Yeah I use Cal mag and their silica additive.. Have back off the Cal mag a bit since started flowering. I was considering flushing but how bad will that mess up my flowering?Maybe N tox, do you use cal mag? Try flushing with cal mag suppliment and a teaspoon of unsulphered molasses. By flush I mean water them with the recommended amount of molasses and calmag supliment in your water and water them until there is heavy runoff, usually about twice as much water as normal to flush. Calmag will take care of most minor difficencies and the molasses helps rinse the salts from the soil. Unsilphered molasses only
I've been following the gh online feeding chart to a t..a little extra for my widows cus they seem to be nute whores and had def problems till I ramped them up a bit..my first thought was N but am feeding what gh recommends..BTW Ive used promix for nearly a decade now. what are your dosages on 3 part per gallon? and clearly not N toxicity but N deficiency. they are cannibilizing the fan leaves for nitrogen
They are 7 gals and water about three times a week, about half gal per a wateringdrying out too much, give a nice clean watering once a week with 10% run off. if those are 5 gallon pots I would water around 3/4 to 1 gallon at a time. 3 times a week
I'm pretty sure there almost completely dry before I water..I alwàys wait till there very light when I pick them up...I've read you want to let them dry up pretty good before you water..you think i should water before that?how much extra N would you add to fix the N def? Watering might be twice a week..every three or four days has been the usualthought you said dry out completely before watering?
I would say drop your pH a little to 5.8 along with giving the increased Calcium/Magnesium/Iron. For good measure I would flush them to 200ppm or so before feeding the new mixture. If everything has been going alright and all of the sudden this has happened, it could be because of a few things:
The plant has been switched over to flowering for two weeks. it has come out of transition lag period and is now consuming the food it was leaving alone during the transition. Because it is building flower mass it has consumed the fertilizer and has moved on to sugar in the older leaves, turning them chlorotic.
Otherwise, you may have some bugs or fungus/bacteria.
I feel it has just come out of transition and you need to increase your Ca Mg Fe and even a little bump of N. Stop using Silica now because it can induce the formation of some seeds. 1tsp/gal of molasses until your plants are dark hunter green then back off.
Happy gardening![/QUOTE ]
I'm positive there is no bugs\ fungus etc. So your saying feed more Cal mag and a bit of N..as far as molasses should I use something like hibrix or will regular house hold stuff work the same? Also yes I've been reading more and more that a soilless mix like promix should be around the5.8 mark..but I've been trying to avoid using ph up and down cus my nute mix comes out at like 6.3 after I mix it..
Not sure what to think of this..week two of flower..growing in promix bx, feeding full gh line..lots of yellowing on lower leaves and middle of plant..tops look fine..ph is around 6.3..completely letting dry out between waterings..im ripping my hair out hereView attachment 3540655View attachment 3540657 View attachment 3540659 View attachment 3540660
10-4 thanks...you wouldn't add any though?molasses is cal mag and sugars. hi brix or blackstrap is fine.
Do you use ph up and down with promix?BTW Ive used promix for nearly a decade now. what are your dosages on 3 part per gallon? and clearly not N toxicity but N deficiency. they are cannibilizing the fan leaves for nitrogen
