answered grow question 6y ago
If they came off towards the bottom of the plant, it is a nitrogen deficiency. If not, since the yellowing and necrosis begins on the outward edges, I would say it looks like a Magnesium deficiency.

Day 38 autos: is this nitrogen deficiency or something cal mag could help with?
Kia ora whanau, Each of my three flowering autos (the Herbies Beginner Auto Mix #1: Ape Fruit Auto, Purple Chill Auto and Godzilla Cookies Auto) has an issue with yellowing older leaves. Do I need more nitrogen or is this potentially something cal mag would address? TYVMIA!

Unfortunately, 2 ladies have had yellow tips on the new shoots the whole time. The 3rd one looks good. Fertilization is done according to the Athena chart (40%), 3.0 Ec was too high for me. The last hand watering was with Ec 1.7 pH 6.3. Drain was at Ec 1.4 pH 6.2. They've been in the AutoPot with AirDome for 3 days now.

Both of my Strawberry Shortcakes began to yellow. At first, I though this was a nitro deficiency and applied nutes to combat, but color is changing unevenly. Autoflower week 8, 62-82f, 72-42rh, water in 6.2-7, runoff 6.5-6.6 300-500ppm, double dr earth 4-6-3, ff half dose

Look like Zinc and Calcium deficiency? Watering with 5.8/5.9pH, 2.06 EC (Runoff 5.8pH, 0.78 EC) Few leaves had small nutrient burn on the tips earlier this week. Nutrient burn appears to have tapered off.

Let it grow or cut it out?
One of the seedlings isn't doing so hot. Should I just start a new seedling in it's place or give it more time? I've had a stunted seedling like this before in a previous grow and it ended up yielding a lot...

Yellowing to slight grey leaves
What's the cause of the older yellowing leaves with some grey and the slow spread to the newer growth? I'm between pH problems and or deficiency but not too sure.

What deficiency is this?
What's my plant missing? Growth has slowed down, and I think I'm seeing veinal chlorosis, see last picture in week 2 / or attached pic. I've been feeding A + B with a tiny bit of cal+mag at an EC of 0.8, now reduced to 0.6, pH around 6.

Yellow spot on my leaf. :) PH fluctuation ?
(Water change) I had set to 5.5 PH and waited 20 minutes. I put in my fertilizers, everything was fine. The next morning the ph had dropped to 4.7.. So I put it back up. The next morning yellow spots appeared on the leaves. Did you confirm that is due to ph fluctuation ? Thank's
