XanHalen OCT 8th My first run with some decent genes, very new at organic growing, I have 4 Sherbet autos currently in flower who are all organic but only top-dress. These girls are in pre-amended soil, seeds planted in a pocket of non amended media, so after 7-10 days the roots should start hitting the amended media. Using dechlorinated tap water pH'ed to 6.5 - 7. Amending with Gaia Green 444 + 284, Worm castings, Dolomitic Lime, Bokashi compost, and once roots are established I'm adding liquid weight every few waterings. Paper Towel germination took 4 days, no Glass Of Water method used. The freebie was X2 (Mephisto's Wedding X Grape Walker Kush), Will be running them outside next summer.

XanHalen Oct 10th Soil is pre-amended, good till start of flower... One girl only has one cotyledon, all 5 seeds popped and broke soil... I have to cull one girl before they move to flower tent as I have one pot with 2 seedlings in it, may the best prevail... Domes are off, PPFD at 90-110.

XanHalen Oct 16th #1 has weird brown necrotic leaf patches but is keeping up.. #2 doing very well but has very minor necrotic patches.. #3 has warped and thin leaves that look almost crusty, I think the pocked of non-amended soil she was planted in wasn’t big enough or sumthin, prolly hit nutes too early.. #4 is perfect… textbook perfection… #5 is growing well but is mutated, looks interesting though, this is the girl that sprouted with only one cotyledon… Watered today at 6.5 pH and 2 tbsp of worm-castings/L; about 150-200 mL of total input/plant. ✌️

XanHalen Oct 25 #2 started presenting the whorled phyllotaxy trait, but the newest node is not displaying this, another was not presenting this early, but its newest node is confirming it too carries the recessive gene. #4 currently looks the most promising. Clipped the newest fan leaf set for lightypoo. Still no sign of flower yet, which I like, may just have some not so miniature mango runtz

XanHalen Nov 2 I found a crab spider on one of the Baby girls, scared the shit out of me, but I’m leaving him there to fend off any pests. One of the mango runtz Hermied, it was pulled and tossed. Been almost 30 days since last amendment and they just entered flower so I I top dressed bloom at 1 tablespoon per gallon and grow at half a tablespoon per gallon, 1 tablespoon per pot of bokashi bran, then about 3/4 a cup of worm castings on top and watered in with liquid weight at one ML per litre. They should be good till end now. Gg for now growmes

XanHalen Nov 12th Everything going very well, plants are much bigger than expected; then again I seem to be the only one growing this strain and actually shaping the canopy flat. Eugene Crabs is still acting predator for this grow space, no signs of pest transfer from the other tent. LW @ 1mL/L every other water. VS 1500xs at 15in from canopy @ 75%

XanHalen Nov 21 I have eased up on the LST, I'm happy with their shape so just minor defoliation till finish. one in the back looks a bit rusty=calcium deficiency in most cases so I gave calmag @ 1mL/L, along with he liquid weight almost every watering. Been keeping on track with not letting the medium dry-back fully, about 1L per day keeps things moist. Next watering I am topdressing 2-4-8 @ 1tbsp/gal with a sprinkle of bokashi bran and watered in with LW, This will be the final top-dressing. Looking very good, one girl is very purple early on, I haven't experienced genetic colour expression so early in flower thus far, very cool! It seems that Mephisto Genes is gonna be a staple in my tents for a while if an intermediate strain is this easy to grow!

Grow Questions
XanHalen
XanHalenstarted grow question 3d ago
What really causes this rustyness to slowly creep and cover the whole plant sometimes, and sometimes plant only partially affected, always in midflower. I know the obvious answer being calcium/mag but even with increase in this there is oftn no change or noticeable slow in spread

calcium and magnesium are two different things. I do not see a magnesium deficiency symptom. The spots could be related to a Ca deficiency. So, if you also increase Mg, this may be exacerbating the problem. Leaf symptoms are not discrete. Definitely have some dark green foliage with a lottle glossiness, which points to a N toxicity. Too much Mg or Ca can cause dark green foliage too. Heck, you could even be locking out K. N, Ca and Mg at high levels can fuck with K availability. So, if you choose a path, let's say dumping more Ca into it, and it gets worse, you should revert and consider another path. If systematic about it, you should figure it out over the course of a grow or 3 depending on luck with your initial guess. If you change soils or constitute it differently, you will have to go through that learning curve again. It's tough to say anything specific with soil. There are unknowns, like what is the medium providing and what are you supplementing? frequency of frtilization is only a problem if feeding at too high of a concentration relative to frequency. If this weren't true, then every single soilless grow would be a failure and hydroponics wouldn't work. No matter what method, they work best when it results in a proper ratio and concentration of nutes being plant-avaaible around the roots. If sticking to good watering practices, this shouldn't be a problem -- fully saturate, wait for dryback, repeat. Don't overthink it

Hello mate, i had many times this problem and the solution appeared when i check the equilibrium of Ca and Mg in the water that i used for watering. At the time you have an imbalance in this rate you will have different type of issue hardly to link to that. Your condition is one of that so i advice to check your rate of Ca/Mg in your water and fix it (3:1 or 4:1). Good luck and happy journey!!

Yes, some calcium deficiency, but I think your main issue is nitrogen toxicity. In soil grows, watering every day is not ideal, and feeding more than once a week is also not ideal. Either full strength every 10-14 days or half strength every 7 days. When watering, you should wet the entire pot throughly until you get run off, then do not water again until the top 3-4cm have dried out, be this one day or ten days. Keeping a plant constantly soggy with daily watering will cause issues and is not how cannabis likes to grow.
