Help....leaves slight yellowing with small brown spots along the veins

**stealthbonger** · 30-08-20, 05:19 AM

I'm trial and error with this, so far I've flushed the soil... I'm thinking to add some Epsom salt and calcium to a lighter feed when the soils dried out a bit.
What would be the best way of providing manganese to the soil?

Must say I'm a bit lost with this, I've flushed the soil with 6.0 pH'd water, just waiting for the soil to dry then ill start feeding again... Any suggestions really appreciated.

Hello, ive been struggling a bit to work this issue out, the issue spread to all leaves on both the NL! However the buds matured and ive now chopped both the NL.
I flushed the NL and then slowly introduced nutes again, i think the problem impacted on the yield in the final week or two, but overall im fairly pleased with my first grow.... i think i need to pay alot more attention when the flowering starts as up to that point everything was sailing along.

The single gorilla glue auto ive been growing has also developed the same symptoms although not a bad... the things ive tried with this lady so far was very carefully using a copper solution on the leaves, flusghing with 6.0ph water and then reintroducing nutes and water at 6.3ph and adding a tea spoon of crushed egg shell solution to the feed and also raising the light to 21" from the canopy... now the issue seem to be halted apart from a bit of yellowing to the lower leaves due to the flush.
The buds are maturing now and looks about a week or two from harvest so im just going to let it run and do a 7 day flush after the next feed.

Is it possible that the 24/0 light schedule and maybe the light being a little to close maybe responsible for the issues ive had?
The tips of many of the leaves on the GG have curled upwards as ive progressed through flowering and the brown spots could be burns from light intensity?.

Or is it a lack of attention to the early flowering stage and nute issues thats the problem?

Ive read about issues with the biobizz nutes.... but like i say everything was good until flowering...

Best bet, next grow get a diary from start to finish, unsure if you did on this grow, but problems are easier to trace, gives ppl more info. Stick some pics up if you've still got a plant on the go with this problem.

I had an issue where I overfed calcium which looked the same as when I had an issue with lockout due to the waterings having to high pH level.

Sorry for jumping in but 1.5 litres each time you water for 11 tubs, is this still the case?

Its was for a while as i seemed to get quite a bit of run off even at 1.5L, i upped to 2.5L when the pots began to dry quicker during flowering.
In the last week or 2 before cropping the NL the plants didnt really drink very much which again had me a bit baffled..

Mine are about ready to chop and taking water/feed alot slower but no issues. Didnt notice the water given, I reckon I give 4 ltr in a 15 ltr pot and get a drizzle, thats for what I'm growing now

I use the same soil and have for years now, just my observations on growing autos in soil is that as you get closer to harvest fans leaves start turning to shite whatever I do ( just a toss grower greengrass) but as long the buds are pukka and look imaculate I've stopped chasing my arse worrying about deficiencies on fan leaves mukka
I mean there is perfection in growing in dirt I've seen it here
I don't offer up any diaries so take what I say with a borrow of salt but get to harvest, fill you jars then smile ?
