FastBuds Pineapple Express & Friends

Week 4 was interesting. All 4 girls have seen clear, decent growth however one clearly stands out. PE1 has gone absolutely mental, she's double the size of PE2 and PL1?! PL2 however is still very small but making progress so, I won't give up on her. I switched from Fishmix to Biogrow and added Topmax and Biobloom however, at half doses per litre. Last season my plants got nute burn from the recommened so i'm experimenting, they seem to be responding very well. I also still use a light Fishmix solution as a foliar. I'm watering practically everyday (@ .5ltr) feeding every other as the average day and night temp has risen to 23-25°c and 14-16°c. I'm also now squeezing an additional hour of sunlight. Going into week 5 i'm going to increase the amout of water to about .75ltr and monitor. I may also up the nutes slightly.
