First-Ever Indoor Autoflower Grow

It is day 60 from sprout for all four plants as of today (6/21/2017). Critical Jack's leaves started to get a pale, sickly, yellow color to them over the past few days. The weird thing I noticed was that the Critical Jack has lower bud sites and weaker branches who look very much green and alive whereas the leaves around the larger bud sites look like they're about to die off. I have also noticed similar coloration developing on the Industrial Plant over the last couple days. I am not sure what this could be since it really only seems to be effecting Critical Jack and Industrial Plant. Maybe the 2 Dinafem plants are sensitive to losing the Root Igniter & Root Tonic supplements from the Elite nutrients schedule. White Widow seems to have stopped growing upwards and she is my tallest girl at 31". She seems to be on a slower pace through this part of the flowering stage but she is no longer temperamental when it comes to the changes in humidity and temperature. Speaking of which, summer has kicked off here and temperatures have stabilized with relatively high heat and humidity now. I turned off the heater in the tent over the last week because it's warmer in the space where my tent is located. Ripley's OG just has fat frosty nuggets all over the place that smell like fruit salad! I am itching to try her when she's all finished -- sadly, it's gonna be a little while longer. She is starting to show some slivers of red and purple on her sugar leaves and buds as of Day 60. I have looked at the trichomes from all of the plants with both a 60x loupe and a 100x optical microscope and I have not seen any amber yet. Critical Jack seems to be the closest to being done -- her trichomes all seem to be milky.
