Is this a problem

My plants are midway though wk4.

Autoflower Northern lights cream.

Growing in biobizz light mix.

Ive got some bleaching of the tips. Not sure if its light stress or over feeding. Also 1 of the plants preys to the gods while the other 2 dont perk up so much.

Just staring to flower.

Feeding 0.25ml grow, 0.75ml fishmix, 0.50ml bloom, 0.50ml top max, 0.75ml Calmag. Per ltr.

Ive not ph'ed the water or feed uptill now. Not sure if I need too.

Just ph'ed feed/water and its 6.9

My thoughts are: light was too low causing light stress, and ph being high making the plants not happy.

The more I read on subject the more I seem to just go round in circles.

If you’re bottle feeding and not using a living soil you need to ph your water.Water ph is just as important as feeding your plants, If your ph is off your plants will not uptake nutrients. I’ve found this to be the most common issue people come across. Go to the hydro store and buy a ph pen, calibration fluid, some ph up and ph down. You’re aiming for a ph of 6.5 for maximum nutrients absorption.(Hydroponics calls for a lower ph, around 5.5 is ideal)

Ok, I have all the ph'ing kit just not used it as most people told me not to ph when growing in soil. I Guess light mix is different then.

I've just mixed up a new batch of feed with a PH of 6.35, i'm guessing that should help correct the ph of the soil. Then next mix 6.5. ?

Every batch has to be around 6.2-6.8 so ideally you’ll want it at 6.5. Is your tap water +nutrient solution high or low ph without correction?

It’s not important to ph your soil if you use organic amendments like bonemeal, bat guano, insect frass, shrimp meal, kelp meal, basalt rock dust, earth worm castings, feather meal, oyster shells etc... bottled nutrients usually destroy the microbiology in your soil that would naturally regulate your ph.

My water is 7.2 then when i add all my feeds its 6.9.

TBh im losing the fucking plot right now. i moved from hps high heat high RH, did 3 runs of autos with none of the problems im having now.

I went this route because people at uk420 told me too.

but since then ive had nothing but problem 20 failed seeds then when they do germinate they have multiple problems

There must be a simple way of growing some standard weed, im not after high grade just somthing that helsp you relax and sleep....

all these fucking chemicals, ph soils lights .... etc there has to be a simpler way

To be completely honest im 3 seconds away from soaking my my house in petrol and burning the lot with my self in it.

before this fucking covid shit i had a steady supply of buds for over 15 years, now i cant get shit, lost £300 on the dark web trying to get a delivery...

Im honestly so close to calling it a fucking day.
