Not sure if we are having a problem or this is normal. Info first:
1. plants are bagseed (really good though)
2. have been in 12/12 for about 5 weeks, buds are everywhere, some about 3" tall
3. light is 1000 watt hps and is well enough away, never any sign of burn from lights
4. have fed twice with a 11-35-15 and micro nutes (it's actually an orchid fert)
5. plants are in 3 gal pots
6. watering ph is about 6.4 and runff ph is 6.0 or lower
7. temp is about 77 day and 65 night
8. low humidity here this time of year so I mist them, with a fan blowing all the time, no mold problems this way.
I am starting to get some yellow spots on the leaves, more so on the plants with the most buds. One plant is taller and not as bushy, also has the most and biggest buds.
Have some leaves that curl down on the sides and some are crunchy on the ends. The one bucket of water I was using had high nitrogen fert in it ( my partner forgot to dump it and I used it) it's gone now and just watered with straight water.
Have been losing some bottom leaves but not alot (I think it's normal)
What I want to know (have a problem posting pics, will try again) is, is this fairly normal this far into flowering?
The bit of yellowing/curling/crunchy ends didn't start till this week after their second dose of nutes. I also do not use the 1 tsp/gallon the directions say. 1/4 tsp./gal the first time and 1/2 tsp./gal the second.
I also did a little foliar feeding, a VERY small amount of fert in a spray bottle. Only did that twice to try it, probably won't again (may be the reason for this issue)
Like I said, it's primarily the two with the most buds that are doing this (so many I can't count them all

)
Also two real quick questions,
1. how much and when to start the molasses?
2. why are some leaves really dark green and others lighter ( I think these plants are sativa/indica mixed)
Thanks for any help you guys may have and will try to get pics posted.
