Skinny Pot/Weed?

I will be adding Maxibloom with Maxigrow for the second week of flowering. Durban Poison is growing like a weed. I hope I can hold off defoliating until the end of week 3 in flower. OK I added the maxi bloom and maxi grow half strength each , along with all the other goodies on the list. I'm keeping the tds around 700 because it's been working. One week of flowering done , nine to go. I plan to follow Growweedeasy Nebula's 3 step defoliation. Growing very wide , it could be the side lighting. My side lights are blurple and my top light is 3500k white. Looking at the plant today I can finally notice a vertical stretch going on. Durban poison is growing into it's leaves. This is a strong healthy plant. Mixing MaxIgrow and Maxibloom equates to 7.5-10-14 which seems to make sense during this 3 week flowering stretch period. I will report plant size numbers tomorrow the end of week 2.
