I have upped the feed now to about 1/2 strength and the plants are loving it. They're starting to recover from the low stress training last week and stretching upwards. Budding is underway with white hairs, and a distinctive gassy smell on 3/4 of the plants.
I'm guessing I've got two phenos - 3x Chemdawg dominant and 1x Hindu Kush dominant. We'll find out when they start to flower fully.
Switched to 18/6 from 24/0 on day 36 - now that they're flowering they seem more sensitive to heat from the lights (Also backed the light off a couple inches). This resulted in an immediate growth spurt!
@BudgetFarmsUK, nooooo you can't use CFLs and tomato feed nooooo π they won't flower bro you'll stunt them bro - should have spent Β£300 on gear bro /s
