Don't worry, just cut the damaged leaves and be careful with the nutrients you are giving and the pH of the water (5.8 to 6.2PH). sometimes less is more.

Still K deficiency?I fed some flower fuel to plant 1, half strength, and the discoloration got worse! Some leaves almost look like cal deficiency so I also sprayed foliar with calmag, just now when I got home. Is this still looking like a K deficiency? If so, should I feed it again or wait?

Brown spots on bud site leaves?!halfway through flower and now in week 6 flower one of my plants is showing some large brown spots on only the upper leaves. I’m not sure if it’s a light or ph issue as the light is close. I stopped cal mag and some nitrogen this week but spots were showing up before.

What could this be? Deficiency, or pests?White Crack in coco, currently late veg / pre-flower stage. Canna nutes being fed at EC 1.7 / pH 6.0 with runoff EC 1.3 / pH at 6.2. Noticed this on a single leaf this morning. Only change in last few days is that I am now filtering my water before mixing in nutes. Any thoughts?

Root rot or pH imbalance?This blueberry muffin (f) plant was doing well until last week when it started deteriorating. Its grown on a mix of cocopeat, vermicompost, perlite mix and fed on compost tea and cal-mag mix. I might put it down eventually but I checked the pH and it was 5!

Taken a few pics of one of the affected leaves.
Thinking potassium deficiency but not 100% sure
Was away for best part of a week & had someone else watering them, just plain water (may of spilt on leaves?)
Leaves seem crisp to touch as well as the yellow/brown colouring.Week 5

Calcium, lock out?Hello, it looks like calcium, P, or K issues. Maybe pH lock out. I flushed last week and followed with nutes. Likely last nutes this week followed by a week or two of flushing before harvest. Please look at leaves and let me know what I should do as I end off this plant.

Brown spots and yellowing pictured above. My best guess is a Cal/Mag deficiency. Was feeding Botanicare Cal-Mag Plus at 1 ml/l up until ~2 weeks ago (friend has been watering while I was out of town). Before I feed her, any advice on what the problem is and how to correct it?5y ago

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! :)

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?
