help noob is it lockout or does she need nutes???

so this is what i did. I grew her in peat moss till the lil leaves at the bottom started to turn yellow then i put her in ff soil and she blew up from 4'' or 5'' to a foot in 2 weeks or so then i changed the lights over to red and 12/12 ( 6 65w cfl 9600 somethin lumens)
and its been right about 3 weeks and she started to yellow again so i put some ff tiger bloom in some distilled water ( i always use distilled) then i had to bring the pH back up to 6.0 so i put a very tiny amount of baking soda and i don't know if that is effecting her i only water her with that once so far the yellowing persists i also had regular distilled water that i pH to 6.0 with some ph down from petco that i used in my dwc its supose to be sulfuric acid thats what i water her with regularly. thanks in advance for your help Ive been trying real hard to keep her healthy and happy


p.s. sorry for any bad grammer and spelling ( o and i do have a pH meter wasn't guessing though that might b important)

try and aim for 6.5ph
whats the NPK of ur nutes, because it does look like N def, but also a hint of burn
so if ur nutes have a decent amount of N its lock out u have to measure the run off PH not just Wat u water her

tiger bloom is a flowering nute, witch has a low N concentration. but it does look like a bit or burn. i think you may b giving her to much P-K and not enough N. you will see some yellowing on bottom leaves throughout flowering, just usually not till week 5-6.

are you seeing redish purple stems on the fan leaves? it possible could be a slight N, and cal-mag defficiency

Really the way I see it your waisting your time messing w the Ph if your n soil I don't give a shit what anyone says I've got ten plus years of soil grows under me n never once checked my Ph my hydro grows r a dif story that said... you are using weak light so mix your nutes at half n go up from there if u have to but start with a good flush. Feel free to Rep me if this helped

so i should lay off the tiger bloom and mix some grow big at half and give her that for the n def and test the run off i guess you compare and at next water bring the pH higher or lower to compensate or to balance

yea id give a small dose of grow big/tiger. but flush her first. i really dont ever check PH for my soil plants either. it shouldnt be outta wack unless ur using some gross water... haha

Happy 4th she got better then got worse and its been up and down but recently I got some flora klean that seemed to help I also got a 400w hps she liked the buds look fantastic very frosty and they smell like fruitloops so I'm going to keep tryin I think she has 3 or so weeks left I'm looking forward to harvest thanks guys for your help
