Bright leaftips, necrosis and other problems...

Hey there!

First of all here are some informations about the plant. Its a Auto Brooklyn Sunrise from dutch passion. She poked her head through the top of the soil on 13th March. 19 days old. I watered her only with tap water (its quite good where i live but yeah...). Pictures at the bottom.
Cant give you the ph or EC since i cant measure it. She is under 1 Cree CXB3590@50Watt with 20h/d light since the beginning. The soil is Plagron Light Mix.
I added this product (https://www.amazon.de/gp/product/B00A9TMABO/ref=oh_aui_detailpage_o04_s00?ie=UTF8&psc=1) to the soil and mixed it and i additionally added it at 2/3 of the height of the pot as a thin layer.

No problems with anything in the first 12 days. Since the last 7 days i got problems. New leaves have really bright leaftips. Older leaves got some slight necrosis(?). Some Fanleaves wilted up but i guess its from heat stress. Some new leaves of the budsite starting clawing like a N-toxicity.

Possible problems might be ph issue or the tap water beeing not quite good but i guess i would have had these problems since the beginning. Another option is that the Roots hitted the thin layer of the fungi and it was too much.

If it is a defiency in any form i could help since i have a few hesi fertilizers near by but i think it will kill the fungi if the tapwater didnt done it already.

I really want some help since i really dont know what i did wrong this time.#

Have a nice sunday
bye

It looks like PH lockout.

Looks like a few problems. Nitrogen burn in one of the pictures, and a micro deficiency in some of the others. Lighten up on the feedings, ph your water, and foliar feed some ej microblast. You should see new healthy growth with a couple days.

i only "feed" tap water. Its only the mycorizha in the soil...so i cant go much more easys on my feeds.

i gonna buy a ph-meter and ph solution. iam going to cook the water and filter it through a RO filter. then gonna test ph and flush the soil.

Keep in mind, earth juice microblast has no calcium. Those look Ca deficient as well.

Could be and definitely wouldn't hurt to throw some cal-mag in too. Microblast will solve 90% of micro problems and is always my first go-to remedy when I see anything resembling a micro nutrient issue.

thanks for help. iam gonna have a good water source first and gonna flush them. then i need to spray them with microblast or something similiar since i cant get my hands on that where i live...

You can brew a compost or earthwormshit tea to spray down the leaves in the meantime.

thanks for the tip iam truthful here: i dont know how to do it. brb reading into it


i could get my hands on a biobizz indoor pack...would that biobizz grow help my plants as well?

check youtube

I'd have run the biobizz from the start, I think it needs a little more time to start breaking down than the chemical salts. I am keen to try the line, but can only get the 3 main parts locally.

i bought the biobizz indoor pack + ph meter + ec meter + RO filter. iam gonna buy citric acid as a ph-minues solution. iam going to boil the water and let it run through the ro filter. then iam going to let it there for 24h and measure the ph-value and add citrusacid if needed.

would that work for a good water basis for the plants? i would flush them with that kind of water and after that feed them lightly with biobizz grow.

sounds like a good plan?

Just keep the nute levels low, it is better to recover from too low levels than too high.
