Has to be quite alkaline to inhibit nitrogen uptake as i understand it whilst phosphorous uptake is quickly inhibited by even slight acidity. I think in my case the goal is to prevent phosphorous deficiency and especially now 4 weeks into bloom. https://www.growweedeasy.com/ph It's kind of...

I think i got too trigger happy and careless. Ash is what i had at hand and there are no means of getting anything else for 5 days. I figured that the soil was kind of low to begin with @5.9, googled that rain water is 5-5.5, so i figured the soil must be getting well acidified by now...

As i understand it, wood ash is ph up. I top dressed some and added ash to the water in order to increase it's ph as well.

I was considering using wood ash

I've smoked the different dmts, idk the correct terminology but there is one type that is relatively mild and another that i can only compare to hitting 40x salvia divinorium through a bong. The mild version was really cool in terms of visuals and pleasant. The strong version was extremely...

Hi take a look pls Plants are 41 days since sprouting out of soil and 27 days since flipped 12/12. They are in a premade synthetically prefertilized soil with compost, sand & perlite mix. It's starting ph is 5.9 Pots are 0.8gallon I give rainwater only. Did once foliar sprayed groundwater...

Day 40 The leaves were definitely nute burnt. Can't easily lower the lights due to temps getting high so i will have to take that L or keep trying to control temps. Pistils seem to regrow. Will probably flush the soil in a week or two.

Something is definitely wrong and it's starting to show. First the pistils and now the leaftips are yellowing. I will examine the lower growth tomorrow and move the light back if the lower leaves are also with yellow tips. Actually i will probably move them back down either way. 4-5 weeks left...

I didn't take note of this. Thanks for you analysis. I also noticed scortched tips on leaves and am confident now.

This week i've had some problems with damaged pistils as i made some mistakes when foliar feeding. 11 days since started making pistils I don't think i did any irreparable damage with the spray but it scortched them pretty bad as i also had 10/2/4 npk mixed in there at 1:7 rate. This is the...

The plants are 2 weeks since buds started developing. Medium is synthetically prefertilized soil, compost, sand & perlite. Lights are a panel of 9 led bulbs with 1 watt samsung diodes, diffusers off. Total of148watt and 12.5k lumens over 1.3 sqft. When i was growing the seedlings i kept them...

I think the only thing one can try is some antifungal application allover incl underside of leaf. Maybe diluted garlic/onion juice? Basically foliar feed antifungal and cut or scrape of what is affected. I think that's what i would do and research fungicide options

How did this work out?

I am not sure what is mixing soil but whatever you had to begin with worked so far. Maybe just put them in a small container with drainage holes 250ml or so and see if it recovers. When transplanting just don't rush it and be very gentle. Also when you made that cut, i think it's better to...

Just saw ur room size is 2.42188 sq/ft Your light is fine for now but you shpuld at least double it if you have a canopy covering the entirety of those 2.42188 sq/ft. Your light is ok for 1. Also get some air circulation in that box

Let it dry until you can stick a finger some 2cm in and it feels dry. It is better to give them just a little bit of water directly where the roots are and wait until it gets dry or that the plant shows that it's thirsty (leaves will start hanging down). They don't need much light at this...

Well it looks like mold and when watering you have to think about the size of the root and how there is no point in watering the whole pot of soil because that water is just going to sit there, not being used by the plant, evaporating very slowly and low temperature doesn't help that.

I don't know. It looks like mold to me and i think cutting off the affected parts is what i would do if i didn't get any better advice. I would do it before it spread to the trueleafs.. Is your growroom very humid? You have to be careful not to overwater at this stage and if you have these...

Sun at noon is about 110k lumens per sq meter. If you have 12k lumens covering a m2 then you need a lot more but if the space is say 1/10 of a m2 then you have enough. The color of light matters but you can grow and flower a plant with either color, it won't be optimal of course but your plant...

I looked at a bunch of resources and i think these plants should be getting ready for death around mid april.
