Help! Still have some sort of deficiency in the fourth week of flowering!

I still have some sort of deficiency but I cant figure it out. The leaves have reddish brown spots with some yellowing on them. The leaves get brown dark and crunchy towards the ends. The reddish spots seem to be spreading and the yellowing seems to be increasing.

Any info would be appreciated
thanks.

1. First time time grower

2. Bag seeds

3.Plant specs: Its around 4 months old and 42 inches tall an 39 inches wide.

4. 17 gallon pot

5. 18 cfls @ 23 watts each (actual wattage) = 414 watts + 8 T8 Florescent tubes @ 32 watts each (Actual wattage) = 256 watts for a total of 256+414= 670 total watts. They are on a 12 - 12 cycle

6. Fox's farm soil

7. Nutes: Big grow, Tiger bloom, Molasses, Epsom salt (for magnesium)

8. I alternate between feedings with tiger bloom and big grow for one feeding, then the next feeding is molasses and Epsom salt. Then I repeat. NOTE: I have only used the Epsom salt twice up to this point. I was using half the recommended dose, I saw a little burn on the tips so I reduced it to a quarter of the recommended dose.

9. I had some ph issues in the beginning but now its between 6.5 and 6.8

1o.temps range from 72- 80 degrees

11. Ventilation is very good.​

how long ago did you have the ph issues? FF nutes WILL burn the piss out of your plants and salt buildup is a problem! I would foliar feed w/epsom only and flush the soil out. Most people will tell you not to give the full dose according to the feeding chart with Fox Farms. cut it in 1/2 and you will be better off. You said it's a 17 gallon pot... That is a big frigin pot man. My guess it's buildup of all those nutes your adding making your soil a little "HOT" and it's not easy properly flushing a 17 gallon pot.

Thanks for the advice guys. I just watered it last night and it usually takes about 5 days to dry out should i wait until the next watering to flush it?
