thanks for the info both, i tried getting epsom salts today but i only got as far as going to the post office before i had to stop, so ill try and get some tomorrow, i think epsom salts will help or solve the problem if i can get some, its def a lockout of some kind but not sure if its ph or due to to much nutrients, i know its not the molasses as they have all only got 1 tea spoon per gallon so cant be nothing to do with that.
reps to you all for helping,
so with the soil plants anything from 1 table spoon upwards is good, 2 is ok and 3 if the plants are really hungry, this plant was really hungry and was drinking lots compared to the other plants, but i water until i get a small amount of run off so it sits in the dish then gets soaked back up by the soil then i empty the dish so the pot can drain if needed, but this plant was in a black pot that had small drain holes and not enough of them, so when i flushed i notice very little was coming out, so i poked several more bigger holes and drainage was vastly improved, so im thiking the nutrients have not been able to drain away and its just built up in the bottom of the pot and its thrown the ph off or to much nutrients at that level, i think if the whole pot was affected then the clone thats been rooted for a good week now would also be having problems but that just looks totally fine, i had to flush due to how quick the leaves went bad over night.
im going to have to get a soil ph test kit, i dont think testing the run off is very accurate at all, i could use a bit of soil and shake it up in a tab with water then filter the soil out using coffee filter then i can test the water, but not sure if that will give me an accurate reading or not, i could ph the tap water before the mix then ph the filtered water after but im not sure if the ph works by doing it that way, i could do with checking the ph in all the pots so i can get things dialed in to perfection, ive not had any problems till now so not needed to do anything to the soil plants, i dont even check the ph in the dwc as the plants do great in that, so ill save up some pennies and get myself a soil ph test kit and also a ppm meter, its times like this when i could do with them, it just shows that you do need them at some point,
so i think miwa is spot on, nute lockout caused by either ph issues or salts building up at the roots, i did think cal/mag def but i upped the nutrient to give higher P and K and also fed it twice with molasses but i thought that had solved the problem as it had stopped getting worse so all day yesterday it was stable but over night and this morning other leaves turned yellow and some totally turned crispy and fell off when touched, so its gotten worse pretty quick which points me towards a lockout or to much nutrients again causing a lock out,
so flushing will now give me a fresh start, ive not added nutrients yet so i can see what happens over the next 24 hours, it wont affect flowering if it dont get nutrients for a couple of days as its got 5 plus weeks left in flower so a few days with no nutrients is not going to hurt it, ill see how its looking tomorrow when i get up, i just want to let the soil dry out a bit and see if the problem stops or gets worse in the next 24 to 36 hours, then ill add nutrients and molasses, ill start with a weak feed than add molasses or just even add molasses and no nutrients for the next feed and see how it recovers, its going to get worse for at least 24 hours until the roots get oxygen and the plant has used up everything in the soil, so the next 36 hours should give me some idea of whats going on.
its just strange that it has only affected leaves on one side of the plant, the other side is not affected and leaves look perfect, the leaves on the affected side are only showing problems on the fan leaves on the inside of the branch, the outside leaves are totally fine, this is what makes me think the problem is lower down in the soil as the roots higher up must be doing ok and getting what they need, N is fine as leaves are a nice shade of green so i think the problem is all down to the drain holes getting blocked, plus in this pot i dont have any pumice stones in the bottom, so i think the issue is the bottom of the pot so now ive poked new holes and bigger holes that should of solved that problem.
it just wish i had a way of checking the ph, i cant do nothing now till the light comes back on but if their was a decent way to test the ph with the pen i already got then that would save me spending money i dont have on more equipment, im going to get an ec or ppm tester so i can push the dwc cuz when this sensi star is harvested im planting my next auto in the dwc so i can see how they repond to that.
so for molasses
2 table spoon max or 3 if plant is very hungry and can take it,
so the dwc is best to foliar feed, i have put some in the res when i last did a res change but i was only using 1 tea spoon per gallon as i was using the wrong measure, so it only got 1 tsp, its just some growers so its ok to use in dwc and others say it can cause root problems if the bad microbes take over the beneficial, would i foliar feed just the fan leaves as wouldnt want molasses on the buds, not that its got any fan leaves cuz she is pretty naked at the minute,
ill use 1 tsp per gallon for the dwc and see how it goes, its nearly at harvest so its not going to affect it much but at least i can monitor the roots for a few days before it gets flushed and plain water for 24 to 48 hours then ill pull it down, if i dont see any root problems or slime build up then ill use molasses but at a lower dose unless anyone can advise if its safe for a dwc or not
so i got the soil amounts sorted,
dwc ill hang back and just feed 1 tsp per gallon until harvest so i can see what happens, if their are no issues i may up the dose when my next dwc is in flower, but ill see what others say.
now all i need to know is how early would you start feeding molasses, its just ive never used it before until miwa suggested i give it a try to bulk up the flowering buds, i know a lot of growers use it so after miwa suggested it i thought id go out and pick some up, again ive read mixed msgs about when to start using it, some growers use it in early veg and just up the dose for flower, others only use it in the last 3 weeks of flower and the rest anything from 4 weeks before harvest and as little as 1 week before harvest,
so its best to flush after using molasses, so flush a week before harvest, ive not bothered flushing as its not needed with --- so i never flushed at all, i have how ever just stopped using nutrients for the last week to 10 days so i know the plant has used everything up but organic nutrients are suppose to be ok and a flush is not needed, but flushing is not a problem.
so now i just need to know how often to feed molasses, is it every watering, or every other 2 or 3, then how early is it best to start, can molasses be used from day 1 at every 3 to 4 weeks until the plant is in flower, or can it be used more often or is it best not to use it at all in veg,
thanks everyone
