I think 30cm is awfully close for your light but without knowing more info it's hard to say. Nearly doubling your EC might have been a little aggressive, I do see some tip discoloration on the leaves but that could just be poor watering habits. Start a diary so it's easier to diagnose.

Not answering your question, just a note: "lamp height around 30-35 cm" doesn't say anything at all, what is your PPFD?
Burnt tips could be due to heat stress, light stress, over feeding...
Curling down leaves could de due to Nitrogen toxicity or simply overwatering .. and so on
Yellow spots on one leaf could be magnesium deficiency..
Bottom line - you gave too little initial info to make any educated guess about issues you plant is facing

Older leaves are yellowing, brown/red rusty spots, dying tissue, red stems.Older leaves have brown/red rusty spots and looks like dying tissue in between the veins.
Burnt tips, and yellowing leaves.
The soil was really dry and my PH meter was 0.4 too high.
I gave each plant 3L of water with EC: 0.0 PH: 6.4 to check runoff.
Runoff was PH: 6.1 EC: 0.8

Rust colored spots on the oldest leafsIs it phosphor deficiency or cal deficiency? spider mites? It’s time to change the water of my rdwc system anyway. Should I flush before changing? Should I add more calmag then the previous time? Some leafs have gotten curled down tips. It’s my first grow btw. Nutes: GHE tripart

leaves diagnosticWow, great news from my plants. Some of them had signs of either nitrogen excess or excess water. I realised that it was probably caused by both water and nutrients in excess. The soil to compact and dense was the problem, much better now.Week 3

Small brown spots on leavesThis plant is now 6 weeks into flower in a 5gal dwc bucket and after changing the water yesterday these spots started showing up this afternoon but only on a handful of leaves. Am I looking at a deficiency and if so what would be a good remedy or additive?

Leaves of plant are clawing but not sure on the reason why. Suspected nitrogen toxicity as nutrients have 2.1% nitrogen and was feeding everyday. Have laid off.. and will be doing twice a week. Is this right? It is the only thing I can think of that is causing clawing..Week 1

I grow 60% coco and 40% biobizz light mix (soil/perlite) I've been told by a grower to aim at a ph of 6 and not water until runoff due to my medium composition. Someone also said N deficiency.

Yellow/burned tips & curled leavesI have an issue with some yellow/burned tips and curled leaves.
I already suspect that mainly is from light stress but could also be a nutrient deficiency?
I´ve raised the lights the max I can and keep it at 80% for 20 hours.
Biobizz soil and nutrients.
Thanks in advance!

Turned down leaf tipsHi guys! Trying to understand what is happening to my plant. Leafs look really sad. Thought it was overwatering but nothing changed after a couple of days without watering. Can it be nytrogen intoxication or something like that? I use GHE fertilizer and stick to instructions
