Day 33. Got leaf burn. See attached close up photo...
OutForRealanswered grow question 6 years ago
Hello ! Well it's looks like a phosphorous deficiency to me , the brown necrosis on the leaves are a sign of P def. But as your plant looks healthy and only one leaf is touch then I think you had some water on the leaf ( 2 or 3 drops ) which created a loup effect and burn the plants. I hope it's not a phosphorous def but it's too early to really say I'm 100% sure. Hope it will help you đđ

Calcium Deficiency???So this is a Calcium Deficiency right? Noticing on top leaves. Not bad yet but want to stop it before it starts as this grow has been my best so far. I have been using CalMag every water but I did lower the dose for a few days as I was told I was using too much for flower.

One plant (the one on the right) is going yellow, with brown mottling on the leaves. Both plants have been treated exactly the same.
Iâm giving the plant some calmag and extra nutrition after flushing it (which had no effect). Any ideas to save this plant? WorriedâŚ

Look At This Pigmentation!Lower fan leaf vs upper fan leaf in the canopy. The difference in pigmentation is wild! It almost looks like its bleeding.

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? đĽ

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 LeavesIâm 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 donât think Iâm overwatering. It could be the nutrients but would like input!

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.
