first grow, leaves problem

[Peebles]

Problem: lower leaves burning

Medium/grow method: soil Plagron royal mix

Feed: and supplements used: nothing yet

water source: distilled water at 7ph

Strain/age: blue cheese from Barney's, day 26 since planting the seed

light used: in a 1M X1M X1m80 tent, under a led viparspectra 450w at 50cm 20/4 schedule / extractor fan with carbon filter

Climate: 27/28° C by day , ~20°C by night
40° RH

Additional info: Hi , since a week or so, lower leaves are burning, watering every 3 or 4 days, wondering if it's underwatering, rh to low, or just the royal mix being to hot? It's happening on only 2 of the 4 I have. Any ideas?

Clay pots dry out quickly so make sure they are watered fully.You could start light dose of veg nutes but lower your water to 6.5 or close to it.

Thanks! It seems that the pot dry out pretty quick indeed, Will water maybe more frequently and lower ph a bit too.
Should I removed this leaves by the way or just wait?

Be careful misting under LED. It could easily burn leaves. It looks like those tips were possibly resting on the soil, in turn burning from LED.

I wouldn't remove leaves. I'd rather monitor effected leaves. If you remove leaves and haven't taken care of the problem other leaves will become effected.

Just leave leaves alone for now and wait until she gets a few more leaves than remove the bad leaves.

Plagron Royalty looks like it might be too hot for seedlings,... nothing to be done now, just keep them nice and moist,... newer growth looks OK, so that's good,... those lowers may get burned out eventually, but don't sweat that,... consider getting a quality pH soil probe, like the Accurate 8 (Control Wizard) or equivalent overseas,... some other folks in EU found the same unit, might be under a different name, but they look like this-

... avoid the cheapo skinny probes, multi-meters, etc., they are lousy for accuracy,...
In the future, you can make a milder mix using that soil and some seedling mix, usually just peat and lime, perlite,.. blend it 50/50 and make about a 1qt size pocket in the final pot to put it in.. I like to use large solo or styrofoam cups, 24-32oz for this task.. just stick it in the big pot, and fill around it and remove, add mild mix, and sow,...
