Hello,
I'm using some "bag seeds" for my first grow, so not sure what strain(s). I have 3 plants (one died early). The plants have been "above ground" for 18 days. This is an indoor grow with 1 4ft 54watt T5 flouro and 2 4ft 32watt T8 flouros (6500kelvin/2700lumens ea.). I'm growing them in a closet (approx.) 5.5'X2'X7'. Using a ~3:1 perlite:vermiculite mix, started in rockwool starter cubes currently placed in 4" pots. I'm hand-watering them w/ General Hydroponics Flora/Grow/Bloom nutrients. Started them off with very low strength, and have brought them up to about 1/2 strength (per mixing directions). I did use a small amount of baking soda (~1/4 tsp) to try to raise the pH, but had to use some lime juice to lower it again (yes, I have mixed a new batch for the next watering) but am planning to flush them with plain water today. I don't have a good idea of temp/RH (first grow, SMALL budget). The pH of the last nutrient solution they got was ~6.1-6.4. There were in the basement @ first, but after seeing some spider webs they've moved to another closet which seems to be pest free. I'm only watering about twice/week (when the medium starts to dry out about an inch down). They did stretch a bit as I kept them under a plastic hood a little too long after they sprouted, which limited how close the light was, but seem to be doing much better now. I think the problem could be a potassium deficiency (possibly caused by the baking soda used to raise the pH), which is why I plan to flush them today rather than give them their normal nutrients, but I'm concerned it may also be a nitrogen deficiency, phosphorus deficiency, magnesium deficiency, calcium deficiency or possibly just too high pH. Any second/better opinions are much appreciated. I'm not stressing too much, as this is sort of a trial/experiment run, but I'd like to see my first grow go well if possible. Thank you in advance!

. The nutes are General Hydroponics Flora series (grow-micro-bloom) that I've been planning to use according to the labels (like I said, half strength so far), but after today I've been considering Lucas Formula (though I haven't found much info to indicate whether it's any good for the hand-watering method). They were due for a watering today, but I just flushed them with some plain-old-water.
