Is this light burn?

JoshuaTreezstarted grow question 3 years ago

All my leaf tips are going yellow, even on the bud leaves. It does seem to be a bit worse towards the top of the plant. Is this light burn? I am using 2x 1000w philzon LEDs in a 3.5'x3.5' Tent and I had them at 10/10 brightness. I just reduced to 8/10. Thanks in advance

Just about every hydro or soiless grows like coco and peat, have some browning of the tips of leaves in flower. If your white pistol turned brown/red early on in flower, say like 3rd or 4th week of flower. That is showing that the feed levels was a little to high in flower. Pistols should stay white for 5 to 6 weeks in. Cheers

Looks healthy but maybe just the tiniest overfeed? It looks like all tips are effected from looking at the background which is an odd uniformity, it may just be genetic or the start of a fade approaching the final stages. Have they dropped water consumption recently? Thats a good way to see if they are starting their terminal phase and starting to draw nutes from leaves.

Light stress can bleach but usually light stress leads to heat stress and the top leaves will usually canoe from the light and heat.

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.

Help, what are those weird yellow spots in late veg?Hello everybody, I've checked in on my plant after I was away from home for 2 day. Now I come back to see these ugly yellow spots? During day 23°C / 55% humid. During night 18°C / 50% humid. Checked the whole bud, but no insects. My other ideas are mold or stress from the light?
