some kind of lockout

ve got yellowing leaves starting from the older leaves, this is progressive. purple outlines the bigger fan leaves (this appeared but hasn't progressed) and a little white is starting to show on the tips of the newer, lower, smaller, branches. i greatly appreciate any help i can get on my first grow.

specs: 4' flour's x 2, compact flour's x 2 ... "hyponix" potting soil... schultz 17-19-29 tomato food (ive only used once (1/4 strength) and started to burn so discontinued added epsom salt yellowing slowed but then started again)... 7 1/2" 8 nodes 21/3 hrs. 1 1/2 months

thx people

help me out viewers!! plz

hi there do u control ya ph levels at all. and did u say that ya plant is 7 and half inches tall after 1 1/2 mths ?

no i havnt checked ph but ive flushed already once in hopes of fixing the problem just in case it was ph and yes 7 1/2 inches 1 1/2 months 8 nodes workin on 9

you seem surprised at the size... u think its too small?.. i think it was stunted at one point but not for long at all

come on guys... save my girl! (i hope its a girl)

check your waters ph, too high, use ph- and vice versa

if that fails, RO water flush, and stick to RO water for feeding

You gotta monitor pH man. Flushing wouldn't solve anything if the water you put in afterwards has a bad pH. Get a test kit and get back to us.

Check the pH, that is your problem.

Goodluck!

ok , ok , ill get the ph test, i can just flush the pot then test the run off with litmus paper right?

what is the ph of the water you are feeding them with?
