Yellow leave tips

[Ando87]

I am growing a plant that is 4 weeks in veg in soil in a 3 gallon pot under a 600w hps light and noticed that the tips of the leaves are turning yellow. I have flushed the plant for the last few days using only RO water as I thought it might be Nute burn but would like to get a second opinion as I am new to growing in case I am wrong. Would appreciate If some of the experts here could share some advice on how to address. Thanks

do you check your water ph when watering?
whats the temperature and humidity in grow tent?

 

[Ando87]

Temp in the tent is 26 degrees Celsius, ph 6.5 and humidity is 40%. I give it 3 litre every 3 days

I was thinking putting the 4 of them into flower next week but want try to remedy the yellow tips if possible before hand. I wonder is the water PH too high or if it is the nutrients? I have been using plagron terra grow, power roots and pure zym and the other 3 peyote critical seem to be okay just the super skunk is having the yellow tip. I am flushing her now and hoping for the best but any advice on how to remedy would be greatly appreciated.

The light had been off there for 5 hours also before I took the pictures

You said nute burn - what are you feeding? Also, you are in soil - which kind?

@Jeffislovinlife - Does PH at 6.5 in veg seems high? I use coco, not soil - but I have used soil in the past long ago and veg I was hitting 5.7 - 6 slightly acidic. Soil generally handles PH better no?

I'm thinking that is a good place to be at but I do use soil let's see if I can get you a better answer @Doug Dawson ca

This might help.

I use plagron light mix soil and use the grow box nutrients. 25ml of each of terra grow, 10 ml pure zym and 10ml power roots Per week, feed Around 2.7L 3 times per week per plant. I was thinking the tips of the leaves turning yellow may be Nute burn and started feeding that plant RO water without nutes for the last 4 days, but I think now it may have been heat stress so raised the light. I have a lot to learn!

 

[Jeffislovinlife]

Well sounds like you got a plan as always thank you for your time and the best of luck

Will see how she goes over the next few days, will probably add some more pictures to see what I can do to keep her on the straight and narrow

how are things looking now?? i have the same issue. was told it was possibly nut lockout.

Get a 10 or 20 gallon container. buy enough fox farm ocean forest to fill the container and transplant into it. that will solve your problem. don't give any extra nutrients unless you're absolutely certain you have to. otherwise only give water, don't bother pHing it.

6.5 in coco is to high
