Big mistake this week…I wanted a light feeding for the plant and Finally I caused the opposite effect: burning the plants by a nutrients excess. Soon I saw the first symptoms and after some researches to confirm my feeling: the diagnostic seems clear: nutrients overdose.
Reacted quickly and flushed the plants 2 times with water ph 6.3 (1/4h between the 2 watering). All old leaves extremities where burned and dry, new leaves turned in acid color and were burning too. I was sure that this session would be lost during 4 days. Today the plants are looking good, growing normally. There is no time to loose with auto flowering strains: a mistake impacts directly the final harvest, impossible to extend the vegetative period and stabilize the plants after a shock.
New light: TS 1000 Mars Hydro 24h/24: more heat in the grow tent= More frequency of ventilation and air extraction.
The CO2 booster (BUDDY BOOST)is installed.
