Slight burn. You're feeding MORE than the manufacturer recommends and manufacturer recommendations are notoriously over what your plant wants. Dial it back a bit, see where 4mL/L takes you after doing a water only feed or two.

Deficiency?
So I noticed this yesterday and I'm struggling to figure it out. The symptoms only appear on a few leaves of only 1 branch. Nothing about the environment or feeding has changed. A recent flush of plain pH'd water showed slightly acidic soil but not too crazy. Bottom feeding with

Dry yellow tips
I've noticed a few leaves have developed some dry tips on the ends including some of the new ones coming through. Can anyone tell me what could be the problem? Feeding bio grow 2ml per l at the minute. Is it a deficiency of some sort? Or nutrient burn? Worth sticking to water?

Getting out of the ideas - VPD, nutrients or deficiency?
I'm getting out of the ideas as the foliar symptoms proceed. Lowered EC down to 1.8 from 2.2, pH in range. VPD is getting problematic as the plants seem to be respirating a lot during the day and it rises tent RH sometimes up to 70% - exhaust duct fan wont keep up. Temps 22-24C

Burnt bottom leaves
Found burnt leaves in all three plants. They are all from the bottom and fell from the stems. Not sure if it's a)lack of nutrients b)nutrient burn c)nothing wrong, just the normal process for shaded leaves. What do you guys think?

Nutrient issue or high heat?
I believe I have an over nutrient issue or could this be due to high heat? My green house maxed out at 122 degrees, typically it reaches 105. The burnt tips showed up a day after the first nutrient feeding. Plus I have sheep manure and Iron earth in my soil. Did I over do it?

Heat or deficiency? Or something else?
I'm noticing some sort of deficiency or toxicity. I need help on figuring it out. I water with distilled water, cal mag, and 1/2 strength bloom boosters. Ph @ 6.5. Could it be heat? It gets a little over 80 F. I have AC running, It's still cooler than outside in the sun though

Yellow/Brownish colored tips of leaves.
So, my girl now is 11 days old, while i was looking at here i noticed that the tips of the second pair of true leaves is soightly yellow/brownish colored, im worried for my plant. Could it be a wind burn ? I have a ventilator in my tent which was blowing at here. I moved it now.

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! :)

Are there any reasons to worry about these spots? And somehow on these two side leaves, the tips have darkened?
