plant has yellow spots between veins, but it starts from the top to the bottom of the plant: old leaves seems fine when the new ones are spotted.I thought it is Mg deficiency, fed my plant foliar with epsom salt, added CalMag to the feeding, but no luck. WTF?

A few of the leaves started to get yellow spots along the veins. I was pretty sure it was nitrogen deficiency so I upped the nutes a little. Over the next day or so, 2-3 different leaves started to curl down at the tip. Is this too much nitrogen?

Help the rookie w/ a possible calmag deficiency?
Does this look like a calmag deficiency? Link to my journal entry for settings/water param/etc for these to see if you can spot the issue? https://growdiaries.com/diaries/187101-grow-journal-by-mrlahey. Using TDS 0-2 ppm ro/di water with calmag additive.

K deficiency or nute burn? And some small holes in leaves.
looking for some advice for 2 things. I've been doing a lot of reading & am wondering if this may be k deficiency instead of nute burn as i originally thought. The leaves are browning all along the edges, & some yellowing on the leaf. Second, seeing a few holes in some leaves

Strange coloured fan leaves (3) on one of my 4 plants, maybe some sort of deficiency? Thanks people!
Hey there smart people! I have about 3 strange coloured fan leaves on one of my 4 plants and I’m not really sure what to make of it. To me it doesn’t look like any deficiencies that I came across per say. All other leaves look nice and healthy. Kinda randomly scattered. THX!

Nutrient deficiency, pest or under-watering?
I'm not sure whether i'm having a nutrient deficiency problem, am under-watering or having a pest. As you can see some leaves dried up and turned yellow and i'm also noticing a little bit of interveinal chlorosis.
