Sick Baby

One of my babies has developed brown patches and they dry out and go crispy (necrosis i think)
Its only a few weeks old.
Any idea whats causing it?

Forgive me but i haven't grown anything in a couple of years and out of practice

Regular photoperiod.
BioBizz Light-mix soil
Watered roughly every 48 hours (or when soil is dry) with tap water. I live in a hard water area
Only nutrient used is 0.5ml liquid seaweed per litre of tap water.
Temps are min 22.C (71.F) to max 29.C (84.F)
Humidy is min 46%, max 70%
Light is 150W led about 60cm (2FT) above plants

84 is a bit hot, don't let the soil get too dry. Bring the lights a bit higher until they recover. The burned parts of the leaves won't recover so keep an eye on the new growth

Whoo hoo ,it's the wild west,yee haw

No more seaweed nute for a bit. Looks plenty green. I have temps up to mid 90`s and no problems. Light height is good, lower once stabilized.

What is “ All-mix soil “ ?

Everything else about grow is negligible - that leaves the medium ( soil ).

I would start to feed

Bump
Anyone got an idea?
Sorry to ask again, but 1 post said to hold off the seaweed, while another post says to feed it.

Is seems to be a deficiency of some sort, if i knew what i could try and fix it

You're using biobizz light. Youre seeing deficiencies because you're supposed to feed more than seaweed by now in your grow. You need to feed actual nutrients. You can get this info straight from biobizz.

brilliant, thanks mate, i will start the fish-mix tonight.
Gonna pot it up into All-mix at the weekend
