When in doubt flush?

Some leaf tips curling up at the tips and turning brown... lower leafs turning limegreen/yellow..

Im thinking its an N deficiency as far as the yellowing goes, and possilby nute burn for the yellow/brown tips and burn spots.. but I only used half strength.

Im seriously thinking about flushing all 4 plants tonight. Can flushing in flowering do any damage? They are in 4 gallon pots so would I really need 12 gallons of water PER plant to flush each plant??

Also.. after a big heavy flush like im planning... is it best to start nutes back at 1/4th or 1/2 ?

ps: Do I need Tiger Bloom??? Or will I be ok with Bigbloom/growbig

ps:

Ocean Forrest Soil
Strawberry Cough - Feminized
Foxfarm Growbig/Bigbloom
4 gallon pots
400whps cooltube
temps 72-76 at night, and 80-85 during the day.

Where are you in relation to flowering? I looked @ your pics & something is def going on but hard to pin it down. 4 gallon pot, I'd give them 4 gal each of PH'd water only & see how things go. A second mini flush if you see improvement after 5 or 6 days.
I like your set up & temps.

Ending week 4
Hey... man 15 gallons is SOOO much water lol... I think im going to do 6 gallons per pot.

Im PRETTY sure I have a N defieicney going on as well... I might add some fish emulsion as I hear that can boost N...

just some random pics of how far along she is... I feel like the colas could be fatter.. this is my first grow so I could just be over-thinking.. but im hoping they get alot fatter by the end because i do have a really nice setup.

Heres 2 pics i took just now... after reading im thinking I have a Magnesium defieicny ... due to the yellowing/browning

if u look u can see the tips yellowing as well....


and i found this

Nitrogen Deficiencies:
Plants will exhibit lack of vigor, slow growth and will be weak and stunted. Quality and yield will be significantly reduced. Older leaves become yellow (chlorotic) from lack of chlorophyll. Deficient plants will exhibit uniform light green to yellow on older leaves, these leaves may die and drop. Leaf margins will not curled up noticeably. Chlorosis will eventually spread throughout the plant. Stems, petioles and lower leaf surfaces may turn purple.



my stems are really purple......well on my fan leaf stems... how can I fix a nitrogen deficiency??? by adding some FF grow big??? Or what should I add?

??????????

you could give it grow big it has a-lot of N, Also what is you ph at? could need some adj? i like my ph at 6.3

ps: try the FF feeding schedule that will give you a better NPK for you plants

I have come to the realization when ya grow with fox farm products you want to flush at around week three of flower with DOUBLE the amount of gallons on the pot your using.

Also use PH adjusted water too.

The salts build up too quickly and a nice flush midway through flower let's your plant feel refreshed

I would try to use some Epsom salt, grow big , or tiger bloom to correct that def.



Good luck
