DWC minor leaf curl up
Hoodoostarted grow question 5y 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.

Hi guys, I’ve noticed the leaves of 2 plants are curl upwards. I think overwatered, Day 9 I’ve watered two times (wrong) and after checking Day 8 too. At day 10 I've didnt watered, and today I've seen the soil dry, so I putted 100ml water. What do you think is causing this curl?Week 2

Week 8 (4 weeks into flowering) - Possible Nitrogen / Cal-Mag issue?Plants show signs of what i assume to be a deficiency. Stopped feeding nitrogen Week 7 according to schedule. Symptoms are not on every leaf but some the upper foliage. Yellowing, burnt tips and rusty spots. My guess is lack of Cal-Mag & Nitrogen. Is my guess correct?

While I wait for new pH meter give less liquid ferts (to avoid pH problems) start from 7.3 then don't know where it goes prob somewhere between 6.6/6.Hi! Lower leaves=N def caused by flush prev week (due to build up), crispy yellow tips=P def? pH pen dead, watering blind, that's the main problem, using pH strips test.... 🤮
EC in 1.5 runout 1.9.
Using Solid+liquid ferts (low dosage rn). Still stretching, looks healthy. Agree?

Issues with leaves. Day 90 total, 30 of flower. Leaves have been getting more and more yellow the past week, with progressively more brown tips.Vpd has been pretty close to ideal, the pot had 1 gallon less soil so could be missing out on some nutrients? Possibly Potassium? Otherwise not sure what it could be. Does not appear to be N deficiency because the leaves are affected from the top too. What should I do to fix this

Brown rust spots on oldest leavesBrown rust spots on oldest biggest leaves with curling inward - the rest of the flower is fine, just some occasional small yellow spots. No sign of pests. Maintaining pH ~6.5 but have soft water. Suspect cal/mag deficiency or nitrogen toxicity. Thoughts?
