On the bottles of fox farm the doseage is much higher big bloom calls for a 1/2cup per gal ect

I am using the same ff trio and I have never used that much in 1gal.as far as the light distences manufacturers directions should tell u looks a bit to close to me.Temp. Is good lol

 

[steve]

looks like a bit of heat issues - tips are brown -

 

[Flockshot]

Perhaps both.

I go by the same schedule, but I use 1/2 of what the list calls for.

(half a cup?) I GUESS I HAVE BEEN DOING IT ALL WRONG! I use the same trio myself. My dosage is far lower then yours. I mix 3 tee spoons per gal.

So how much does everyone use of ff??? The temp is 72-79 do u guys really think the temp is to high? Can anyone tell me a straight answer of why they think the tips are curling down?

 

[tyler_ hobbyist]

And why they are doing that? And how to fix it?

Is it an auto flowering strain?

 

[tyler_ hobbyist]

Yes autoflower blueberry week 9

This is my take on your grow:
LEDs will often cause the tips of the leaves closest to the light to turn brown on the ends.
while the 33% rh is fine, it may cause the plant to transpire more and take up more nutrients as a result.
your temps are fine for this stage of flowering.
I do not use the same nutrients, but will offer that you should adjust the nutrients to the amount of lights- as the manufacturer bases the amount on 1000 watt light/ plants
And most auto seed banks suggest 1/2 nutrient levels for auto's.
is your LED is in the correct range for flowering- most are 12-18" in flower and your plant will club at the bud if it's too much.

dont do anything drastic, you will make it to harvest.
I would cut back or stop Nutrients and wait a few days, then adjust the LED to the plants liking.
The remaining fan leaves will start to turn yellow, from the bottom up which is perfectly normal.

Thank u very much weedpharma I really do appricate your guidence and time. I moved the lights from 18inchs the 3 flowering plants and the others are 24 inchs away I'm gunna cut back on the nutes, my next watering I'm just gunna flush with ph water then I was thinking for nutes 1tbsp bigbloom and 1tsp tigerbloom per gal should I add 1tsp mollases? As well or just wait a couple more weeks or use the mollases just to flush? The rh I can't controll at the moment funds are tight right now. How does my game plan sound?

 

[Weed Pharma]

I would let it dry out and resume watering with molasses for the remaining time. This will effectively use up the nutrients in the soil for the last couple of weeks.

the rh is fine.

the less you do here the better off you will be -IMO

72-79 is just dandy for room temperature. That may, or may not, reflect the temperature hitting the leaves.
There is no one straight answer to the leaf curling down since many things can make that happen. However the most common reason that I can think of is heat stress. Now, only you know if you are over heating your plant by having the light too close. If not, then eliminate that as a possible cause and go on to other possibilities.

Thank u flockshot I moved my lights further away

 

[tyler_ hobbyist]

Thank u everyone for ur help it's greatly appricated

 

[tyler_ hobbyist]

I thought I would just update everyone I moved my lights 18-24inchs away and watered the pH water the problem has seemed to mainly go away only 2 or 3 leaves are still curled down but not as bad as before
