Leaves curl on upper new growth and mid but not lower.
Dankbudz84started grow question 4 years ago
I’m using the canna coco line except boost, looks like phosphorus deficiency. I just lowered my a and b 0.7 ec and added 0.3 of pk for a total of 1.0. Is this phosphorus deficiency and do you think my changes will help. Leaves are a little dark shinny and the shape is odd.

Hi your leaves are like that because of to much Nitrogen at some time during the grow. You have now lowered n and increased p and k so it won't get any worse. Leaves won't recover and will look like that for rest of grow, newer leaves will look a bit better. Shouldn't harm your grow to much as you have spotted and corrected it before it got to bad.

Weird Leaf ProblemNew leaves show strange twisting/curling. Humidity ~50%, temps 28-21°C (D-N). Did LST last week—could twisting be due to reorienting to light? Using All-Mix soil, Bio Grow, Calmag. Water left 24h, not pH'd. Some leaf holes caused by me. Flipping soon—help resolve this issue!Leaves. Curl up

First time growing/Need help in late flowerOver the last 9 days my plant has gone from happy and healthy to sugar leaves pointing straight up near the top of plant and drying and curling up on the lower levels. Is this from too much light or did I over feed late in flower? First grow/ no diary. Can I save or do I chop?Leaves. Curl up

Some leaves are showing small burnt spots and slight curling. what could be? I'm currently dealing with Fungus Gnats in the grow. I applied Beauveria and covered the soil with burnt rice husk. I’ll wait for the soil to dry and then use hydrogen peroxide to try eliminate the eggs.Leaves. Tips - Burnt

help in Hydro RDWC/DWCHello, my plants are now about 4 weeks old. The leaves droop and curl. The spots on the leaves are increasing. Is the PPM value too high? It's 1000ppm tds
They grow in an RDWC system with top feed. The top feed is permanently switched on. Can that lead to problems?Leaves. Curl down

Regretted ovewatering guy. Still bot enough?Hi peeps, a regretted ovewaterer here. Is It normal to wait 10 days in between waterings?
