Slartibarfast Posted May 31, 2021 Share Posted May 31, 2021 Hi, this is my latest grow of Fastbuds Blue Dream'matic. Growing in coco with the watering being handled by a Blumat. Using FloraCoco nutes. Noticing what looks like calcium/magnesium deficiency on the leaves with some yellowing and brown spots. I am pretty sure the FloraCoco nutes has enough of everything the plant needs so I am worried that it's actually the pH rather. I bought a 3 way soil meter from Hydroponic Shop and it shows my soil pH at just over 7 but the pH of the water in my reservoir with nutes is around 5.8. Any suggestions on what should be done? Also any ideas on getting more light to the lower buds? The plant is about 9 weeks in now. Sent from my SM-N950F using Tapatalk Quote Link to comment Share on other sites More sharing options...
PsyCLown Posted May 31, 2021 Share Posted May 31, 2021 Not sure I would trust that soil PH 3 in 1 meter thingy if you stick it into the coco. You could try adding a bit of calmag to your nute mix if you wanted, otherwise if you are really worried about the ph in the coco then run a few liters of nute feed which is PH'd through the coco - perhaps 6L and let it pour out and this should help "flush" any excess nutes in the coco. So best to do it in a bath tub, shower or outside. As for light penetration, remove some of the lower fan leaves and the dieing ones. 2 Quote Link to comment Share on other sites More sharing options...
Slartibarfast Posted May 31, 2021 Author Share Posted May 31, 2021 Much appreciated, I like the flush idea. Will try it out thanks! The plant is an auto, will it be safe to prune some of the leaves?Sent from my SM-N950F using Tapatalk Quote Link to comment Share on other sites More sharing options...

Take a look at my auto flower grow, I did some serious leaf defol on some of my auto plants and I feel yield has been very good. I got around 100g dry from the LSD-25, have not weighed the others yet and still need to finish trimming them. EDIT: By now your auto has already formed the bud and it's either going to fatten and mature, or perhaps just mature. So I do not see any harm in removing some of the fan leaves, I do it all the time with my photoperiod plants from veg and all the way through the stretch / pre-flowering phase and even in flower and towards the end of flower. 2 Quote Link to comment Share on other sites More sharing options...
Slartibarfast Posted May 31, 2021 Author Share Posted May 31, 2021 Awesome thanks for the advice, will get to it tomorrowSent from my SM-N950F using Tapatalk Quote Link to comment Share on other sites More sharing options...
Slartibarfast Posted June 1, 2021 Author Share Posted June 1, 2021 I am seeing some soil gnats every now and then, could the plant issues be a result of an infestation of them? Really not seeing a lot though, also have a sticky trap setup near the plant.Sent from my SM-N950F using Tapatalk Quote Link to comment Share on other sites More sharing options...
Prom Posted June 1, 2021 Share Posted June 1, 2021 Looks very much like potassium deficiency. Quote Link to comment Share on other sites More sharing options...
Slartibarfast Posted June 13, 2021 Author Share Posted June 13, 2021 Looking better after I switched to full strength nutes. Trichomes are looking mostly clear and cloudy with the odd amber here and there. Any advice on when to flush then harvest? I'm on the 11th week now of this grow, really want some dense buds if possibleSent from my SM-N950F using Tapatalk Quote Link to comment Share on other sites More sharing options...
GGG Posted June 13, 2021 Share Posted June 13, 2021 How dense does it feel now , most probable if you 11th week of flower it won't get much more dense.No need to flush , but you can to ease the mind Sent from my Hisense Infinity H50 using Tapatalk 1 Quote Link to comment Share on other sites More sharing options...
Slartibarfast Posted June 13, 2021 Author Share Posted June 13, 2021 Feeling pretty dense already. Using the trichomes as a guide to harvestSent from my SM-N950F using Tapatalk Quote Link to comment Share on other sites More sharing options...
GGG Posted June 13, 2021 Share Posted June 13, 2021 Patience is the key , I would say another 2 weeks atleastSent from my Hisense Infinity H50 using Tapatalk 1 1 Quote Link to comment Share on other sites More sharing options...
