More rusty spots

Goenndalfstarted grow question 4 years ago

See this now on more and more leaves. Only upper fan leaves that get good light exposure seem to be affected from this and also the clawing. Have backed off the nutes completely for now and will add ground egg shells to the water in the hope its a Ca deficiency.

Looks more like a potassium excess, better off doing a semi-flush with some stimulators in the water like Root enchancers and/or humic acid.

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?

The leaves are curled up, it's hot in the room these days, I guess this is the reason. Plants growing fast anyway, humidity between 48%57% but I'm worried because of this leaves problem. Should I ? I do my best to cool down but can I do something else ? Mist the leaves ? Thanks !

Might this be a Calcium deficiency I'm having?

I flushed it because some leaves were showing some Nitrogen Toxicity. Run off was coming at 3000ppm and I fixed it to 1500. Now the older fan leaves are yellowing with some brown spots (check the last picture). It's a deficiency? Should I increase nutes? Thank you very much!

If I’m correct but who knows that most likely over watering or my lights are to close?

Any ideas on my lower leaves cupping? I'm thinking a root issue from overwatering. I last watered 6/11 and this started showing on 6/13 and has progressed. Soil is still moist and fungus gnats popped out of nowhere this week as well. Have SNS 203 for next watering

I water my plants everyday , however I have mixed my nutrients “ph perfect grow, micro, and bloom” in with my water only the appropriate amount given on the bottle. Should I be using water with the nutrients everytime I water or switch it up with plain water as well?

Some brown spots showing on the top sugar leaves. I suspect it is due to the cooling fan of the light blowing down hot air? I've adjusted the fans to blow air directly over the top of the main cola's and I increased the light distance.
