Purple Wreck yellow leaves

As you can see, the leaves are going yellow from the bottom up. Im currently feeding her 2.5ml per liter bio-bloom and bio-grow, and 1ml top max. Should i increase any of the nutes?

Sorry, its around 3 weeks flowering!

yellowing means lack of nitrogen do to not enough nitrogen in the feeding,or nutes look out ,or end of there life cycle to me they dont look ready for harvest so if you fell they are getting proper nutes then flush them with just water to clear out the salt build up and when need water again go back to nutes

you just finish the stretch, fist 2-3 weeks of flowering, where it is big and grow the most and therefor also use the most, learn from it for next time, once you flip to 12/12 you hit em hard and get some grow out of em, not much to do now, as they are done, no more or only very little Nitrogen is needed from now on, now it will need more P and some K

but not to worry, it don't look that bad and only thing the plant have done is "steal" some food from the lower/older grow

imo you will be fine. Will loss some yield. the cause would be hard to figure with little info. on the grow. Id say most of this would most likely be from bloom boosters or over nut. in nit. When people hit em up hard with nuts in early flower all the main leave die. The real key is steady low nuts. to keep em green all the way thru. Most newbes over nut. Slow and steady is another key to max. The last month or so MAY be a time to take some bid leave out if the lower buds dont get light. rather then taking big leaves better yet use string to move em slightly for better light to lower branchs and/or just move big leaves behind branches to better light to lower buds. good luck yo u will be happy...

I lollipoped her shortly before the yellowing, but havn't had problems lollipopping before! im sure she will be fine, and i keep up my 5+ oz per plant!
