Trainwreck 4 weeks into flower yellowing leafs ?

Hey guys. My ladies are about 4 weeks into 12/12 and some leafs are beginning to yellow, some darkening stems and tiny reddish brow dots on the effected leafs. I am using the lucas formula with floranova bloom. Seeing how hot ffof soil is I have been progressively working my way up to 8ml/gal every third watering. Started 1/4 then 1/2,3/4 was last feed about a week ago. Started using nutes when I switched to flower. Veg clones 1 month. Water ph 6.3 Anyone know what's going on here or is this normal yellowing for week 4 ?

I'm getting ready to take my TW down on Saturday so I may have a little insight on this situation. Mine did the same thing on the 3rd week of 12/12. I gave them one dose of my veg. nutes with nitrogen in it and the stopped fading. I'm not sure what kind of water you are using but I use RO. I have to give CalMag almost every feeding up to the final two weeks.
Just what I did to fix it, you can wait for others to weigh in on your situation before you try it.

Peace

I have been using tap water since day one without a problem. Hopefully the girls are just hungry. They are due for their first full strength feeding of floranova bloom 8ml/gal in two days. Think that will have plenty of N in it to get them back in shape. What day are you harvesting on ?

Nice looking for 4 weeks. Hope you get it worked out. (bumpin you up the list)

The yellowing of leaves is completely normal midway through flowering. Its because the plant is using a lot more energy towards blooming rather than Veg/growing. The brown dots are from phosphorus and magnesium being used more than they were in Veg. Do the same thing Jaz did, It'll fix the problem pretty quickly. If you do add more Veg nutes I suggest a longer flush before harvest.

I fed 8ml per gal flora nova bloom. We will see how it takes. Starting to look almost like a cal/mag issue. Should I need to add cal/mag with tap water ? I know the flora nova bloom has it in it but maybe not enough ?

I may be wrong but it kind of looks like a Fe(iron) def. I thought that a N def. starts toward the bottom and works its way up. I had a Fe def. and it turned my newer leafs yellow and the veins stayed green. I added some Tiger Bloom from FF and it seemed to clear it up. Just a thought. Good Luck Dude

I have an update yellowing seems to have stopped after last feeding but I have what looks now to be a calmg issue? My floranova has cal+mg in it but maybe not enough? Anyone ever experience this? Also now my friend tells me he may have accidentally gave me chocolope clones instead of trainwreck.
