Karels Haze & MAC in 40x40 FIRST GROW

sativa_small_tent Hi guys, this is my first Grow. I have three Karels Haze from SSSC and a MAC (top left) in the tent. I bought all four of them as young plants a week ago (they were about 22cm tall) and sent them straight into flowering. Now on the 7th day of flowering they are about 28cm tall. Unfortunately, I messed up a bit when repotting them in fabric pots and they are now in about 1.4 litres of BioBizz Light Mix. My lamp (Viparspectra P600) has a maximum output of 100W, it is currently dimmed to 65% (i.e. about 65W) on 40x40cm and is 60cm away from the plants. Is that too little or too much? I plan to make the lamp more powerful over the next few weeks. I have BioBizz Bloom and BioBizz Top Max.

sativa_small_tent Hey, they are not stretching that hard. At day 8 of flowering I fertilised them for the first time, I mixed 1ml Bloom and 1ml Top Max to 1.2l, each plant got about 300ml of this water. Is that too much? How often should I fertilise them? Rather more as they are in such small pots? I would appreciate any tips ? Are they not stretching that much because of the small pots ?

sativa_small_tent At Day 15 i gave them each 300ml with fertilizer. On 1,2L 1,4ml BioBloom and 0,8ml TopMax that is 70% of the recommended quantity.
