Day 3 of flowering bottom leaves are getting nasty

i have a 400 watt mh inside sun ballast running a 400 watt mh light, havent bought the converter bulb yet... they are in happy frog soil have been in it since transplanting from clones like 2 or 3 months back, i didnt keep track of all the weeks and stuff this is my first grow didnt think of that, they are on a feed feed flush schedule with the pureblend pro botanicare line i am in the transition phase some have gotten both nutes and some will get the bloom nutes as soon as they need water i am also starting hydroplex, and have been giving superthrive every other feeding, i have always had a problem with the bottom leaves before they would get orangeish and curled up and fall off or were very easy to pull off. lack of light? or too much nutes? i recently bought a cfl i just need to go buy the fixture if it is lack of light how much more lights should i get???



these are pictures of 2 of my smaller plants i have 5 plants in total in flowering


thanks

i highly doubt its from lack of light.... 400w mh blows mine out the water. also cut the superthrive cuz it slows down the budding process. besides that i would probably say a toxicity but im not too sure.

all of my plants have problems with their bottom leaves, these 2 have the same colors the other ones just look orangish like the leaves in the fall =/

I'd say back off on the nutes but what do i know? Not much.

trim the bottom third off the plant, all the leafs they arnt gonna produce much bud and itll help air circulation

also instead of the plant putting the energy into the bottom itll put it up into the top
