spotty issue 4 weeks in flower....

[captinknots]

hey guys. just noticed this pop up over the last couple days. its only near the middle of the plant. the outer tips of the leaves are developing yellow spots.

any ideas?

the soil has everything in it. its ffof,perlite,ewc,blood and bone meal, 4-4-4 all purpose,greensand,dolomite lime,kelp meal.

ive only given em water. new to this kind of growing and totally blew it my first try. trying to avoid those results this time. thinking about just giving them an ewc tea just simple style. ewc and molasses bubbled for a day. i just watered a day ago so it will be a week before they get any a dose of anything.....

fill out that form man
and take pics with orange hps lights off.
Can't see the problem u talking about with these pics

 

[kerlito]

for me look like one i has before

if you cant tell by the pic, they are yellow spots showing up in the middle of my leaves around the middle of the plant.

temps are 75 when the lights are on. conditions are all in check! perfect! soil is super soil, which ive had some terrible results with, these are the best looking plants ive ever grown in this soil mix (Rev's mix from skunk mag) i dont think 2 weeks was long enough to cook this soil but thats another tread....

what would cause yellow blotches on green leaves half way down the plant? 4 weeks into flower?

tell me temp in all day , when light is on and when light is off

becose i was same problem this winter

 

[captinknots]

i dont go in with the lights off. my lights are off during the day time hours, so its actully a few degrees warmer at night (which is during the day) i can here the exhaust fan turn on and it turnes on at 80.

I'm only guessing but I presume when you say 75 at lights on, thats the relative temp. Its always really important to know the temps at pot level especially at lights out in the cooler months. You'll be surprised at what can be a big difference between the two and rootballs dont want being below 18 degrees. Any lower and phosphorus will start to slow in the plant

75 degrees at lights on is about right but any cooler is too cold. I would also be concerned about my lights off temps being higher than my lights on temps

 

[kerlito]

i think the same of jolee

only i hard to explain for me

 

[captinknots]

thanks ya'll.

the temps are 75 on the plants. my thermometer hangs from the light hood over the plants. the temp on the plants in 75 the room is 71 to 72

brewing a tea now of just ewc and molasses. they should be thirsty in the next day or two, but the problems getting worse by the day!

u have to flush , with out nutes , and right ph

 

[captinknots]

why flush? how is that the answer? ive only fed them water there entire lives. the soil has dolomite lime to buffer ph.

what do you think is going on?
