Hi all my second grow is well under way and my leaves have just started to show these markings, have been following the biobiz schedule for feeding at 50% strength, these were planted 9th dec and are well into flower. Had no issue until the last two days and haven’t done anything different.
two plants growing one is gorilla glue and the other is pineapple express
soil grow using bat mix
PH is 5.6 generally
ph is too low mate, you need to be around 6.5 in bat mix. probably lock out because of it. give them just a plain water feed at 6.5, and the watering after add some feed, and also ph that to 6.5
This should stop the issue

Thanks Macky, I really seem to find it difficult to get the Ph correct, I’m always up/down and never get it where I want it.

Dilute the PH up/down with water before adding, easier to get it exact 😉
My water usually runs around A PH of 8, I generally mix several gallons for my auto watering system. Normally I start with 10 drops and see how much change this creates in the PH of my Water, Lets say this changed my PH by .2 and I need to go another 1.2 PH down requiring 60 drops Ill put in Half and recheck then add half of what I expect to get me to the final PH and recheck PH, Doing it this way has helped me in getting my PH were I need it to be.
Sativa to change the things I can, Indica to accept the things I can’t.
using neat ph down, it will only take like 1 drop to change 1 litre from 6.0 to 4.0 lol its very strong
In my 15l bucket, id use 3 drops to bring my water from 6.4, down to 5.8, and sometimes that can hit 5.7 lol
Like ZN said mate, Dilute some, get 990 ml of water, and add 10ml of ph down to make a litre. This will make it so much easier to find the right bance

yer think mine is vitalink, im not sure. Too powerful mate, but you get used to it. Need a pipette to use it properly. Otherwise, dilute it... or use lemon juice 😉

definatly would work good in an automated dripper system tho. us clumsy humans tho.... lol
GH is all Ive tried other than natural stuff. I also use a pipette and slowly get it where I need it to be, after hearing this I can understand where people have issues over shooting their mark.
