Yellow tips
ItalyGrowstarted grow question 4 years ago
Dont know why but one of the girls is suffering from stress. I think this is the cause for the yellow tips or do you have a other opinion? I did LTS training every two to three days, maybe therefore?
A other reason could be light burn. But with a distance of 50cm I dont think so

There are several issues that could be contributing to the issue. First, dark green foliage and clawed leaves (tip pointing down) that's over feeding, in this case Nitrogen. Second; 0,4 liters of water per day is too much at this stage. The yellow tips, it is probably due a minor element lockout (again because of over feeding). 5 Gallon of soil does not need feeding yet, wait until the plant consumes the nutrients in the soil and shows the first signs of deficiencies, most probably you will not have to feed more than once or two times in the whole run.

Dark green foliage + some clowing on the leaves = Nitrogen excess , I feel like you could experiment a N excess but it's not the answer to your question.
The fact that the yellowing in not starting from the bottom leaves to spread to the upper leaves makes me think that it is not a primary element ( N P K ) or a secondary element ( Cal / Mag / S ) deficiency , it would have start with the bottom leaves first so I feel like you have a trace elements deficiency , which one ? I'm not specialist enough to tell you that , sorry .
Looks like a K deficiency ( potassium ) but the older leaves would have been afected
It's not a light burn like you said , my Sticky beast started to burn when she was 5 cm away from my mars TSL1000 and even at 10 cm it takes a couple days before the burnt become serious ( and by serious I mean soft , I know what a hps burn can do so this one is a soft one )

Please help identify my Problem: Yellowing leaves with veins showing and some necrosis spots in third week of flowerThe odd thing is that only some leaves in the middle of the plant are affected. My thoughts were Nitrogen or Manganese deficiency or maybe light burn (why in the mid of the plant tho?)? I feed Biobizz Bloom, Grow and TopMax, no Problems until now.

Week 8 (4 weeks into flowering) - Possible Nitrogen / Cal-Mag issue?Plants show signs of what i assume to be a deficiency. Stopped feeding nitrogen Week 7 according to schedule. Symptoms are not on every leaf but some the upper foliage. Yellowing, burnt tips and rusty spots. My guess is lack of Cal-Mag & Nitrogen. Is my guess correct?

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.

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.

Yellowing leavesLower leaves are turning yellow, these seem to be one that are hidden a bit from sight, so possibly not getting enough light, but it seems to be spreading, and one of them has fallen off. Is this some form of nutrient difficiency, or something simipler?

Lower leafs getting yellow tips and spotsI just noticed that the lower leafs are dying, while other leafs are getting yellowish spots. Is this some kind of nutrient deficiency? The leaf with the yellow spots is near the air intake.
They didn’t get any fertilizer except root juice since the soil is still somewhat fresh.
