Brown spots and yellowing leaves.
deckeron73started grow question 3 years ago
I’ve just started to get these brown spots and yellowing leaves on the top leaves of one plant. Not sure what it is, potassium or calcium deficiency. Soil ph is 6.35. Water with regular nutrients at a ph of 6.5.

If you have been adding cal/mg every feed, you likely have some lockout going on. Check your runoff water for the ec and ph. If your ec is gone overboard, the cal/mg is likely the cause. Very little needed in the soil once they start to bud. Check the ph as well. If this is out then it also creates lockout. It is definitely not a defficiency my friend, well it is but caused from locking out the roots. Cal/mg has lots of nitrogen as well and that is something the girls don't need much of once in flower. Cheers

Week 2: One of the plants still doesn't look good + other beginner questions :)Second week and one of the plants has weird spots + leaves curled.
Not sure what to do. Do I overwater? Is it some kind of disease or deficiency? No idea.
Also, when should I start feeding the plants?
And how much water do I need at this point? 😥

Healthy?Sie wachsen zur Zeit sehr schnell allerdings haben manche Blätter Flecken wie man sehen kann. Die ersten Wochen habe ich leider mit einem zu hohen Ph Wert gegossen (ca 8) dies habe ich jetzt aber angepasst und sie bekommen ihre 6,4.Vielleicht Nährstoffmangel? Bio Grow hinzufügen?

Plant not growing anymoreYes I made a mistake with bottled nutrients and burned her. She is in nutrient lockdown and im flushing her for a week. But she is not growing anymore.
Leaves are all curled up and brown on tips because of nute burn.
My question is should I leave her or should I cut her?

Is that not enough calcium?How can I recognise that it is only a calcium deficide? The plant is also the largest and the only one with such deficiencies. Could the plant also be lacking manganese or magnesium and what can I use to compensate for this? Are pests or diseases excluded?

Brown Spots on LeavesI’m noticing some light brown spots on my leaves. After researching it seems that it was either 1) Manganese deficiency 2) calcium deficiency or 3) overwatering. I don’t think I’m overwatering. It could be the nutrients but would like input!

Top leaves turn dark and curl - What can I do?I've had Nitrogen and possible Cal/Mag deficiencies 2 weeks ago.
Mid last week I started noticing some burn a the tips, so i dialed nutrients back again.
By this weekend the tips of the leaves curled further and turned dark.
The rest still looks a bit pale, but buds look good.

Too Much Light?Top looks yellowish, more so IRL than in the pic and the new growth is kinda taco-ing. Just under 24" from the light, 78F and using Photone the DLI was at ~30. I don't really trust that app but if it's even sorta accurate, 30 might be high with no CO2? says their charts anyways.

Why do my plants only have that light greenish yellowish look at the top and why is one of my plants also having those sick leaves at the bottom?2 of my 3 plants are a bit yellow-ish at the top since about a week. Plant 1 also had a couple of sick leaves at the bottom that I did remove. Those leaves had brown/dark spots, felt dry like paper, had very purple stems and did smell more like hay. More info in my report.
