All you had to do was dim it or raise it higher. If not dimmable then distance to reduce intensity is only way to solve it.

Really doesn’t look like light burn to me. Especially running blurples. They are not especially intense. I think you have some feeding / pH issue possibly - if anything.

How do you harvest in hydro (drip system with a tank) when some are late ?
Half of the plants are late (chlorosis, iron toxicity, nitrogen overfd) on a scrog net. As individual flush is impossible, I guess I have no choice than having different batches of ambered trichomes ! And I thought about different strains next time, sweet dreams...

Damaged leaf
The damage leaves from yesterday looking worst today. Someone of the experienced growers can define the problem? I Adjust the light to 25% and about 40cm high like suggested from @m0use. Is this a clear lightbun or can i be something else? Thank you very much :D

What am I facing? Plant is getting worst everyday, and I can't find the reason why. Thought it was a calmag def, but now I don't really now.
When I switched to flower, I started watching some rusty spots on the leaves of the gelato. After doing some research, I thought I was facing a calmag deficiency, and starting adding some calmag. Plant is getting worst, I flushed the roots and water between 5.8 and 6 as canna ask

Light burn ?
Signs of some sort of def or light burn? My full-spectrum COBs and bulbs are putting down ~22.000lux at the canopy, is that too much at this stage? Autoflower Green Gelato Day 24 Can’t think of any other problem besides the lights...

Nutrient lock out?
Well watered my plants with great value drinking water. Ph 4.11. Didn't check ph until week 3. Currently upping it to 6.5 after I found the issue. Does this look like nutrient lock out? They were in root Riot starter plugs. And I fed the some clonex and great white microbs.

Harvesting a struggling plant or just letting it fight
Can she be saved or just flush her and harvest what I can? She doesn't appear to be happy. Has some CBD genetics so the lack of trichomes don't worry me. Rest of my garden is fading as well. Flushed em last feeding and they didn't seem to like it.

Can anyone help identify this tox/deficiency?
Week 6 I noticed that all the new growth has burnt tips I assumed this was a bit of a nitrogen toxicity problem since the leaves were all a nice dark green, no pale leaves were popping up. Also held back on feeds for a few weeks. Other forums said it’s normal but want to be sure.
