Hello. I’m from Russia, ru-community couldn’t help me with this problem. Hope to find help here! I use google translator, I apologize in advance for errors in the syntax.
I hope for help, because my hands fall already.
From the beginning, from the sprout, yellow spots began to appear on the leaves of one plant, which then blackened, spread throughout the leaf and the leaf naturally rotted. Please note that this problem started from the beginning, when there were still no fertilizers, there were no problems with temperature and humidity, but the substrate was the cheapest land from the store.
I watched further, the lower leaves died off, the disease climbed higher, onto initially healthy green leaves. Symptoms are similar to a lack of calcium, so I began to pour in pH 7.0, water pH 5.2 came out. He also began to give GHE fertilizers, but in smaller quantities, so as not to additionally injure.
At the last watering I saw a small white bug in the ground! Who can it be and can it be the culprit of the problems ??
On the second plant, everything was ok from the beginning, but now there are similar symptoms, maybe still the problem is in pests, and not in nutrients? This is the second plant
