After switching the light schedule, our supposed "autoflowers" have finaly started to show signs of actually flowering. Week 9, what a trip.
This grow is full of surprises and new lessons for me: the potting mix i have used for this grow is apparently purely peat (black and white peat moss) with perlite mixed in. After digging into some more information about all kinds of soils i found out that i was apparently growing "hydroponically" because this is apparently a soilless mix. The world is full of surprises ๐
This does explain a lot of the stuff that i've been trying to deal with in the last few weeks: first and foremost my plants were looking like they were developing a range of different nutrient deficiencies. I still find it hard to tell which ones, but symptoms ranged from decoloration and deformation of the lower leafs up to small burnt tips on the developing flowers, new growth being brittle and signs that looked like underwatering. I'm convinced that this has a lot to do with the fact tht this is a soilless medium with 0 pre-supplied nutrients (the light mix does supply nutrients for a week or two, but no more). I've been going really slow on the feeding because in previous runs i tended to overfeed and had issues with that, so therefore only used about a quarter to half of the recommended dosages.
So, at this point i've completely switched up my feeding: i bought 2 new bottles of hydroponic fertilizers (GHE Bloom and GHE Micro) and i'm using those in addition to a little bit of plagron terra grow - to make sure the plant also gets its fair share of nitrogen. After 3 days of watering with this stuff (both at 2ml/L) the plants are almost literally screaming "THANK YOU!" and seem to be really benefitting from this new insight and change of strategies.
some of the bottom leaves (all 3 plants affected) are slightly curling up towards the end. she looks pretty healthy to me, so i'm wondering if anyone here recognises this and knows what might cause such symptoms?
@levensfiets hi there my friend I'm thinking that this is a classic case of overwatering you need to allow the medium your growing in time to dry a little between
waterings this is to let your roots breathe .
(for more background, see Week 9 in diary)
Am i correct for assuming that when growing in peat moss (supplemented with perlite) i would need a hydroponic fertilizer because this is a soilless medium? thanks ! :)
Look into Coco nutes! I used ProMix during my first grow and I had to get the PH Perfect line from Advanced Nutrients ๐
Had to keep up with plenty of feedings once I dialed in the right levels. I backed off to a 70/30 Soil to ProMix combo for my second grow so I didn't have to keep up with as many feedings.
Best of luck! ๐
Trichomes on #2 are underdeveloped. Do you guys reckon it would help buying a UVB lamp (10 rating) 26 watt and adding those to both growrooms to compensate for the LED's lack of UV lighting? Maybe some Molasses in the feeding (never used it before) ?
@levensfiets I'm not too savvy on the uv lights but I can definately reccomend the use of mollasses in your feeds as it does wonders for the soil microbes
Remember happy soil= happy roots then that = happy Fruits I use a tablespoon per 10L watering can otherwise you could go with just a couple of teaspoons to start with
Good luck for your culture my friend ๐ i replied to your grow question if the answer suits you you can validate it ๐ if you need advice do not hesitate
May the strength be with you ๐ช
Congrats ! Im just getting into growing i was wondering how the LUMERI PNLVB1200 LED light performs. I was interested in buying it as my first lamp. Do you reccomend it ? .. I cant find anything regarding that lamp. Thanks in advance.
@elusion84, i think i like it, although i have nothing to compare it with yet. also a big downside to this light is that there are no available specs in terms of ppfd and things like that ('ve been in touch with the reseller and they are unable to give me any info)
however; if i'd have to buy a new one in the same pricerange based on my current knowledge i'd buy and optic 1XL or an optic2 i guess.
