What is your growing medium? If you’re growing in soil I highly doubt it’s a cal/mag issue as there is plenty of cal/mag for a grow in most quality soils, more likely you’re Experiencing pH fluctuations in your medium.

Vague, though I would probably use calmag...but then, I'd probably also add a bit of sulphur and phosphorus if I have some.

1.0 ml of calmag per 1lt will do it wonders for next week or 2. Then start lowering it 👍🏻🌱❤️🍁

Why isn't it going away?
It might be a potassium deficiency and I believe it was so as i was running out of nutrients and i had to lower the nutrient dose i was giving by hand. On the 22nd, i added the nutrients to my AutoPot reservoir so that i no longer had to hand water them and it still has this. SOS

PH Fluctuation Early Signs?
I am worried that I either have early signs of PH fluctuations outside of 6.0-7.0 range or early signs of a calcium deficiency. As you can hopefully see in the picture the tips of the first set of true leave seem to have little spots of discolouration. Any help is appreciated😊

Some kind of deficiency?
World of Seeds Strawberry Blue. Pretty slow, uneventful life this far (on me). What seems to be wrong? Veg and a lot of light. FoxFarm soil. Half to full strength of the General Organics line. Bottom main fan leaves going first. Please refer to pictures. TY for any input!

How much water for 4 week old plants in 3 gallon pot - 24” from light?
My question may be the most basic of all. This is my absolute 1st time growing and am wondering how much water I should be giving my 4 week old plants on any given feeding? They are under a 150 watt led light - 24” from plant.

Yellowing a bit too soon
During the second week, leaves started to look a little bit yellow. The first true leaves yellowed way too soon. I'm guessing lack of nutrients. It never showed signs of drought or overwater stress. Your thoughts? I planted it into larger 2.5 liter container now.

Too little calcium in early flower?
I’m in the early weeks of flower and am seeing this happening. I thought it was due to an attempt at foliar feeding, but those initial problem leaves have been trimmed. Is this a calcium deficiency, and if so, how can I address it? (NLS top dress/coconut powder/recharge)
