Grow #2 - First Time Indoors

The bag seed experiment plants were topped and set up for mainlining. Never done mainlining before, planted these throwaway seeds from my outdoor crop just to practice with it for my next grow. The tops recovered and kept growing strongly from the get-go - this one looks to grow vertically strong like a sativa. Not sure how long I’ll keep them, probably until space becomes an issue. The feminized seeds were all topped. They are responding slowly to the topping and are shorter/bushier anyways, but the tops are finally growing out now. I have a mutant - one of my GDP plants has a mixture of mutated leaves (4 prong) and mutated tops (tri-tops that each randomly show both symmetrical & asymmetrical nodes). Not sure if I should keep it or not, all the mutants I’ve ever had eventually became a pain in the ass. Had to flush - the FFOF was still way too hot, even diluted by a third with Tupur. EC was coming in at 2400, the leaves showed cupping and twisting downwards and some odd burn patterns, so I flushed with distilled water, about 4 gallons total. EC now comes in at 1500-1800 and the leaves are showing to be healthier.
