2nd grow of GDP autos in a 4x4 tent.
General Hydro Nute water in aerated buckets. Only one plant went to bloom.
It is covered with Small nugs but no sticky trichomes. Other 3 plants haven’t even started to bloom. We are 7 weeks in.
They were starved of water and nutes on week 4 due to unforeseen circumstances. Roots didn’t completely dry out and plants looked like they recovered after some trimming and re-doing their nute water. Plants “look” healthy but no sign of blooming on 3 and no trichome development on the 1 that is blooming.
Last grow had almost a lb of nice sticky buds (with great characteristics) from 4 plants. Did I ruin them due to the water issue or could the seeds be wrong.
3 look like normal photo plants that just haven’t gone to bloom yet.
Autos are like a box of chocolates, ya never know what cha gonna get..more than likely your watering issue couldve stunted your plants a bit. Autos will flower when they are ready. If you get too concerned with time, then flip to 12/12 like you would a photo and see if you can force them to flower.
Running 12/12 on 2 indoors. I have 2 outdoors as well. They are way behind. The 2 indoors look like different plants. One stubby with trichs, the other is spidly and no trichs yet. All 4 are PKA.
Congrats to you ! Awesome setup 
Gonna chime in an say I had an auto start flowering and a watering issue happened and caused a 2-3 week setback on flowering, she bushed up and like went back to veg but kept the pistols and then hit like a truck when she decided to push flower I kept feeding flower nutrients.
Keep conditions favorable and proper feeding drench to drought and she will stack for you.
