add grow + bloom grow contains nitrogen
how many ppms are you feeding them? they look hungry.
I thought I’d be over-fertilized I dated it from the beginning of the fertilizer flower according to the table from biobizz + cannazym + pk 13 + 14 … almost for weeks i have been reducing ec before the week here i daval 1.4-.1.6 ec a ted down the last wrapping yesterday meli 0.8 ec
if you are feeding then it could be a lockout preventing them from getting the nutrients, definitely looks like a nitrogen deficiency
biobizz light-mix is a fertilizer so do you mean you are growing in soil WITH biobizz light-mix or in pure biobizz light mix??
You can apply larger quantities of this fertilizer to any kind of plant, including heavy feeders, without the risk of overloading the soil and causing a nutrient burn – indicated by yellowing and crunchy, burnt tips on the leaves. With automatic watering it’s important that the water properly infiltrates the substrate, or this can become too wet and cause mould to form.
that’s the only information i could find on the biobizz product page, i can’t find ingredients or anything else on the data sheet so i’m not sure.
used soil is biobizz light mix
what’s the PH and PPM of your runoff?
want to ask if I want to fertilize every day or two days water and then fertilizer and then again for two days water … I will almost every weighing but sometimes something else need alg.a.mic + heaven … the next day is bloom + pk. another day grow + top max example …how I can fertilize to save them
ph outflow or discharge I did not measure no podmisky so it flows to the floor so i do not try to measure the day and accordingly I will subtract
the bottom leaves are whole brown and dry, and they are yellow and have brownish twisted tips such as lack of potassium or
I just start mine in bio-bizzz’s 'all-mix soil, never had any problems with any seedlings 
& it keeps em fed for a few weeks. Looking like N deficient , Good luck

Edit: just re-read your post…:: Give it a flush or leave off the nutes and give em water 
for next few ‘feeds’ as too much happening in the soil, probably fixable, but if they get worse then I’d flush…
Haha hustá czenglish 
more N i think. Dont overwater them
