What type of medium; soil or hydro? Soil What brand and type of soil? FF ocean forest Indoors or outdoors? Indoors What strain? Barney's Farm LSD How old are the plants? 5 weeks into flower (9 weeks overall) What type of lights and how many watts? 4 26watt CFLs. ~104w How far from the lights? About 1" or so from main colas What is your watering frequency and source of water? It has been about every 3 days now. Using tap water. What, how much and when was it fed? NPK? Fed on wednesday (11/28). Fed it in the morning. Used half the recommended serving of the Fox Farm nutes. I also top dressed my soil with a TSP of Roots Organic : Elemental (dolomite lime) What is the medium/runoff pH and PPM if in hydro? N/A What are the temps and humidity in the room? Temps usually range from 78 (while sleeping) to 86-89 (awake). Humidity is usually quite low.. around 16-24% What size pots? 3gal Any bugs? No Look real close. Any other pertinent info? Leaves are yellowing (but I feel that's normal for being in the 5th week of flowering), tips are really crunchy and making it's way down the leaves. I think I may have used too much of the lime because my a lot of my leaves have all these rust spots on them now. This plant is a hermie. I found a few balls on it a couple weeks back and I have been doing my best to keep it ball free.. So far it looks good in that realm.
dunno about the rust spots (some deficiency Id guess), the leaf tips look like nute burn I believe, but I could well be wrong about that. getting something to test your pH is probably a good idea. those white dots definitly look like bug damage, probably spidermites or thrips. theres probably gonna be some extremely tiny bugs crawling around under the leaves. I wouldnt spray anything on the plant since its well into flowering (otherwise Id use neem oil), so Id either do nothing or get some kind of good bugs to eat the bad ones. from what Ive read ladybugs also eat mites (although they specialize in aphids) and there are a few species of predator mites that specifically feed on spidermites.

It actually looks rusty brown
