hello, at the beginning I would like to point out that I use a translator but I hope that we will get along, for many months and many attempts I have problems with seedlings, I spent many hundreds of hours learning and analyzing my problem, thanks to the trials I learned hydroponics, both passive and dwc method, I remember about it just so that you don't consider me a total amateur who pours a gallon of water with fertilizer into a seedling as for a large plant. The problem with my seedlings is that after about 2 weeks they stop growing, both the roots and the rest of the plant, then the lower leaves begin to wither and slowly move up, the plant seems to be blocked, it happens in any type of substrate, from different soil producers to different hydroponic substrates and this only happens with hemp and tomato (supposedly tomato is very close to hemp) other plants grow healthy and without problems in the same conditions, I used many variants of soil, plagron, biobizz, canna, soil with flower shop, weaker and fertilized version, there was coconut, mixes with perlite, I cooked coconut, I did everything that came to my mind, I changed seed stores, I changed varieties, lighting from fluorescent to led ts600 and ts1000, I changed types of water until I bought a filter RO3, I used digital and drip pH meters, of course they were calibrated, and the EC meter, I used beneficial fungi and bacteria, I did everything possible e changing variants not once and not twice but several times and I still fail sadly, it takes more than a year, everything else grows beautifully except hemp and tomato, do you know the disease of house plants that may kill hemp seedlings while the ornamental plants themselves can live ? or maybe there are types of plants that hemp does not like? people advised me basic mistakes that I overwater ... I made a lot of attempts and followed the recommendations even when they were idiotic, I followed every advice, weighed the pots, sprayed instead of watering so as not to overwater (although it's hard to overwater a plant in hydroponics ) and still I fail and there was a beautiful pepper next to me that gave me fruit without any great effort... have you ever heard of such a case? I will add that I care about cleanliness, I was always surprised watching the photo report how people can get dirty but still they enjoy healthy hemp, I have a few ornamental plants, I'm thinking of throwing them away, wait a month and try again, I've already spent a fortune on the seeds I downloaded not only from various stores in my country but even from the RQS manufacturer from their warehouse, fertilizers (biobizz, ghe, canna, biotabs, root additives, additives in the form of beneficial bacteria from the Bacillus family), electricity, equipment and nerves ... because it's really sad and the worst thing is that everything you can think of i've already done it, changed it, corrected it, checked it, even moved the cupboard to other places in my house because i already considered the impact of energy vortices, i know it sounds like crazy and madness but imagine 17 months of continuous attempts ending in failure, the problem is not me and things like overwatering, overfertilization, I changed all that, I kept notes with sem pH and EC and the amount and size of watering together with the weighing of the pot, have any of you encountered something like this personally or through your friend? I will add that there are no symptoms of root rot, if it was an overt pathogen that would kill hemp and immediately peppers, I would be happy to have the culprit, but peppers, geraniums, kitchen herbs, catnip, everything grew without a problem, I had catnip in dwc in one letter jar and grew to such a size that it covered half of my 40 inch TV, and hemp? it dies over and over again and always the same way, I've never had a cannabis taller than 20cm with more than 6 tiers of leaves, not once.
