Seedlings going yellow
grimlymanstarted grow question 4 years ago
Could yellowing of leaves on seedlings be from too much fertilizer ( liquid fish, compost,seaweed type.)
I wouldn't suspect iron deficiency as it is new premium potting mix that they are planted in.
I did feed with about half strength liquid feet about 5 days ago.

Yes I would say it's a little bit of iron defiency . I add calmag plus which contains iron as I used to have this problem but it's stopped now .
Also what leaf blower said was true . You may already have iron in your soil but if it's not at the correct PH the plant won't absorb it. So checking PH is the first thing you should do . If that's fine maybe add a little more calmag plus if it contains iron .

Almost every problem can be tied to ph. Every time that happens in my hydro setup, ph is running higher than it should be. I would start with putting the PH pen in the dirt and check it at different spots.

2 autos with crispy feeling sad looking leaves, how can I help them? (more info in diary pl & crit)2 of my autos have been growing leaves that feel crispy and look deformed. I have been watering when the top 5 cm of the soil dries, but I fear maybe I fed them too much nutrients. The temp has also been on the high side (30C 80F). What could be wrong and what can I do for them?

Leaf IssuesHey all, my almost 5 week old Moby dick auto flower is starting to show some issues in the first week of flower. She got a dose of Veggie nutes 5 days ago, and a little bit of Bloom yesterday trying to fix it. Temps have been high and humidity low, would that cause this?

Leggy Seedling Recovery attemptPlant got leggy. Lowered 100watt vivosun grow system light. DLI is now at 40 with 20hr on cycles. Plant dropped into final pot so soil could support weak thin stem. Watered recently and leaves got more yellow. On day 4 after recovery attempt. Any advice? PH 6.2-6.5.

Lower leaves too pale or yellowing?I am noticing the lower leaves of my Royal Critical Automatic to be much more pale green than the top of the plant.
Is this a nutrient/light/watering/lst stress problem if at all?

Yellow on leavesDay 13 leaves started to look yellow / dull on tips hasn't seemed to improve 2 days later, it is the auto soil premix I'm guessing the roots are getting close the soil and nutes kicking in or does this look like another issue?

Buon giorno weed doctors, did anyone have similar uniform chlorosis at the top or maybe knows what's up? What could be the reason and the solution? ThIs this some sort of immobile nutrient deficiency or excess? Could this be caused by heat and light stress? She is 80cm tall and almost touches the lights in the tent. I'm usually suffering from Calmag and Nitrogen issues and haven't yet experienced yellowing from the top. Thanks

White spots on a few leavesAny idea what these whitish yellow spots are? They appeared overnight. I'm growing in ffof with perlite and ewc. No nutes added yet, just bush doctor cal mag at half dose 3 days ago with great white, recharge, and photosynthesis Plus which was the last watering of 1.2 liters.

Advise to flush or feed in VegDoes this is look like a nute burn, deficiency, or ph problem? The two plants that are growing a tad taller have had yellowing tips some curling downward. Don’t want to overreact and cause it to worsen, they’re looking healthy otherwise. Any advise whether to flush or feed?

Should I do full flush til runoff is 300ppm?So, it is obviously a deficiency, which probably caused by a lockout. Will the full flush solve it?
Yesterday I fed her a full dose of flowering nutes. Including K. It didn't change much. Lower fan leaves continue to go yellow.
Today 3L water, pH:6.2,
runoff:0.6l, ppm:1450, Ph6.0

Starting to yellowSo I had good growth up until 2 days ago when the one plant started to yellow. I had them going 24 hours a day and I got grow dots mixed in the bottom two thirds of the pots. Could this be light stress? or could it be hungry?
