Light streets? Or nutrient burn?
Lotigreenstarted grow question 2y ago
Hey, could this be stress from the lights? It starts at the top and barely shows at the bottom. The leaves are turning yellow from the tips towards the center. Especially at the top. It's under a 200w lamp.

It could also be a nutrient lockout due to an incorrect pH value of the soil, and as a result, the plant can no longer absorb nutrients. I would measure the pH value of the runoff and then possibly do a flush if it's not right.
- For the health and optimal growth of your cannabis plants, the pH value of the runoff should be between 6.0 and 6.5. This range ensures that your plants can efficiently absorb nutrients, preventing discoloration and growth problems.
- If the pH value is within this range, then it could be a deficiency as Organoman mentioned.

Seems to be a deficiency of multiple minor nutrients/trace elements.
A dose or three of soluble trace mineral mix, available from any good garden centre, applied to the roots should improve your plants substantially.

Unser erster Grow! Wir haben Nährstoffbrand, wie schlimm? Was können wir noch tun? - Dünger: Canna Terra Vega - Erde: COMPO SANA Qualitäts Eerde - 50%Exactly one week ago, we noticed a nutrient burn. The symptoms were initially quite mild, with a few yellowing tips. Now it looks like in the pictures. We already watered with pH 6.3 water without nutrients in the next watering. What else to do?

Yellow leavesHi guys, unfortunately because of an emergency I had to leave my 2 babys with some friends for three weeks. At the bottom some yellow leaves and like burning signs. I don't think it's because of over nutrition. They didn't get any for three weeks. Might be not enough nutrient?

Burn leaves? Yellow leaves? BIg problem? (AUTOFLOWERS)I had a problem with a lack of magnesium in the larger plant and I applied a little with a sprayer directly on the leaves, I got confused, I sneezed once on the leaves of the smaller seedling. Can I do something to resolve it? I even thought the LED was too close and I raised it

Does yellow leaves with red tips mean my plants need more nutrients or less? Jacks 3 2 1 on AutoWeek 8 (flower) top leaf tips are reddish and the leaves are more yellow than green. Does this mean that my plants need more nutrition?
I am using Jacks 3 2 1 for two autos and using it at 65% strength (650PPM / 1.2EC). Should I goto 100% at 990PPM / 1.9EC or 50% to 550PPM/1EC

Can anyone tell what is causing these yellow tips on new growth on this plant?I noticed my DLI was around 42 at the top of this plant so the light may have been too strong, or it could be a nutrient issue? Using CoM Stonington soil, plant is 26 days old. Haven't added any nutrients to the soil yet.

Your opinion?Today flushing the wedding cake i was thinking that the problem was an excess of nutrients, but instead water was quite clean, around 1100ppm at the first drain, after several flushes water is now on 600ppm. I also raised the lights.. I still do not understand 🤔

Lack of or abundance of nutrients?Shes doing really well but I noticed some of the leaves starting to get a little yellow so I stopped giving her nutrients and have just been giving her water for at least a week or two. She still acts like shes getting too much though? GDP auto x gumberry auto is the strain.

Mid Flower, Yellow, burnt leavesWhat could be happening to this plant? Could it be root rot or overwatering ? its in middle flower, with good ph and organic nutrients from top crop, 26°C and 200W led cob. This are the older leafs, but the rest of the plant seems fine. this week I increased the PK levels.

Is this light burn?Is this light burn? If not what is it?
It's under a Phillips 13w household led 2700k bulb, it's not the only affected area but it's the most affected and the closest to the bulb.
I plan to add more but don't want the issue to accelerate.
Thanks in advance!
