Grow QuestionsIs this light burn?

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.

Yellow spots on leaves Noticed yellow spots on one of my leaves. It’s just on one plan (just one bottom leaf). Don’t know if this is cause of water being on the leaf or something else. Might just cut the leaf but I wanna know what it is 😅😅

Balcony Auto Gelato with Yellow and Brown Leaves I'm growing this auto gelato in a balcony safe from rain fall and harsh wind, it's the 25th day and the bottom leaves and cotyledon are turning yellow and with some brown traces. I started to use minimum amount of "all in one" fert. Do you think it is overfertilization issue?
