Never grew Cherry Bombs,, but here is a Cindy 99 ready for chop tomorrow. I'll get to that in a moment.
Only talking veg here....
Lights - 18 / 6, 250w MH, Fans on timer and do not run when lights are off. Temp pretty constant 70 / 74F.
Maybe you are, but if not... you may find it beneficial to run your lights during the colder period. Perhaps lights off from Noon until 4:00 pm? While I believe plants should have a "rest period",, still... maybe go 22 / 2 for the heat in veg if needed?
Water / nutes- I'll load up the nutes until I start to see tip burn,, then back off about 15%. In veg they take very little water even with my low, low, low humidity. In 3 gal. pots they may go through a 1/2 gal. watering every week to 10 days. I judge by the pot feel (weight) as to when and how much. Given your situation,, I'd probsably seriously consider adding 1/3 cup of 3% peroxide per gal. to insure oxygen at the roots. I'd certainly would flush just for a re-start to be confident I'm not loaded with salts at this point too.
Veg / flower- I like to match my veg times with flower times per strain. Just seems to work well for me in my environment. Genrally my Cindys go 6 to 8 weeks veg and after put to the screen they'll average 28 to 30 inch tall and spread to about 24 inch wide on the screen when added. I'll start training early in veg.
I keep pretty good logs on all my plants.
Here's the full "take" on the one showing.
VEG - 7 1/2 weeks, 250W MH, 18 / 6, 3 gal. pot after seedling, Jack's Chemical nutes, Pro-Tek, Cal-Mag, Soilless mix of 2 parts Pro-Mix & 1 part small Grow Stone. with 2 Tbs. Dolomite at start. I position the light (horizontal on veg) to control stretch the way I want it to finish. Training starts as soon as practical per growth. Temps constant at 70-74F.
FLOWER - 7 weeks from flip, 1K HPS 14 to 24 inch from plant. Grown V-SCROG style with bulb placement 1/3 below tip of top cola per plant height. Generally water / nute 1/2 gal. every 2 days. Nutes are substantially increased (3-4 times recommended). Water for run-off. Bloom boost added once every 2 weeks. Temps with light mid 80F, light off mid to upper 60's. 12 / 12.
Typically, I'll fill my screen and may over run a little. Generally plants are about 40" high by 30 inch wide at harvest. Typically I'll harvest 5-6 oz per plant. While not any earth shattering harvest,, it's simple, easy, and predictably consistent. Since I'm running perpetual,,, I'll harvest one every 2 weeks give or take a little. This one may be a bit light in the bud dept. as I was trying a new POS bulb that I've since tossed to the dogs.
It's difficult to stay within my state's "Legal Medical Limits". It would be so easy to over do. There are potentials for doing way better if I wasn't so concerned with "being within limits".
Hope something in there will be of help for you. Good luck & cheers.
