600W LED 1st time Auto grow

The lights were switched on the 17/10 to 20/4 still with blue LED only. I switched the red bloom switch 2 days later and dropped the light to 25" which it has remained at since. TEMPS:22-28c light off/light on. HUMIDITY:40-60% WATER:6.5PH 195ppm WEEK 2 CONT:21/10 I added a small amount of nutrients to my water i added 0.5ml of advanced meta boost and 1ml of organicus99 NPK feed. The reading came out at 195ppm which is well below what was recommended by the manufacturer. i mixed it into 1ltr of water and adjusted the ph to 6.5ph i gave 300ml to the 3 biggest plants i mixed what was left with some more water and gave the smaller plant around 300ml of ph 6.5 adjusted water the ppm on this was less than 100ppm as it was for the runt which was considerably smaller at this stage. Temps are the same at this stage and humidity. i did add some small water bowls which i placed inside the pots under the light to aid with raising humidity. will be feeding again on 24/10 and i will also begin LST during this time. More follow up pictures in the coming days then i will be doing the weekly updates maybe 2 a week start and finish of the week. A QUICK UPDATE: Today 24/10 I stated LST training on the girls. I have also fed them again by mixing just under 1ml organicus99 & just under 0.5ml of meta boost for a ppm of 160ppm i ph'd the water at 6.5ph i gave 300ml to each of the big girls i then mixed the last 100ml to 1lt of ph 6.5 water measuring less than 80ppm and gave a 400ml to the runt and a further 200ml to the rest just to make a good hit into the soil as at this stage root production will be going throght the roof. i watered slightly away from the root stem in order to force the roots and hairs to search out the water. when doing the LST I bent the girls in several directions to see which was the most productive use of the light and managed find where i was happy so tied them to the side of the pots with garden wire and attatched an extra support opposite on the pot. i also removed the first leaves fro the bottom as there is ample groth underneath to pick up the extra light needed to grow. over all i am very pleased with how they are looking. plants ranging from 3-4" at 14 days old
