Something ate a hole in a leaf last night. It not a complete hole through just the chrolophyll was scraped off, leaving a yellow bite mark (picture in diary). I removed a caterpillar looking thing from my tent this morning, no idea how it got there. Could that have been it?

Nute Burn Plan. Lower light to 24 inches and turn on bloom switch. Flush soil with 8 litres of water (PH 6.5) per pot. Questions: will increasing the intensity of light increase plants ability to absorb nutrients, or simply stress them more? Is 8L water/ 10L pot enough to flush?

The leaves are wierd shaped, but growing fast Hi everyone! Please tell me, is it a consequence of leaf scorch with light, or incorrect watering, or I was very in vain in the beginning added root booster? The big question is, is it worth waiting for a potential recovery?There's nothing like it at google

Browning/Yellowing tips Both of my GSC's are suffering from browning/yellowing tips? will they recover? is this because of heat stress, nitrogen deficiency or over-watering? or something else? The second plant seems to have the most browning/yellowing fan leaf tips and first plant had little to none.

yellow spots on upper leaves, towards the end of flowering, I grow in a Coco ,flowering 8/10 This is my second attempt at cocus I work with Plagron nutrient solutions(Coco Nutrient) I follow the table, there were no problems on my first try.. should i stop nutrients? I always mix the water in a bucket, so I can't spoil it either, because most of the plants are healthy, ph 5.5 is always between 5-7!
