started grow question 2y ago
Hello, I wanted to ask what kind of deficiency this could be, over-fertilization or if it's just due to the mediocre genetics? Thanks in advance!

Thats a sign of toxicity, your feeding is too rich, ussually comes with nitrogen excess, but here you are either in wrong NPK values or already in lockout. Rethink feeding ratios.

PH Fluctuation Early Signs?
I am worried that I either have early signs of PH fluctuations outside of 6.0-7.0 range or early signs of a calcium deficiency. As you can hopefully see in the picture the tips of the first set of true leave seem to have little spots of discolouration. Any help is appreciated😊

Can anyone identify what is happening with the lower shade leaves? A progressive, patchy paleness, from the spine of the leaf outwards and sides of leaves are cupping downwards. I gave cal/mag twice through the week along with bloom nutes. Is this a deficiency, small container..?

Spots on leafs, and lime green tops
I am beginning to see leaf damage again, so i would like to ask if you guys could point me in the direction of my problem. I suspect either light damage, or ph issues building up over time. It started before i gave the first flower nutes, tops seem deeper green since that though

The leaves on one plant started to turn a little pale, and with brown/purple spots. And on the other plant it starts to turn more yellow, probably Nitrogen deficiency for this one. What do you guys think ?

Too much light!
I downloaded a luxmeter app to have an idea of how many umol/s/m^2 my buds are getting and I discovered something unhappy... Some of them are getting between 2000 and 3600 umol/s/m^2. I'm getting my top buds light burnt but I cannot raise my lamp... Don't know what to do

Discolored, burnt and curled up tips on higher leaves
Several symptoms, always on tips of higher leaves : they are discolored/burnt or burnt/curled up. LED @40cm (deemed 70% of 300W) and I just gave them the 2nd flowering feeding, 4 days after first one (pots were very light). I was planing to start compost tea... What should I do ?

Day 40 from Seed Autoflower: Light Green Top Growth
Top of my 40 day old Blackberry Auto has gone light green. I am using 1000w of HID lighting and this is the tallest plant so I suspect light proximity, but I'd love second opinions.

Worth to continue the grow?
I've run into some problems and I think that this grow won't yield much. It's about week 7 and the damage is irreversible. Is it worth to continue the grow or just start from the scratch? Don't want to waste electricity for few grams of weed. Check my diary for more info. Thanks
