DWC minor leaf curl up

Hoodoostarted grow question 4 years ago

1 out of 2 plants is leaf curling up. This started occurring after nutrient change. Humidity = 50%, ppm = 570, temp = 80F, EC = 1.2. I realized the lights were 21" instead of 24" so I raised the light. Should I be worried? This one is slightly darker green than its sister..

Hi mate, I have been doing DWC and usually when I couldn't determine what the problem was, I had root rot. Can't be sure but from the pics of the roots you posted on your diary seemed to me like the start of root rot. Check the smell of the reservoir and the roots. Check the temp of you water. Most of the times the main factor for root rot is high temp water and lack of oxygen which are related.

Day 20 Flower. Leaves curling Leaves curled over 12 hour light cycle. Ph 6.0. Ppm 950. I have been battling ph drop for a week. Lowered Ppm to 900 from 1100. Seems to have stabilized the ph and now the leaves are doing this. I’m looking to do the day 21 strip of most leaves tomorrow. Should I be concerned?

Looks like light stress I assume with the canoe and curl. Moved light from 100% to 75% Stil at 35in from canopy. Should that do the trick? Also should I have already had it at 75% and moved it to 100% during flower? Or how do you guys do your light power

Surplus or deficiency?Can't tell if there's a surplus of nutrients or a shortage of potassium? One plant looks like nitrogen burn and the other two look like theyre maybe a little k deficient. Was thinking of chilling out on the feed on the burnt one and just feeding micro to the other two. Thoughts?

Week 2: One of the plants still doesn't look good + other beginner questions :)Second week and one of the plants has weird spots + leaves curled. Not sure what to do. Do I overwater? Is it some kind of disease or deficiency? No idea. Also, when should I start feeding the plants? And how much water do I need at this point? 😥
