Ok well I trimmed those that were burnt so if new ones continue to burn I still have the problem... My soils pH is 7.0! No matter what I do it stays that way even if I water with a lower pH such as 5.5. The burn came after the very first feed now they've lost there great smell
if u clipped the tips of all those leaves(if happends again wait untill u do the final trim before u jar it to remove them ) ....all those cuts are just that cuts into the vein system of the plant ....stress and open points for mold virus
add in 1 and half times the amount of b-52
the soil is hot ........that is no big thing
u have some rooting feed .......use that to increase the root mass lowing the hotness of the soil(basically give it the plant will partly redirect it to rooting lowing the what is going up to the plant) ....hormones trigger rooting response (Rapid start is the best one in 5 years of experiments )
a little nutr burn is a good thing .......alls it is it the plant is being offered to much food it is pigging out and damaging the cells some the higher amount of food (back it down (feed) .....flush the soil out....or build the root mass )
i grow auto plants i want to see burn ....it tells me i have tweaked the feed to the max the plant can handle i back it down 10 to 15% hold there and i know the buds are going to bend the branches from the weight
the fact your soil keeps going to 7.0ph is a very good thing it means the micros and fungi in the soil are happy and prefect ..........u can increase the chemical based feed to really weight build and use the organics for the taste profile
alls u did by running the water tho at that low of a PH is partly lock out the feed to the soil ......the micros had to balance it for it to in in the N
u did not decrease the hotness of the soil u just stressed the plant out some (keep a eye on nodes to much stress can hermi )
