1st Grow in 40 years

Josiah67 Steady p

Josiah67 All things appearing to be normal have been misting with rain

Josiah67 Have changed lighting from blue cfl 6400k to LED 100w G100 pro and increase PPFD from 300 to 350, topping out out 5 node

Josiah67 Watered with 0.5litres of rain water, have noticed that the stem and leaf stalk are red / purple, leaves are very vibrant

Josiah67 Leaves started to show signs of magnesium deficiency so treated with 8g/ltr of Epsom salts but after 4 days showed no sign of improvement. Watering has been only with rain water tested with ph 5.9. 02/11 watered with 2ml / ltr of Bio-Grow

Josiah67 Continued with Epsom salt and BioBizz WWO but unable to get any improvement so need to investigate other

Josiah67 Carried out flush with 2ltr water ph 6.9 , runoff after 10mins recorded at 6.2ph. Have done foliage spraying with the 30ml per Litre of water

Josiah67 1st week since swapping over to 12/12 light cycle, have started with cal mag as Epsom salts were not doing it. Also started with Terra Bloom which is something not available years ago and I think this was a bit of a shock to to plant as it has signs of nutrient overload on the lower leaves New growth is looking very good

Josiah67 Nutrient burn has become more prevalent so have undertaken another flush with rain water and will try again with just 0.5g/ml. The flowering is more evident and evenly spread across the plant. Will needs to see how humidity fluctuations along with daytime temperature effects the growth.

Josiah67 Buds are forming steadily, there hasn’t been much of a height growth since flowering started. Have removed a few of the lower fan leaves to allow a more consistent light canopy. Need to monitor humidity over the next couple of weeks, just a case of waiting for buds to fill out

Josiah67 Now in the waiting stage to see how the buds develop, have just been on a 1 ltr of rain water every 4 days with no added chemicals as I haven’t got a grip on the dosage that suits my growing medium. The buds aren’t going to be big but at least they’re forming

Josiah67 A issue this week has been a potassium deficiency that went from slight to severe in a week, as I am still flushing the soil I have used a 2g / litre potash foliage spray which is showing signs of addressing the K deficiency. Going to wait a few more days before giving another spray

Josiah67 I feel only one more week before harvest, they are going to be popcorn size buds but it has been a learning experience. Things that I will change for next grow, include LST, not leaving plant in veg state for so long, understanding of what these grow chemicals actually do, and even more research
