Suggestions plz....1 week into flowering with minor problems!

Hey guys this is my first crack at an indoor grow, I have 4 Great White plants which I started from seed and grew in MG soil from the beginning and so far so good...almost. Don't really want to ask this question because it seems to be a fairly common topic but I've done my research somewhat and they seem to be experiencing a deficiency of some sort. My water ph is around 6.2-6.5 from the tap and closer to 7 after I mix nutrients in, soil ph is between 6.7-7 and the one plant soil with none of these leaf problems is around 5.7-6. Seem to be affecting the older fan leaves from the bottom up. Using the Floranova series but I have been extremely light on the usage of any thus far. Do I hit them with a good feeding? Been a full week of just water and I tried foliar spraying diluted epsom solution for a few days to see if perhaps that would help, the new growth seems to be thriving well. Any ideas whether feeding more is the thing to do or just keep low doses as I have been? Dont wanna fuck these babies up....critics, suggestions, any input would be cool. Thanks in advance people of RIU.

You are right this does not seem like a MAJOR issue as it is affecting only older fan leaves so far. It could be just a matter of aging and flowering induction. They are not using so much N right now in favor of P and K, which are used in higher quantities in flowering. Inducing the flowering signals the plant that her life cycle is coming to an end. And just like in all of nature she wants to get pregnant. So, most of her energy is being used to develop calyx. At this point I would pull the dead leaves and wait a few days to see if the condition progresses. If it does, repost or do some research on nutrient deficiencies. I am providing a link to some very helpful info. best of Luck!

BTW, Love the Moosehead! LOL!

Thanks for the link, Ive read through it and narrowed it down to a couple of things, suppose Ill pull the yellow shit off and wait it out for a few days as you suggested. Hopefully it doesnt spread as I would like to knock this out while theyre still in early flowering. Cheers! Yeah the Moosehead was a freebie to add to the shop decor, its pretty sweet!

So these are a few more pics on day 21 of flowering, just curious if they're progressing at a somewhat normal rate....any and all comments are wanted and appreciated! Hard to tell for myself because I stare at them daily haha. Gonna start using Monster Bloom in accordance with my feeding schedule, is it true that most plants put on weight in the last couple weeks? Also should I consider lollipopping these or would it fuck them up, they are Great White plants?

I go through the same thing. Always checking on them screaming in my head GROW! I think your plants look good man. All in time. All in time.
