First Grow - Yellow Leaves

Hey Everyone! Thanks a lot for you input. I have uploaded more photos of the yellow leaves in week 9 of my diary. Here are some more info as requested : @Roberts: Current pH - 6.41 (check photo in week 9 of the diary) Current TDS - 340 ppm (check photo in week 9 of the diary) I got those by taking some soil and pouring distilled water. After more or less 24h I have drained the water through a paper towel and took the measures. @Organoman: I am using 15l textile pot. I water every 3-4 days depending on how dry is the soil. Every time I water I use 2l of mineral water ( pH 5.80 and 13 TDS) mixed with the recommended amount of X-cel and PK 13-14. Should I water more often with less or ? @ChitownCannaChica I did got attacked by a grasshopper and got few leaves bit bitten but since then there where not bugs. I do have a mini microscope and I do check for any of them pests. I currently do not have any IPM. Any recommendation? Thanks again for everyone's help!

That doesn’t look like nutrient damage, but more like thrips. What’s your ipm?

As In not exact amounts. I have not used those nutrients is what I am saying

Here is what I would do. In flowering your plant wants potassium and phosphorus mainly. Nitrogen should wien off as flowering goes. TDS should be 1000 to 1400 range depending on plant size for a auto a few weeks from harvest. It is either nutrition burn or a potassium deficiency. It's really hard to tell. It's pretty early and I do not know exact amounts your feeding. I would check run off ph first though

Hey Roberts ! Thanks for the comment. So should I flush it? and for how long? Also I have been advice by a member to add CalMag? should I hold it for after the flush? (If I should do one)

Did had much space to add more details: ph of the soil is 6.3-6.7 Daytime humidity: 40 - 60% Night time humidity: 70 - 80% Daytime temp: 30C (34C max) Night time temp: 21C (18C min) She got attacked by a grasshopper yesterday.

Looks like your starting to get nutrition burn. In most cases half the bottle dose is too much. I would also check your run off ph. High dosing of nutrition can effect ph greatly if plant is not using it all in timely manner.
