ok heres the run down.... from SWIM

:wave:

1 Durban Poison plant
5-6 weeks into veg
in foxfarm ocean forrest soil
temps: 74-82F under 1000w MH

watered every 3rd-4th day with 3/4 gal. mixed 3tsp/gal Grow Big from foxfarm
and 1Tbl Big Bloom. fed 2 out of 3 waterings.

SWIM cut off all lateral branches and some small fan leaves underneath the canopy, the plant is trained around a square pot.

ok here is whats happening....

the newer growth of fan leaves by the soon to be colas are drooping downward. im assuming its just stress from clipping too much yesterday, right?

any suggestions would be much appreciated :rasta:

pics would be nice and if you watering with 3/4 gal and using 3tsp thats way to much fert man its only supposed to be 1 tsp/gal. your going to kill them doing that much ferts at once..... you may need to flush and wait or you may have already XXXXXXX

3tsp every other watering for plants in the THIRD week, im in the 5-6th week of veg. do you really think its nute burn? fan leaves arent dead or dry, just droopy and a little lighter green/yellow. only on the plant tops BTW, not under the canopy... ill try to get some pics soon from SWIM

BTW i watered em 2 days ago...

hummmm whats the PH of the water being used FFOF soil fresh out of the bag has enough to fully sustain a plant 2-3 weeks n/p. although i use ferts with MY FFOF soil the 1st watering is allways no ferts and PH'd @ 6.5 the general feeling here on ff ferts. start off 1/2 strength dossage 1st wk each wk bump up the dossage untill full strength is achieved, watch how the plant reacts. i would say @ 3tsp per 3/4 gal water you said ya used, your PH was below 5.8 and for soil thats not good i found anything below 6.0 PH is a no no lol. get yourself a good PH meter if ya plan to grow PH test strips work but the meter is much better. when i used FF ferts i found
1tsp per gal water of grow big drop my water's PH 0.05
1tsp per gal water of tiger bloom done same droped PH 0.05
1tsp per gal water of big bloom did nothing to water's PH
the above test i ran with 1 fert in each gal water then tested the water 1 at a time rinsing the meter off before each test. my water directly from tap is PH 7.2 - 7.3

the big bloom i wouldnt give the plant untill the day of flowering then one time only 1/2 cup per gal water, then every other watering after 2 tblspn per gal water along with any other ferts used. add any ferts used then adjust the water's PH acordinly g/l :rasta:

SWIM was just using tap water, and doesnt have a soil pH meter :( sigh..... but pH is probably the issue.... :( SWIM checked water pH and its around 6.8

take a look at these pics....

the victim



some of the fan leaves






Maj. i hope ur around right now. sounds like you are very familiar with FF. i appreciate the help! :rasta:

merry christmas everybody

fox farm nutes (grow big and tiger bloom) both drop the water ph down A LOT! Before making the switch to fox farm I needed to add 2 or 3 oz of pH down to my 50 gallon res to get the pH to 6.0. Now with fox farm the pH is right ~5.8 after mixing with no pH adjustment.

whoa, ok then its official. pH has to be under 6 then :frown:

should SWIM add the necessary amount of lime to the top of the soil and then water thouroghly ??? SWIM has never done this before.... they are in 3 gal pot BTW

not at all, just keep it around ph 6. also i think your plant would like a good dose of N, your leaves could be alot darker green before tip curling or burn.

Too much ferts

Too much ferts

If your feeding 3 teaspoons 6-4-4 grow big per gallon, your nitrogen would be 236+ ppms. I doubt you would need more than 150 ppm. 150/236 = .63 x 3 = 1.9 teaspoons per gallon. Too much phoshorus can cause problems. It builds up. You should probably exclude big bloom.

Adjust the fert water ph after everything is added to maybe 6. If soil ph is low or high, it will wander slowly up or down toward the fert water ph.

After repeated waterings, dolomite lime begins to run out. Ph will begin to drop. If ph is extremely too low, you can reapply pulverized dol. lime to the pot surface. Try about 1 1/5 to 2 teaspoons per gallon of soil mix. Sprinkle on and water in.

If ph is ok or high, adding lime would not be a good idea. But, your ferts lack alot of calcium and magnesium. You can add calcium and magnesium to your fert water by using about 1/4 teaspoon epsom salts (30ppm mg) and calcium nitrate (60 ppm ca). Calcium chloride sold under names like blossom end rot stopper for tomatoes could also be used instead of calcium nitrate and does not add nitrogen you might not want in flower. It will take the % ca and net weight of the bottle to come up with about 60 ppm ca.

How to test ph: After you have watered and ferted well till runoff, wait 1 hour. Then apply some distilled water to the pot till you get about 1 ounce out the bottom. Catch on a plate or saucer. Test this ph. If you don't have a ph meter to test liquids (buy one!), cheap ph test strips could be used in a pinch.

When watering, make sure you get alot of runoff out the bottom. This prevents salt buildup.

:smoker:

ty blackvelvet for re-aferming what i thought was way to much ferts and it may be locking them out. i would flush wait 3 days and them resume the ferts as directed.

Mr.p and you wont have any issues
