As title says

Seems to hit the most affected leaves with LSF



Just read OT1 recomends 1 to 1.5ml per litre of catalyst

Question

What is the least amount of Catalyst i can use in my essence brew? ( per litre )

many thanks

hb

0.5 ml per litre would be fine.

This run im using 6 litre pots

Previously 4 litre

Could it be additives in compost?

bat poo - rock dust - calcified seaweed ?

Many thanks OT1

on 1ml grow and 3ml bloom

Just looking at the under side of removed leaves

looking up to kitchen light from underneath

not much LSF - dark patches - less than i thought

hb

I think i see patern

the leaves affected by LSF and nute burn

Seem to have the longest stems - longest leaves

If that makes sense

The pics are like postage stamps on my screen [1920 x 1200] so its a bit hard to see, but from what I can see:- No nutrient problem, you do have leaf fungal infection damaging veins causing necrotic patches of leaves. I can't see leaf spot as such, but it may be there as well. The thing to do is cut back infected leaf to clean tissue, then spraying with essence immediately after.

This keeps as much sun leaf as possible, these are what produce the energy that makes the buds.

A pic of where to cut back:- Click to view attachment Where leaves are badly infected remove entirely.

This may need doing several times, ie cut back and spray, you need to keep on top of it to stop spores being released in the grow room.

To reduce infection levels it is very important to keep removing any infected tissue from the grow room while retaining as much good tissue as you can to photosynthesize.

as ot said .I had same probs at a similar time on 1 pheno of killer but worse .I cut leaves back and sprayed every 5 days till 2 weeks before chop and they made it through fine,just have to keep on top of it!ive cut back on the catayst as its powerful stuff as is the bio-silicon that ive been using,managed to burn my mums quite badly through experimenting

Many thanks OT1

Yes there is some rust spots and black spots

A lesson for everyone!
