i am really excited since this is my first grow. i ran into a few problems with my dwc set up early on but i think i corrected all the issues i had. i still have a few questions i cant seem to find easy. sorry about grammar my caps and symbols dont work for some reason when i use my phone on forums i want to go into flowering 5 weeks from planting the seeds. has anyone done this and what issues could i run into/ i am doing a transition into flowering schedule but to get the 12/12 cycle how i want it i needed to extend my days during the transition. is 8/18-10/18-10/18-12/16-12/16-12/14 and then finally 12/12 there on. will i face any problems transitioning like this or is this ok/ how do you guys switch to flowering nutes/ i was planning to clean res and add flowering nutes the day the transition is complete. can adding a frozen 2 liter bottle of ice to my res tanks harm the plants/ i have two 30 gal res tanks and the only way i can seem to keep temps below 70 is using frozen 2 liter bottles. i just worry i may affect the roots if the bottle rest too long on them. is it normal for plants in veg to grow outward a lot more than upward/ for example my biggest plant is 5 inches tall and about 13 inches wide. ok well thanks for any input. i will keep doing research but any advice or input is appreciated. this is my first grow and i researched a year before i even tried and i still feel like i got tons to learn to get though this grow.
