Leaves curl, become crispy and have weird colors
I need help. I've not had this problem before. The leaves get crispy and have weird colors. However, the buds continue to develop as usual. What could it be? Not all plants are affected. But it spreads slowly.

Brown Rusty Dots
What are these brown dots on my plants? They are only on one of the plants, they have gotten a spray with Dr. Zymes Eliminator and had no effect, also did a mL of Cal Mag in its last water with no effect and getting worse. I’m not sure what this is and I can’t get it to go away!

help in Hydro RDWC/DWC
Hello, 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?

Top leaves turn dark and curl - What can I do?
I've had Nitrogen and possible Cal/Mag deficiencies 2 weeks ago. Mid last week I started noticing some burn a the tips, so i dialed nutrients back again. By this weekend the tips of the leaves curled further and turned dark. The rest still looks a bit pale, but buds look good.

Leaves looking f’d?
What’s happening with these leaves? It started last week and has spread. Only the leaves in the middle under the light. Week five of flower. Was using the same nutes and strengths since flowering started at 6ph. Upped the strength this week to see if it would fix and it got worse

Is this Phosphorous deficiency or overfeeding?
It happened from day to night, the watering with Fish-Mix and Bio-Heaven was made days ago. Otherwise, I haven´t feed her any bloom nutes yet. Peace ✌️

Dark green leaves in meringue
Is my girl telling me that the flowering fertilizer is too nitrogen loaded? I´m using top bloom from top crop, feeding at 1.4-1.6 Ec, and since last week I started to follow the feed-water-water schedule. The NPK of this fertilizer is 4-8-8. Should I adjust the input EC?

Leaf tips are browning
Ciao tutti, What is going on with these leaf tips? It’s the third day of their Flush & It can’t be NutBurn, or the color of tips doesnt look like NutDef! Is the light stress? If this de-coloring continues, will it effect the buds & final yield? Thanks
