Diagnose your plant. Check your runoff ph and ec levels, that tells you what is going on. Make sure your at the proper ph and ec if something is out of whack fix it and things improve. Ph tds reader is my main tool for big bud. Cheers

Nute Burn Plan. Lower light to 24 inches and turn on bloom switch. Flush soil with 8 litres of water (PH 6.5) per pot. Questions: will increasing the intensity of light increase plants ability to absorb nutrients, or simply stress them more? Is 8L water/ 10L pot enough to flush?Week 5

brown tips on some leavesfirst week of flower, only one plant out of five affected, only couple of leaves close to the top affected (up to 5 in total) - my assumption is 1. too close to light (I have 40cm between 400HPS which seems enough), PH problem or deficiency (potassium?)

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.

Do you think the yellowish leaves are because of nutrient deficiency, a nutrient burn, or just her fall colors?Week 14

Lockout? Can I remedy this late in the game?I think this is more than a K deficiency. I think I'm getting lockout. And a lot of it. She's an auto-flower, and I grow hydroponically. Can I even remedy it at this point?

Necrotic spotsThe last day or two I’ve had a bunch of necrotic spots pop up on the lower 3 sets of fan leaves. She is at node #5 now and starting to put out pistils. Is this phosphorus deficiency? I changed the res as it was close to a week anyways. Thanks all for the help. Happy Growing!

Just to confirm, this looks like nute burn, doesn't it?Burnt edges, tips curled up, canoeing. I've been having trouble balancing airflow and heat in such a small tent, and as a result the tent is on average about 28 degrees celcius daytime and the plants still get a lot of wind. Looking for whatever advice you can give! :)
